------------------------------------------------------------------------------
Name
 
  cmake - Cross-Platform Makefile Generator.
 
------------------------------------------------------------------------------
Usage
 
  cmake [options] <path-to-source>
  cmake [options] <path-to-existing-build>
 
------------------------------------------------------------------------------
Description
 
The "cmake" executable is the CMake command-line interface.  It may be used
to configure projects in scripts.  Project configuration settings may be
specified on the command line with the -D option.  The -i option will cause
cmake to interactively prompt for such settings.
 
CMake is a cross-platform build system generator.  Projects specify their
build process with platform-independent CMake listfiles included in each
directory of a source tree with the name CMakeLists.txt.  Users build a
project by using CMake to generate a build system for a native tool on their
platform.
 
------------------------------------------------------------------------------
Options
 
  -C <initial-cache>
      Pre-load a script to populate the cache.
 
      When cmake is first run in an empty build tree, it creates a
      CMakeCache.txt file and populates it with customizable settings for
      the project.  This option may be used to specify a file from which to
      load cache entries before the first pass through the project's cmake
      listfiles.  The loaded entries take priority over the project's
      default values.  The given file should be a CMake script containing
      SET commands that use the CACHE option, not a cache-format file.
 
  -D <var>:<type>=<value>
      Create a cmake cache entry.
 
      When cmake is first run in an empty build tree, it creates a
      CMakeCache.txt file and populates it with customizable settings for
      the project.  This option may be used to specify a setting that takes
      priority over the project's default value.  The option may be repeated
      for as many cache entries as desired.
 
  -U <globbing_expr>
      Remove matching entries from CMake cache.
 
      This option may be used to remove one or more variables from the
      CMakeCache.txt file, globbing expressions using * and ? are supported.
      The option may be repeated for as many cache entries as desired.
 
      Use with care, you can make your CMakeCache.txt non-working.
 
  -G <generator-name>
      Specify a makefile generator.
 
      CMake may support multiple native build systems on certain platforms.
      A makefile generator is responsible for generating a particular build
      system.  Possible generator names are specified in the Generators
      section.
 
  -Wno-dev
      Suppress developer warnings.
 
      Suppress warnings that are meant for the author of the CMakeLists.txt
      files.
 
  -Wdev
      Enable developer warnings.
 
      Enable warnings that are meant for the author of the CMakeLists.txt
      files.
 
  -E
      CMake command mode.
 
      For true platform independence, CMake provides a list of commands that
      can be used on all systems.  Run with -E help for the usage
      information.  Commands availble are: chdir, copy, copy_if_different
      copy_directory, compare_files, echo, echo_append, environment,
      make_directory, md5sum, remove_directory, remove, tar, time, touch,
      touch_nocreate, write_regv, delete_regv, comspec, create_symlink.
 
  -i
      Run in wizard mode.
 
      Wizard mode runs cmake interactively without a GUI.  The user is
      prompted to answer questions about the project configuration.  The
      answers are used to set cmake cache values.
 
  -L[A][H]
      List non-advanced cached variables.
 
      List cache variables will run CMake and list all the variables from
      the CMake cache that are not marked as INTERNAL or ADVANCED.  This
      will effectively display current CMake settings, which can be then
      changed with -D option.  Changing some of the variable may result in
      more variables being created.  If A is specified, then it will display
      also advanced variables.  If H is specified, it will also display help
      for each variable.
 
  -N
      View mode only.
 
      Only load the cache.  Do not actually run configure and generate
      steps.
 
  -P <file>
      Process script mode.
 
      Process the given cmake file as a script written in the CMake
      language.  No configure or generate step is performed and the cache is
      not modified.  If variables are defined using -D, this must be done
      before the -P argument.
 
  --graphviz=[file]
      Generate graphviz of dependencies.
 
      Generate a graphviz input file that will contain all the library and
      executable dependencies in the project.
 
  --system-information [file]
      Dump information about this system.
 
      Dump a wide range of information about the current system.  If run
      from the top of a binary tree for a CMake project it will dump
      additional information such as the cache, log files etc.
 
  --debug-trycompile
      Do not delete the try compile directories..
 
      Do not delete the files and directories created for try_compile calls.
      This is useful in debugging failed try_compiles.  It may however
      change the results of the try-compiles as old junk from a previous
      try-compile may cause a different test to either pass or fail
      incorrectly.  This option is best used for one try-compile at a time,
      and only when debugging.
 
  --debug-output
      Put cmake in a debug mode.
 
      Print extra stuff during the cmake run like stack traces with
      message(send_error ) calls.

      Put cmake in trace mode.
 
      Print a trace of all calls made and from where with message(send_error
      ) calls.

------------------------------------------------------------------------------
Generators
 
The following generators are available on this platform:
 
  Unix Makefiles
      Generates standard UNIX makefiles.
 
      A hierarchy of UNIX makefiles is generated into the build tree.  Any
      standard UNIX-style make program can build the project through the
      default make target.  A "make install" target is also provided.
 
  CodeBlocks - Unix Makefiles
      Generates CodeBlocks project files.
 
      Project files for CodeBlocks will be created in the top directory and
      in every subdirectory which features a CMakeLists.txt file containing
      a PROJECT() call.  Additionally a hierarchy of makefiles is generated
      into the build tree.  The appropriate make program can build the
      project through the default make target.  A "make install" target is
      also provided.
 
  Eclipse CDT4 - Unix Makefiles
      Generates Eclipse CDT 4.0 project files.
 
      Project files for Eclipse will be created in the top directory and
      will have a linked resource to every subdirectory which features a
      CMakeLists.txt file containing a PROJECT() call.Additionally a
      hierarchy of makefiles is generated into the build tree.  The
      appropriate make program can build the project through the default
      make target.  A "make install" target is also provided.
 
  KDevelop3
      Generates KDevelop 3 project files.
 
      Project files for KDevelop 3 will be created in the top directory and
      in every subdirectory which features a CMakeLists.txt file containing
      a PROJECT() call.  If you change the settings using KDevelop cmake
      will try its best to keep your changes when regenerating the project
      files.  Additionally a hierarchy of UNIX makefiles is generated into
      the build tree.  Any standard UNIX-style make program can build the
      project through the default make target.  A "make install" target is
      also provided.
 
  KDevelop3 - Unix Makefiles
      Generates KDevelop 3 project files.
 
      Project files for KDevelop 3 will be created in the top directory and
      in every subdirectory which features a CMakeLists.txt file containing
      a PROJECT() call.  If you change the settings using KDevelop cmake
      will try its best to keep your changes when regenerating the project
      files.  Additionally a hierarchy of UNIX makefiles is generated into
      the build tree.  Any standard UNIX-style make program can build the
      project through the default make target.  A "make install" target is
      also provided.
 
------------------------------------------------------------------------------
Commands
 
  add_custom_command
      Add a custom build rule to the generated build system.
 
      There are two main signatures for add_custom_command The first
      signature is for adding a custom command to produce an output.
 
        add_custom_command(OUTPUT output1 [output2 ...]
                            COMMAND command1 [ARGS] [args1...]
                            [COMMAND command2 [ARGS] [args2...] ...]
                            [MAIN_DEPENDENCY depend]
                            [DEPENDS [depends...]]
                            [IMPLICIT_DEPENDS <lang1> depend1 ...]
                            [WORKING_DIRECTORY dir]
                            [COMMENT comment] [VERBATIM] [APPEND])
 
      This defines a new command that can be executed during the build
      process.  The outputs named should be listed as source files in the
      target for which they are to be generated.  If an output name is a
      relative path it will be interpreted relative to the build tree
      directory corresponding to the current source directory.  Note that
      MAIN_DEPENDENCY is completely optional and is used as a suggestion to
      visual studio about where to hang the custom command.  In makefile
      terms this creates a new target in the following form:
 
        OUTPUT: MAIN_DEPENDENCY DEPENDS
                COMMAND
 
      If more than one command is specified they will be executed in order.
      The optional ARGS argument is for backward compatibility and will be
      ignored.
 
      The second signature adds a custom command to a target such as a
      library or executable.  This is useful for performing an operation
      before or after building the target.  The command becomes part of the
      target and will only execute when the target itself is built.  If the
      target is already built, the command will not execute.
 
        add_custom_command(TARGET target
                            PRE_BUILD | PRE_LINK | POST_BUILD
                            COMMAND command1 [ARGS] [args1...]
                            [COMMAND command2 [ARGS] [args2...] ...]
                            [WORKING_DIRECTORY dir]
                            [COMMENT comment] [VERBATIM])
 
      This defines a new command that will be associated with building the
      specified target.  When the command will happen is determined by which
      of the following is specified:
 
        PRE_BUILD - run before all other dependencies
        PRE_LINK - run after other dependencies
        POST_BUILD - run after the target has been built
 
      Note that the PRE_BUILD option is only supported on Visual Studio 7 or
      later.  For all other generators PRE_BUILD will be treated as
      PRE_LINK.
 
      If WORKING_DIRECTORY is specified the command will be executed in the
      directory given.  If COMMENT is set, the value will be displayed as a
      message before the commands are executed at build time.  If APPEND is
      specified the COMMAND and DEPENDS option values are appended to the
      custom command for the first output specified.  There must have
      already been a previous call to this command with the same output.
      The COMMENT, WORKING_DIRECTORY, and MAIN_DEPENDENCY options are
      currently ignored when APPEND is given, but may be used in the future.
 
      If VERBATIM is given then all the arguments to the commands will be
      passed exactly as specified no matter the build tool used.  Note that
      one level of escapes is still used by the CMake language processor
      before ADD_CUSTOM_TARGET even sees the arguments.  Use of VERBATIM is
      recommended as it enables correct behavior.  When VERBATIM is not
      given the behavior is platform specific.  In the future VERBATIM may
      be enabled by default.  The only reason it is an option is to preserve
      compatibility with older CMake code.
 
      If the output of the custom command is not actually created as a file
      on disk it should be marked as SYMBOLIC with
      SET_SOURCE_FILES_PROPERTIES.
 
      The IMPLICIT_DEPENDS option requests scanning of implicit dependencies
      of an input file.  The language given specifies the programming
      language whose corresponding dependency scanner should be used.
      Currently only C and CXX language scanners are supported.
      Dependencies discovered from the scanning are added to those of the
      custom command at build time.  Note that the IMPLICIT_DEPENDS option
      is currently supported only for Makefile generators and will be
      ignored by other generators.
 
      If COMMAND specifies an executable target (created by ADD_EXECUTABLE)
      it will automatically be replaced by the location of the executable
      created at build time.  Additionally a target-level dependency will be
      added so that the executable target will be built before any target
      using this custom command.  However this does NOT add a file-level
      dependency that would cause the custom command to re-run whenever the
      executable is recompiled.
 
      If DEPENDS specifies any target (created by an ADD_* command) a
      target-level dependency is created to make sure the target is built
      before any target using this custom command.  Additionally, if the
      target is an executable or library a file-level dependency is created
      to cause the custom command to re-run whenever the target is
      recompiled.
 
 
  add_custom_target
      Add a target with no output so it will always be built.
 
        add_custom_target(Name [ALL] [command1 [args1...]]
                          [COMMAND command2 [args2...] ...]
                          [DEPENDS depend depend depend ... ]
                          [WORKING_DIRECTORY dir]
                          [COMMENT comment] [VERBATIM]
                          [SOURCES src1 [src2...]])
 
      Adds a target with the given name that executes the given commands.
      The target has no output file and is ALWAYS CONSIDERED OUT OF DATE
      even if the commands try to create a file with the name of the target.
      Use ADD_CUSTOM_COMMAND to generate a file with dependencies.  By
      default nothing depends on the custom target.  Use ADD_DEPENDENCIES to
      add dependencies to or from other targets.  If the ALL option is
      specified it indicates that this target should be added to the default
      build target so that it will be run every time (the command cannot be
      called ALL).  The command and arguments are optional and if not
      specified an empty target will be created.  If WORKING_DIRECTORY is
      set, then the command will be run in that directory.  If COMMENT is
      set, the value will be displayed as a message before the commands are
      executed at build time.  Dependencies listed with the DEPENDS argument
      may reference files and outputs of custom commands created with
      ADD_CUSTOM_COMMAND.
 
      If VERBATIM is given then all the arguments to the commands will be
      passed exactly as specified no matter the build tool used.  Note that
      one level of escapes is still used by the CMake language processor
      before add_custom_target even sees the arguments.  Use of VERBATIM is
      recommended as it enables correct behavior.  When VERBATIM is not
      given the behavior is platform specific.  In the future VERBATIM may
      be enabled by default.  The only reason it is an option is to preserve
      compatibility with older CMake code.
 
      The SOURCES option specifies additional source files to be included in
      the custom target.  Specified source files will be added to IDE
      project files for convenience in editing even if they have not build
      rules.
 
  add_definitions
      Adds -D define flags to the compilation of source files.
 
        add_definitions(-DFOO -DBAR ...)
 
      Adds flags to the compiler command line for sources in the current
      directory and below.  This command can be used to add any flags, but
      it was originally intended to add preprocessor definitions.  Flags
      beginning in -D or /D that look like preprocessor definitions are
      automatically added to the COMPILE_DEFINITIONS property for the
      current directory.  Definitions with non-trival values may be left in
      the set of flags instead of being converted for reasons of backwards
      compatibility.  See documentation of the directory, target, and source
      file COMPILE_DEFINITIONS properties for details on adding preprocessor
      definitions to specific scopes and configurations.
 
  add_dependencies
      Add a dependency between top-level targets.
 
        add_dependencies(target-name depend-target1
                          depend-target2 ...)
 
      Make a top-level target depend on other top-level targets.  A
      top-level target is one created by ADD_EXECUTABLE, ADD_LIBRARY, or
      ADD_CUSTOM_TARGET.  Adding dependencies with this command can be used
      to make sure one target is built before another target.  See the
      DEPENDS option of ADD_CUSTOM_TARGET and ADD_CUSTOM_COMMAND for adding
      file-level dependencies in custom rules.  See the OBJECT_DEPENDS
      option in SET_SOURCE_FILES_PROPERTIES to add file-level dependencies
      to object files.
 
  add_executable
      Add an executable to the project using the specified source files.
 
        add_executable(<name> [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL]
                        source1 source2 ... sourceN)
 
      Adds an executable target called <name> to be built from the source
      files listed in the command invocation.  The <name> corresponds to the
      logical target name and must be globally unique within a project.  The
      actual file name of the executable built is constructed based on
      conventions of the native platform (such as <name>.exe or just
      <name>).
 
      By default the executable file will be created in the build tree
      directory corresponding to the source tree directory in which the
      command was invoked.  See documentation of the
      RUNTIME_OUTPUT_DIRECTORY target property to change this location.  See
      documentation of the OUTPUT_NAME target property to change the <name>
      part of the final file name.
 
      If WIN32 is given the property WIN32_EXECUTABLE will be set on the
      target created.  See documentation of that target property for
      details.
 
      If MACOSX_BUNDLE is given the corresponding property will be set on
      the created target.  See documentation of the MACOSX_BUNDLE target
      property for details.
 
      If EXCLUDE_FROM_ALL is given the corresponding property will be set on
      the created target.  See documentation of the EXCLUDE_FROM_ALL target
      property for details.
 
      The add_executable command can also create IMPORTED executable targets
      using this signature:
 
        add_executable(<name> IMPORTED)
 
      An IMPORTED executable target references an executable file located
      outside the project.  No rules are generated to build it.  The target
      name has scope in the directory in which it is created and below.  It
      may be referenced like any target built within the project.  IMPORTED
      executables are useful for convenient reference from commands like
      add_custom_command.  Details about the imported executable are
      specified by setting properties whose names begin in "IMPORTED_".  The
      most important such property is IMPORTED_LOCATION (and its
      per-configuration version IMPORTED_LOCATION_<CONFIG>) which specifies
      the location of the main executable file on disk.  See documentation
      of the IMPORTED_* properties for more information.
 
  add_library
      Add a library to the project using the specified source files.
 
        add_library(<name> [STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL]
                    source1 source2 ... sourceN)
 
      Adds a library target called <name> to be built from the source files
      listed in the command invocation.  The <name> corresponds to the
      logical target name and must be globally unique within a project.  The
      actual file name of the library built is constructed based on
      conventions of the native platform (such as lib<name>.a or
      <name>.lib).
 
      STATIC, SHARED, or MODULE may be given to specify the type of library
      to be created.  STATIC libraries are archives of object files for use
      when linking other targets.  SHARED libraries are linked dynamically
      and loaded at runtime.  MODULE libraries are plugins that are not
      linked into other targets but may be loaded dynamically at runtime
      using dlopen-like functionality.  If no type is given explicitly the
      type is STATIC or SHARED based on whether the current value of the
      variable BUILD_SHARED_LIBS is true.
 
      By default the library file will be created in the build tree
      directory corresponding to the source tree directory in which the
      command was invoked.  See documentation of the
      ARCHIVE_OUTPUT_DIRECTORY, LIBRARY_OUTPUT_DIRECTORY, and
      RUNTIME_OUTPUT_DIRECTORY target properties to change this location.
      See documentation of the OUTPUT_NAME target property to change the
      <name> part of the final file name.
 
      If EXCLUDE_FROM_ALL is given the corresponding property will be set on
      the created target.  See documentation of the EXCLUDE_FROM_ALL target
      property for details.
 
      The add_library command can also create IMPORTED library targets using
      this signature:
 
        add_library(<name> <SHARED|STATIC|MODULE|UNKNOWN> IMPORTED)
 
      An IMPORTED library target references a library file located outside
      the project.  No rules are generated to build it.  The target name has
      scope in the directory in which it is created and below.  It may be
      referenced like any target built within the project.  IMPORTED
      libraries are useful for convenient reference from commands like
      target_link_libraries.  Details about the imported library are
      specified by setting properties whose names begin in "IMPORTED_".  The
      most important such property is IMPORTED_LOCATION (and its
      per-configuration version IMPORTED_LOCATION_<CONFIG>) which specifies
      the location of the main library file on disk.  See documentation of
      the IMPORTED_* properties for more information.
 
  add_subdirectory
      Add a subdirectory to the build.
 
        add_subdirectory(source_dir [binary_dir]
                          [EXCLUDE_FROM_ALL])
 
      Add a subdirectory to the build.  The source_dir specifies the
      directory in which the source CmakeLists.txt and code files are
      located.  If it is a relative path it will be evaluated with respect
      to the current directory (the typical usage), but it may also be an
      absolute path.  The binary_dir specifies the directory in which to
      place the output files.  If it is a relative path it will be evaluated
      with respect to the current output directory, but it may also be an
      absolute path.  If binary_dir is not specified, the value of
      source_dir, before expanding any relative path, will be used (the
      typical usage).  The CMakeLists.txt file in the specified source
      directory will be processed immediately by CMake before processing in
      the current input file continues beyond this command.
 
      If the EXCLUDE_FROM_ALL argument is provided then targets in the
      subdirectory will not be included in the ALL target of the parent
      directory by default, and will be excluded from IDE project files.
      Users must explicitly build targets in the subdirectory.  This is
      meant for use when the subdirectory contains a separate part of the
      project that is useful but not necessary, such as a set of examples.
      Typically the subdirectory should contain its own project() command
      invocation so that a full build system will be generated in the
      subdirectory (such as a VS IDE solution file).  Note that inter-target
      dependencies supercede this exclusion.  If a target built by the
      parent project depends on a target in the subdirectory, the dependee
      target will be included in the parent project build system to satisfy
      the dependency.
 
  add_test
      Add a test to the project with the specified arguments.
 
        add_test(testname Exename arg1 arg2 ...)
 
      If the ENABLE_TESTING command has been run, this command adds a test
      target to the current directory.  If ENABLE_TESTING has not been run,
      this command does nothing.  The tests are run by the testing subsystem
      by executing Exename with the specified arguments.  Exename can be
      either an executable built by this project or an arbitrary executable
      on the system (like tclsh).  The test will be run with the current
      working directory set to the CMakeList.txt files corresponding
      directory in the binary tree.
 
  aux_source_directory
      Find all source files in a directory.
 
        aux_source_directory(<dir> <variable>)
 
      Collects the names of all the source files in the specified directory
      and stores the list in the <variable> provided.  This command is
      intended to be used by projects that use explicit template
      instantiation.  Template instantiation files can be stored in a
      "Templates" subdirectory and collected automatically using this
      command to avoid manually listing all instantiations.
 
      It is tempting to use this command to avoid writing the list of source
      files for a library or executable target.  While this seems to work,
      there is no way for CMake to generate a build system that knows when a
      new source file has been added.  Normally the generated build system
      knows when it needs to rerun CMake because the CMakeLists.txt file is
      modified to add a new source.  When the source is just added to the
      directory without modifying this file, one would have to manually
      rerun CMake to generate a build system incorporating the new file.
 
  break
      Break from an enclosing foreach or while loop.
 
        break()
 
      Breaks from an enclosing foreach loop or while loop
 
  build_command
      Get the command line that will build this project.
 
        build_command(<variable> <makecommand>)
 
      Sets the given <variable> to a string containing the command that will
      build this project from the root of the build tree using the build
      tool given by <makecommand>.  <makecommand> should be msdev, nmake,
      make or one of the end user build tools.  This is useful for
      configuring testing systems.
 
  cmake_minimum_required
      Set the minimum required version of cmake for a project.
 
        cmake_minimum_required(VERSION major[.minor[.patch]]
                                [FATAL_ERROR])
 
      If the current version of CMake is lower than that required it will
      stop processing the project and report an error.  When a version
      higher than 2.4 is specified the command implicitly invokes
 
        cmake_policy(VERSION major[.minor[.patch]])
 
      which sets the cmake policy version level to the version specified.
      When version 2.4 or lower is given the command implicitly invokes
 
        cmake_policy(VERSION 2.4)
 
      which enables compatibility features for CMake 2.4 and lower.
 
      The FATAL_ERROR option is accepted but ignored by CMake 2.6 and
      higher.  It should be specified so CMake versions 2.4 and lower fail
      with an error instead of just a warning.
 
  cmake_policy
      Manage CMake Policy settings.
 
      As CMake evolves it is sometimes necessary to change existing behavior
      in order to fix bugs or improve implementations of existing features.
      The CMake Policy mechanism is designed to help keep existing projects
      building as new versions of CMake introduce changes in behavior.  Each
      new policy (behavioral change) is given an identifier of the form
      "CMP<NNNN>" where "<NNNN>" is an integer index.  Documentation
      associated with each policy describes the OLD and NEW behavior and the
      reason the policy was introduced.  Projects may set each policy to
      select the desired behavior.  When CMake needs to know which behavior
      to use it checks for a setting specified by the project.  If no
      setting is available the OLD behavior is assumed and a warning is
      produced requesting that the policy be set.
 
      The cmake_policy command is used to set policies to OLD or NEW
      behavior.  While setting policies individually is supported, we
      encourage projects to set policies based on CMake versions.
 
        cmake_policy(VERSION major.minor[.patch])
 
      Specify that the current CMake list file is written for the given
      version of CMake.  All policies introduced in the specified version or
      earlier will be set to use NEW behavior.  All policies introduced
      after the specified version will be reset to use OLD behavior with a
      warning.  This effectively requests behavior preferred as of a given
      CMake version and tells newer CMake versions to warn about their new
      policies.  The policy version specified must be at least 2.4 or the
      command will report an error.  In order to get compatibility features
      supporting versions earlier than 2.4 see documentation of policy
      CMP0001.
 
        cmake_policy(SET CMP<NNNN> NEW)
        cmake_policy(SET CMP<NNNN> OLD)
 
      Tell CMake to use the OLD or NEW behavior for a given policy.
      Projects depending on the old behavior of a given policy may silence a
      policy warning by setting the policy state to OLD.  Alternatively one
      may fix the project to work with the new behavior and set the policy
      state to NEW.
 
        cmake_policy(GET CMP<NNNN> <variable>)
 
      Check whether a given policy is set to OLD or NEW behavior.  The
      output variable value will be "OLD" or "NEW" if the policy is set, and
      empty otherwise.
 
      CMake keeps policy settings on a stack, so changes made by the
      cmake_policy command affect only the top of the stack.  A new entry on
      the policy stack is managed automatically for each subdirectory to
      protect its parents and siblings.  CMake also manages a new entry for
      scripts loaded by include() and find_package() commands except when
      invoked with the NO_POLICY_SCOPE option (see also policy CMP0011).
      The cmake_policy command provides an interface to manage custom
      entries on the policy stack:
 
        cmake_policy(PUSH)
        cmake_policy(POP)
 
      Each PUSH must have a matching POP to erase any changes.  This is
      useful to make temporary changes to policy settings.
 
      Functions and macros record policy settings when they are created and
      use the pre-record policies when they are invoked.  If the function or
      macro implementation sets policies, the changes automatically
      propagate up through callers until they reach the closest nested
      policy stack entry.
 
  configure_file
      Copy a file to another location and modify its contents.
 
        configure_file(InputFile OutputFile
                        [COPYONLY] [ESCAPE_QUOTES] [@ONLY])
 
      The Input and Output files have to have full paths.  This command
      replaces any variables in the input file referenced as ${VAR} or @VAR@
      with their values as determined by CMake.  If a variable is not
      defined, it will be replaced with nothing.  If COPYONLY is specified,
      then no variable expansion will take place.  If ESCAPE_QUOTES is
      specified then any substituted quotes will be C-style escaped.  The
      file will be configured with the current values of CMake variables.
      If @ONLY is specified, only variables of the form @VAR@ will be
      replaces and ${VAR} will be ignored.  This is useful for configuring
      scripts that use ${VAR}.  Any occurrences of #cmakedefine VAR will be
      replaced with either #define VAR or /* #undef VAR */ depending on the
      setting of VAR in CMake
 
  create_test_sourcelist
      Create a test driver and source list for building test programs.
 
        create_test_sourcelist(sourceListName driverName
                                test1 test2 test3
                                EXTRA_INCLUDE include.h
                                FUNCTION function)
 
      A test driver is a program that links together many small tests into a
      single executable.  This is useful when building static executables
      with large libraries to shrink the total required size.  The list of
      source files needed to build the test driver will be in
      sourceListName.  DriverName is the name of the test driver program.
      The rest of the arguments consist of a list of test source files, can
      be semicolon separated.  Each test source file should have a function
      in it that is the same name as the file with no extension (foo.cxx
      should have int foo(int, char*[]);) DriverName will be able to call
      each of the tests by name on the command line.  If EXTRA_INCLUDE is
      specified, then the next argument is included into the generated file.
      If FUNCTION is specified, then the next argument is taken as a
      function name that is passed a pointer to ac and av.  This can be used
      to add extra command line processing to each test.  The cmake variable
      CMAKE_TESTDRIVER_BEFORE_TESTMAIN can be set to have code that will be
      placed directly before calling the test main function.
      CMAKE_TESTDRIVER_AFTER_TESTMAIN can be set to have code that will be
      placed directly after the call to the test main function.
 
  define_property
      Define and document custom properties.
 
        define_property(<GLOBAL | DIRECTORY | TARGET | SOURCE |
                          TEST | VARIABLE | CACHED_VARIABLE>
                          PROPERTY <name> [INHERITED]
                          BRIEF_DOCS <brief-doc>
                          FULL_DOCS <full-doc>)
 
      Define one property in a scope for use with the set_property and
      get_property commands.  This is primarily useful to associate
      documentation with property names that may be retrieved with the
      get_property command.  The first argument determines the kind of scope
      in which the property should be used.  It must be one of the
      following:
 
        GLOBAL    = associated with the global namespace
        DIRECTORY = associated with one directory
        TARGET    = associated with one target
        SOURCE    = associated with one source file
        TEST      = associated with a test named with add_test command
        VARIABLE  = documents a CMake language variable
        CACHED_VARIABLE = documents a CMake cache variable
 
      Note that unlike set_property and get_property no actual scope needs
      to be given; only the kind of scope is important.
 
      The required PROPERTY option is immediately followed by the name of
      the property being defined.
 
      If the INHERITED option then the get_property command will chain up to
      the next higher scope when the requested property is not set in the
      scope given to the command.  DIRECTORY scope chains to GLOBAL.
      TARGET, SOURCE, and TEST chain to DIRECTORY.
 
      The BRIEF_DOCS and FULL_DOCS options are followed by strings to be
      associated with the property as its brief and full documentation.
      Corresponding options to the get_property command will retrieve the
      documentation.
 
  else
      Starts the else portion of an if block.
 
        else(expression)
 
      See the if command.
 
  elseif
      Starts the elseif portion of an if block.
 
        elseif(expression)
 
      See the if command.
 
  enable_language
      Enable a language (CXX/C/Fortran/etc)
 
        enable_language(languageName [OPTIONAL] )
 
      This command enables support for the named language in CMake.  This is
      the same as the project command but does not create any of the extra
      variables that are created by the project command.  Example languages
      are CXX, C, Fortran.
 
      If OPTIONAL is used, use the CMAKE_<languageName>_COMPILER_WORKS
      variable to check whether the language has been enabled successfully.
 
  enable_testing
      Enable testing for current directory and below.
 
        enable_testing()
 
      Enables testing for this directory and below.  See also the add_test
      command.  Note that ctest expects to find a test file in the build
      directory root.  Therefore, this command should be in the source
      directory root.

  execute_process
      Execute one or more child processes.
 
        execute_process(COMMAND <cmd1> [args1...]]
                        [COMMAND <cmd2> [args2...] [...]]
                        [WORKING_DIRECTORY <directory>]
                        [TIMEOUT <seconds>]
                        [RESULT_VARIABLE <variable>]
                        [OUTPUT_VARIABLE <variable>]
                        [ERROR_VARIABLE <variable>]
                        [INPUT_FILE <file>]
                        [OUTPUT_FILE <file>]
                        [ERROR_FILE <file>]
                        [OUTPUT_QUIET]
                        [ERROR_QUIET]
                        [OUTPUT_STRIP_TRAILING_WHITESPACE]
                        [ERROR_STRIP_TRAILING_WHITESPACE])
 
      Runs the given sequence of one or more commands with the standard
      output of each process piped to the standard input of the next.  A
      single standard error pipe is used for all processes.  If
      WORKING_DIRECTORY is given the named directory will be set as the
      current working directory of the child processes.  If TIMEOUT is given
      the child processes will be terminated if they do not finish in the
      specified number of seconds (fractions are allowed).  If
      RESULT_VARIABLE is given the variable will be set to contain the
      result of running the processes.  This will be an integer return code
      from the last child or a string describing an error condition.  If
      OUTPUT_VARIABLE or ERROR_VARIABLE are given the variable named will be
      set with the contents of the standard output and standard error pipes
      respectively.  If the same variable is named for both pipes their
      output will be merged in the order produced.  If INPUT_FILE,
      OUTPUT_FILE, or ERROR_FILE is given the file named will be attached to
      the standard input of the first process, standard output of the last
      process, or standard error of all processes respectively.  If
      OUTPUT_QUIET or ERROR_QUIET is given then the standard output or
      standard error results will be quietly ignored.  If more than one
      OUTPUT_* or ERROR_* option is given for the same pipe the precedence
      is not specified.  If no OUTPUT_* or ERROR_* options are given the
      output will be shared with the corresponding pipes of the CMake
      process itself.
 
      The execute_process command is a newer more powerful version of
      exec_program, but the old command has been kept for compatibility.
 
  export
      Export targets from the build tree for use by outside projects.
 
        export(TARGETS [target1 [target2 [...]]] [NAMESPACE <namespace>]
                [APPEND] FILE <filename>)
 
      Create a file <filename> that may be included by outside projects to
      import targets from the current project's build tree.  This is useful
      during cross-compiling to build utility executables that can run on
      the host platform in one project and then import them into another
      project being compiled for the target platform.  If the NAMESPACE
      option is given the <namespace> string will be prepended to all target
      names written to the file.  If the APPEND option is given the
      generated code will be appended to the file instead of overwriting it.
      If a library target is included in the export but a target to which it
      links is not included the behavior is unspecified.
 
      The file created by this command is specific to the build tree and
      should never be installed.  See the install(EXPORT) command to export
      targets from an installation tree.
 
  file
      File manipulation command.
 
        file(WRITE filename "message to write"... )
        file(APPEND filename "message to write"... )
        file(READ filename variable [LIMIT numBytes] [OFFSET offset] [HEX])
        file(STRINGS filename variable [LIMIT_COUNT num]
              [LIMIT_INPUT numBytes] [LIMIT_OUTPUT numBytes]
              [LENGTH_MINIMUM numBytes] [LENGTH_MAXIMUM numBytes]
              [NEWLINE_CONSUME] [REGEX regex]
              [NO_HEX_CONVERSION])
        file(GLOB variable [RELATIVE path] [globbing expressions]...)
        file(GLOB_RECURSE variable [RELATIVE path]
              [FOLLOW_SYMLINKS] [globbing expressions]...)
        file(REMOVE [file1 ...])
        file(REMOVE_RECURSE [file1 ...])
        file(MAKE_DIRECTORY [directory1 directory2 ...])
        file(RELATIVE_PATH variable directory file)
        file(TO_CMAKE_PATH path result)
        file(TO_NATIVE_PATH path result)
        file(DOWNLOAD url file [TIMEOUT timeout] [STATUS status] [LOG log])
 
      WRITE will write a message into a file called 'filename'.  It
      overwrites the file if it already exists, and creates the file if it
      does not exist.
 
      APPEND will write a message into a file same as WRITE, except it will
      append it to the end of the file
 
      READ will read the content of a file and store it into the variable.
      It will start at the given offset and read up to numBytes.  If the
      argument HEX is given, the binary data will be converted to
      hexadecimal representation and this will be stored in the variable.
 
      STRINGS will parse a list of ASCII strings from a file and store it in
      a variable.  Binary data in the file are ignored.  Carriage return
      (CR) characters are ignored.  It works also for Intel Hex and Motorola
      S-record files, which are automatically converted to binary format
      when reading them.  Disable this using NO_HEX_CONVERSION.
 
      LIMIT_COUNT sets the maximum number of strings to return.  LIMIT_INPUT
      sets the maximum number of bytes to read from the input file.
      LIMIT_OUTPUT sets the maximum number of bytes to store in the output
      variable.  LENGTH_MINIMUM sets the minimum length of a string to
      return.  Shorter strings are ignored.  LENGTH_MAXIMUM sets the maximum
      length of a string to return.  Longer strings are split into strings
      no longer than the maximum length.  NEWLINE_CONSUME allows newlines to
      be included in strings instead of terminating them.
 
      REGEX specifies a regular expression that a string must match to be
      returned.  Typical usage
 
        file(STRINGS myfile.txt myfile)
 
      stores a list in the variable "myfile" in which each item is a line
      from the input file.
 
      GLOB will generate a list of all files that match the globbing
      expressions and store it into the variable.  Globbing expressions are
      similar to regular expressions, but much simpler.  If RELATIVE flag is
      specified for an expression, the results will be returned as a
      relative path to the given path.
 
      Examples of globbing expressions include:
 
          *.cxx      - match all files with extension cxx
          *.vt?      - match all files with extension vta,...,vtz
          f[3-5].txt - match files f3.txt, f4.txt, f5.txt
 
      GLOB_RECURSE will generate a list similar to the regular GLOB, except
      it will traverse all the subdirectories of the matched directory and
      match the files.  Subdirectories that are symlinks are only traversed
      if FOLLOW_SYMLINKS is given or cmake policy CMP0009 is not set to NEW.
      See cmake --help-policy CMP0009 for more information.
 
      Examples of recursive globbing include:
 
          /dir/*.py  - match all python files in /dir and subdirectories
 
      MAKE_DIRECTORY will create the given directories, also if their parent
      directories don't exist yet
 
      REMOVE will remove the given files, also in subdirectories
 
      REMOVE_RECURSE will remove the given files and directories, also
      non-empty directories
 
      RELATIVE_PATH will determine relative path from directory to the given
      file.
 
      TO_CMAKE_PATH will convert path into a cmake style path with unix /.
      The input can be a single path or a system path like "$ENV{PATH}".
      Note the double quotes around the ENV call TO_CMAKE_PATH only takes
      one argument.
 
      TO_NATIVE_PATH works just like TO_CMAKE_PATH, but will convert from a
      cmake style path into the native path style \ for windows and / for
      UNIX.
 
      DOWNLOAD will download the given URL to the given file.  If LOG var is
      specified a log of the download will be put in var.  If STATUS var is
      specified the status of the operation will be put in var.  The status
      is returned in a list of length 2.  The first element is the numeric
      return value for the operation, and the second element is a string
      value for the error.  A 0 numeric error means no error in the
      operation.  If TIMEOUT time is specified, the operation will timeout
      after time seconds, time can be specified as a float.
 
 
  find_file
      Find the full path to a file.
 
          find_path(<VAR> name1 [path1 path2 ...])
 
      This is the short-hand signature for the command that is sufficient in
      many cases.  It is the same as find_path(<VAR> name1 [PATHS path1
      path2 ...])
 
          find_path(
                    <VAR>
                    name | NAMES name1 [name2 ...]
                    [HINTS path1 [path2 ... ENV var]]
                    [PATHS path1 [path2 ... ENV var]]
                    [PATH_SUFFIXES suffix1 [suffix2 ...]]
                    [DOC "cache documentation string"]
                    [NO_DEFAULT_PATH]
                    [NO_CMAKE_ENVIRONMENT_PATH]
                    [NO_CMAKE_PATH]
                    [NO_SYSTEM_ENVIRONMENT_PATH]
                    [NO_CMAKE_SYSTEM_PATH]
                    [CMAKE_FIND_ROOT_PATH_BOTH |
                    ONLY_CMAKE_FIND_ROOT_PATH |
                    NO_CMAKE_FIND_ROOT_PATH]
                  )
 
      This command is used to find a full path to named file.  A cache entry
      named by <VAR> is created to store the result of this command.  If the
      full path to a file is found the result is stored in the variable and
      the search will not be repeated unless the variable is cleared.  If
      nothing is found, the result will be <VAR>-NOTFOUND, and the search
      will be attempted again the next time find_path is invoked with the
      same variable.  The name of the full path to a file that is searched
      for is specified by the names listed after the NAMES argument.
      Additional search locations can be specified after the PATHS argument.
      If ENV var is found in the HINTS or PATHS section the environment
      variable var will be read and converted from a system environment
      variable to a cmake style list of paths.  For example ENV PATH would
      be a way to list the system path variable.  The argument after DOC
      will be used for the documentation string in the cache.  PATH_SUFFIXES
      specifies additional subdirectories to check below each search path.
 
      If NO_DEFAULT_PATH is specified, then no additional paths are added to
      the search.  If NO_DEFAULT_PATH is not specified, the search process
      is as follows:
 
      1.  Search paths specified in cmake-specific cache variables.  These
      are intended to be used on the command line with a -DVAR=value.  This
      can be skipped if NO_CMAKE_PATH is passed.
 
          <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_INCLUDE_PATH
          CMAKE_FRAMEWORK_PATH
 
      2.  Search paths specified in cmake-specific environment variables.
      These are intended to be set in the user's shell configuration.  This
      can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
 
          <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_INCLUDE_PATH
          CMAKE_FRAMEWORK_PATH
 
      3.  Search the paths specified by the HINTS option.  These should be
      paths computed by system introspection, such as a hint provided by the
      location of another item already found.  Hard-coded guesses should be
      specified with the PATHS option.
 
      4.  Search the standard system environment variables.  This can be
      skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.
 
          PATH
          INCLUDE
 
      5.  Search cmake variables defined in the Platform files for the
      current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
      passed.
 
          <prefix>/include for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_INCLUDE_PATH
          CMAKE_SYSTEM_FRAMEWORK_PATH
 
      6.  Search the paths specified by the PATHS option or in the
      short-hand version of the command.  These are typically hard-coded
      guesses.
 
      On Darwin or systems supporting OS X Frameworks, the cmake variable
      CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:
 
          "FIRST"  - Try to find frameworks before standard
                    libraries or headers. This is the default on Darwin.
          "LAST"  - Try to find frameworks after standard
                    libraries or headers.
          "ONLY"  - Only try to find frameworks.
          "NEVER". - Never try to find frameworks.
 
      On Darwin or systems supporting OS X Application Bundles, the cmake
      variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
      following:
 
          "FIRST"  - Try to find application bundles before standard
                    programs. This is the default on Darwin.
          "LAST"  - Try to find application bundles after standard
                    programs.
          "ONLY"  - Only try to find application bundles.
          "NEVER". - Never try to find application bundles.
 
      The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
      directories to be prepended to all other search directories.  This
      effectively "re-roots" the entire search under given locations.  By
      default it is empty.  It is especially useful when cross-compiling to
      point to the root directory of the target environment and CMake will
      search there too.  By default at first the directories listed in
      CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
      searched.  The default behavior can be adjusted by setting
      CMAKE_FIND_ROOT_PATH_MODE_INCLUDE.  This behavior can be manually
      overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
      the search order will be as described above.  If
      NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
      used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
      directories will be searched.
 
      The default search order is designed to be most-specific to
      least-specific for common use cases.  Projects may override the order
      by simply calling the command multiple times and using the NO_*
      options:
 
          find_path(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_path(<VAR> NAMES name)
 
      Once one of the calls succeeds the result variable will be set and
      stored in the cache so that no call will search again.
 
  find_library
      Find a library.
 
          find_library(<VAR> name1 [path1 path2 ...])
 
      This is the short-hand signature for the command that is sufficient in
      many cases.  It is the same as find_library(<VAR> name1 [PATHS path1
      path2 ...])
 
          find_library(
                    <VAR>
                    name | NAMES name1 [name2 ...]
                    [HINTS path1 [path2 ... ENV var]]
                    [PATHS path1 [path2 ... ENV var]]
                    [PATH_SUFFIXES suffix1 [suffix2 ...]]
                    [DOC "cache documentation string"]
                    [NO_DEFAULT_PATH]
                    [NO_CMAKE_ENVIRONMENT_PATH]
                    [NO_CMAKE_PATH]
                    [NO_SYSTEM_ENVIRONMENT_PATH]
                    [NO_CMAKE_SYSTEM_PATH]
                    [CMAKE_FIND_ROOT_PATH_BOTH |
                    ONLY_CMAKE_FIND_ROOT_PATH |
                    NO_CMAKE_FIND_ROOT_PATH]
                  )
 
      This command is used to find a library.  A cache entry named by <VAR>
      is created to store the result of this command.  If the library is
      found the result is stored in the variable and the search will not be
      repeated unless the variable is cleared.  If nothing is found, the
      result will be <VAR>-NOTFOUND, and the search will be attempted again
      the next time find_library is invoked with the same variable.  The
      name of the library that is searched for is specified by the names
      listed after the NAMES argument.  Additional search locations can be
      specified after the PATHS argument.  If ENV var is found in the HINTS
      or PATHS section the environment variable var will be read and
      converted from a system environment variable to a cmake style list of
      paths.  For example ENV PATH would be a way to list the system path
      variable.  The argument after DOC will be used for the documentation
      string in the cache.  PATH_SUFFIXES specifies additional
      subdirectories to check below each search path.
 
      If NO_DEFAULT_PATH is specified, then no additional paths are added to
      the search.  If NO_DEFAULT_PATH is not specified, the search process
      is as follows:
 
      1.  Search paths specified in cmake-specific cache variables.  These
      are intended to be used on the command line with a -DVAR=value.  This
      can be skipped if NO_CMAKE_PATH is passed.
 
          <prefix>/lib for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_LIBRARY_PATH
          CMAKE_FRAMEWORK_PATH
 
      2.  Search paths specified in cmake-specific environment variables.
      These are intended to be set in the user's shell configuration.  This
      can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
 
          <prefix>/lib for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_LIBRARY_PATH
          CMAKE_FRAMEWORK_PATH
 
      3.  Search the paths specified by the HINTS option.  These should be
      paths computed by system introspection, such as a hint provided by the
      location of another item already found.  Hard-coded guesses should be
      specified with the PATHS option.
 
      4.  Search the standard system environment variables.  This can be
      skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.
 
          PATH
          LIB
 
      5.  Search cmake variables defined in the Platform files for the
      current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
      passed.
 
          <prefix>/lib for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_LIBRARY_PATH
          CMAKE_SYSTEM_FRAMEWORK_PATH
 
      6.  Search the paths specified by the PATHS option or in the
      short-hand version of the command.  These are typically hard-coded
      guesses.
 
      On Darwin or systems supporting OS X Frameworks, the cmake variable
      CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:
 
          "FIRST"  - Try to find frameworks before standard
                    libraries or headers. This is the default on Darwin.
          "LAST"  - Try to find frameworks after standard
                    libraries or headers.
          "ONLY"  - Only try to find frameworks.
          "NEVER". - Never try to find frameworks.
 
      On Darwin or systems supporting OS X Application Bundles, the cmake
      variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
      following:
 
          "FIRST"  - Try to find application bundles before standard
                    programs. This is the default on Darwin.
          "LAST"  - Try to find application bundles after standard
                    programs.
          "ONLY"  - Only try to find application bundles.
          "NEVER". - Never try to find application bundles.
 
      The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
      directories to be prepended to all other search directories.  This
      effectively "re-roots" the entire search under given locations.  By
      default it is empty.  It is especially useful when cross-compiling to
      point to the root directory of the target environment and CMake will
      search there too.  By default at first the directories listed in
      CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
      searched.  The default behavior can be adjusted by setting
      CMAKE_FIND_ROOT_PATH_MODE_LIBRARY.  This behavior can be manually
      overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
      the search order will be as described above.  If
      NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
      used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
      directories will be searched.
 
      The default search order is designed to be most-specific to
      least-specific for common use cases.  Projects may override the order
      by simply calling the command multiple times and using the NO_*
      options:
 
          find_library(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_library(<VAR> NAMES name)
 
      Once one of the calls succeeds the result variable will be set and
      stored in the cache so that no call will search again.
 
      If the library found is a framework, then VAR will be set to the full
      path to the framework <fullPath>/A.framework.  When a full path to a
      framework is used as a library, CMake will use a -framework A, and a
      -F<fullPath> to link the framework to the target.
 
  find_package
      Load settings for an external project.
 
        find_package(<package> [version] [EXACT] [QUIET]
                      [[REQUIRED|COMPONENTS] [components...]]
                      [NO_POLICY_SCOPE])
 
      Finds and loads settings from an external project.  <package>_FOUND
      will be set to indicate whether the package was found.  When the
      package is found package-specific information is provided through
      variables documented by the package itself.  The QUIET option disables
      messages if the package cannot be found.  The REQUIRED option stops
      processing with an error message if the package cannot be found.  A
      package-specific list of components may be listed after the REQUIRED
      option or after the COMPONENTS option if no REQUIRED option is given.
      The [version] argument requests a version with which the package found
      should be compatible (format is major[.minor[.patch[.tweak]]]).  The
      EXACT option requests that the version be matched exactly.  If no
      [version] is given to a recursive invocation inside a find-module, the
      [version] and EXACT arguments are forwarded automatically from the
      outer call.  Version support is currently provided only on a
      package-by-package basis (details below).
 
      User code should generally look for packages using the above simple
      signature.  The remainder of this command documentation specifies the
      full command signature and details of the search process.  Project
      maintainers wishing to provide a package to be found by this command
      are encouraged to read on.
 
      The command has two modes by which it searches for packages: "Module"
      mode and "Config" mode.  Module mode is available when the command is
      invoked with the above reduced signature.  CMake searches for a file
      called "Find<package>.cmake" in the CMAKE_MODULE_PATH followed by the
      CMake installation.  If the file is found, it is read and processed by
      CMake.  It is responsible for finding the package, checking the
      version, and producing any needed messages.  Many find-modules provide
      limited or no support for versioning; check the module documentation.
      If no module is found the command proceeds to Config mode.
 
      The complete Config mode command signature is:
 
        find_package(<package> [version] [EXACT] [QUIET]
                      [[REQUIRED|COMPONENTS] [components...]] [NO_MODULE]
                      [NO_POLICY_SCOPE]
                      [NAMES name1 [name2 ...]]
                      [CONFIGS config1 [config2 ...]]
                      [HINTS path1 [path2 ... ]]
                      [PATHS path1 [path2 ... ]]
                      [PATH_SUFFIXES suffix1 [suffix2 ...]]
                      [NO_DEFAULT_PATH]
                      [NO_CMAKE_ENVIRONMENT_PATH]
                      [NO_CMAKE_PATH]
                      [NO_SYSTEM_ENVIRONMENT_PATH]
                      [NO_CMAKE_BUILDS_PATH]
                      [NO_CMAKE_SYSTEM_PATH]
                      [CMAKE_FIND_ROOT_PATH_BOTH |
                      ONLY_CMAKE_FIND_ROOT_PATH |
                      NO_CMAKE_FIND_ROOT_PATH])
 
      The NO_MODULE option may be used to skip Module mode explicitly.  It
      is also implied by use of options not specified in the reduced
      signature.
 
      Config mode attempts to locate a configuration file provided by the
      package to be found.  A cache entry called <package>_DIR is created to
      hold the directory containing the file.  By default the command
      searches for a package with the name <package>.  If the NAMES option
      is given the names following it are used instead of <package>.  The
      command searches for a file called "<name>Config.cmake" or
      "<lower-case-name>-config.cmake" for each name specified.  A
      replacement set of possible configuration file names may be given
      using the CONFIGS option.  The search procedure is specified below.
      Once found, the configuration file is read and processed by CMake.
      Since the file is provided by the package it already knows the
      location of package contents.  The full path to the configuration file
      is stored in the cmake variable <package>_CONFIG.
 
      If the package configuration file cannot be found CMake will generate
      an error describing the problem unless the QUIET argument is
      specified.  If REQUIRED is specified and the package is not found a
      fatal error is generated and the configure step stops executing.  If
      <package>_DIR has been set to a directory not containing a
      configuration file CMake will ignore it and search from scratch.
 
      When the [version] argument is given Config mode will only find a
      version of the package that claims compatibility with the requested
      version (format is major[.minor[.patch[.tweak]]]).  If the EXACT
      option is given only a version of the package claiming an exact match
      of the requested version may be found.  CMake does not establish any
      convention for the meaning of version numbers.  Package version
      numbers are checked by "version" files provided by the packages
      themselves.  For a candidate package confguration file
      "<config-file>.cmake" the corresponding version file is located next
      to it and named either "<config-file>-version.cmake" or
      "<config-file>Version.cmake".  If no such version file is available
      then the configuration file is assumed to not be compatible with any
      requested version.  When a version file is found it is loaded to check
      the requested version number.  The version file is loaded in a nested
      scope in which the following variables have been defined:
 
        PACKAGE_FIND_NAME          = the <package> name
        PACKAGE_FIND_VERSION      = full requested version string
        PACKAGE_FIND_VERSION_MAJOR = major version if requested, else 0
        PACKAGE_FIND_VERSION_MINOR = minor version if requested, else 0
        PACKAGE_FIND_VERSION_PATCH = patch version if requested, else 0
        PACKAGE_FIND_VERSION_TWEAK = tweak version if requested, else 0
        PACKAGE_FIND_VERSION_COUNT = number of version components, 0 to 4
 
      The version file checks whether it satisfies the requested version and
      sets these variables:
 
        PACKAGE_VERSION            = full provided version string
        PACKAGE_VERSION_EXACT      = true if version is exact match
        PACKAGE_VERSION_COMPATIBLE = true if version is compatible
        PACKAGE_VERSION_UNSUITABLE = true if unsuitable as any version
 
      These variables are checked by the find_package command to determine
      whether the configuration file provides an acceptable version.  They
      are not available after the find_package call returns.  If the version
      is acceptable the following variables are set:
 
        <package>_VERSION      = full provided version string
        <package>_VERSION_MAJOR = major version if provided, else 0
        <package>_VERSION_MINOR = minor version if provided, else 0
        <package>_VERSION_PATCH = patch version if provided, else 0
        <package>_VERSION_TWEAK = tweak version if provided, else 0
        <package>_VERSION_COUNT = number of version components, 0 to 4
 
      and the corresponding package configuration file is loaded.  When
      multiple package configuration files are available whose version files
      claim compatibility with the version requested it is unspecified which
      one is chosen.  No attempt is made to choose a highest or closest
      version number.
 
      Config mode provides an elaborate interface and search procedure.
      Much of the interface is provided for completeness and for use
      internally by find-modules loaded by Module mode.  Most user code
      should simply call
 
        find_package(<package> [major[.minor]] [EXACT] [REQUIRED|QUIET])
 
      in order to find a package.  Package maintainers providing CMake
      package configuration files are encouraged to name and install them
      such that the procedure outlined below will find them without
      requiring use of additional options.
 
      CMake constructs a set of possible installation prefixes for the
      package.  Under each prefix several directories are searched for a
      configuration file.  The tables below show the directories searched.
      Each entry is meant for installation trees following Windows (W), UNIX
      (U), or Apple (A) conventions.
 
        <prefix>/                                              (W)
        <prefix>/(cmake|CMake)/                                (W)
        <prefix>/<name>*/                                      (W)
        <prefix>/<name>*/(cmake|CMake)/                        (W)
        <prefix>/(share|lib)/cmake/<name>*/                    (U)
        <prefix>/(share|lib)/<name>*/                          (U)
        <prefix>/(share|lib)/<name>*/(cmake|CMake)/            (U)
 
      On systems supporting OS X Frameworks and Application Bundles the
      following directories are searched for frameworks or bundles
      containing a configuration file:
 
        <prefix>/<name>.framework/Resources/                    (A)
        <prefix>/<name>.framework/Resources/CMake/              (A)
        <prefix>/<name>.framework/Versions/*/Resources/        (A)
        <prefix>/<name>.framework/Versions/*/Resources/CMake/  (A)
        <prefix>/<name>.app/Contents/Resources/                (A)
        <prefix>/<name>.app/Contents/Resources/CMake/          (A)
 
      In all cases the <name> is treated as case-insensitive and corresponds
      to any of the names specified (<package> or names given by NAMES).  If
      PATH_SUFFIXES is specified the suffixes are appended to each (W) or
      (U) directory entry one-by-one.
 
      This set of directories is intended to work in cooperation with
      projects that provide configuration files in their installation trees.
      Directories above marked with (W) are intended for installations on
      Windows where the prefix may point at the top of an application's
      installation directory.  Those marked with (U) are intended for
      installations on UNIX platforms where the prefix is shared by multiple
      packages.  This is merely a convention, so all (W) and (U) directories
      are still searched on all platforms.  Directories marked with (A) are
      intended for installations on Apple platforms.  The cmake variables
      CMAKE_FIND_FRAMEWORK and CMAKE_FIND_APPBUNDLE determine the order of
      preference as specified below.
 
      The set of installation prefixes is constructed using the following
      steps.  If NO_DEFAULT_PATH is specified all NO_* options are enabled.
 
      1.  Search paths specified in cmake-specific cache variables.  These
      are intended to be used on the command line with a -DVAR=value.  This
      can be skipped if NO_CMAKE_PATH is passed.
 
          CMAKE_PREFIX_PATH
          CMAKE_FRAMEWORK_PATH
          CMAKE_APPBUNDLE_PATH
 
      2.  Search paths specified in cmake-specific environment variables.
      These are intended to be set in the user's shell configuration.  This
      can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
 
          CMAKE_PREFIX_PATH
          CMAKE_FRAMEWORK_PATH
          CMAKE_APPBUNDLE_PATH
 
      3.  Search paths specified by the HINTS option.  These should be paths
      computed by system introspection, such as a hint provided by the
      location of another item already found.  Hard-coded guesses should be
      specified with the PATHS option.
 
      4.  Search the standard system environment variables.  This can be
      skipped if NO_SYSTEM_ENVIRONMENT_PATH is passed.  Path entries ending
      in "/bin" or "/sbin" are automatically converted to their parent
      directories.
 
          PATH
 
      5.  Search project build trees recently configured in a CMake GUI.
      This can be skipped if NO_CMAKE_BUILDS_PATH is passed.  It is intended
      for the case when a user is building multiple dependent projects one
      after another.
 
      6.  Search cmake variables defined in the Platform files for the
      current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
      passed.
 
          CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_FRAMEWORK_PATH
          CMAKE_SYSTEM_APPBUNDLE_PATH
 
      7.  Search paths specified by the PATHS option.  These are typically
      hard-coded guesses.
 
      On Darwin or systems supporting OS X Frameworks, the cmake variable
      CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:
 
          "FIRST"  - Try to find frameworks before standard
                    libraries or headers. This is the default on Darwin.
          "LAST"  - Try to find frameworks after standard
                    libraries or headers.
          "ONLY"  - Only try to find frameworks.
          "NEVER". - Never try to find frameworks.
 
      On Darwin or systems supporting OS X Application Bundles, the cmake
      variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
      following:
 
          "FIRST"  - Try to find application bundles before standard
                    programs. This is the default on Darwin.
          "LAST"  - Try to find application bundles after standard
                    programs.
          "ONLY"  - Only try to find application bundles.
          "NEVER". - Never try to find application bundles.
 
      The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
      directories to be prepended to all other search directories.  This
      effectively "re-roots" the entire search under given locations.  By
      default it is empty.  It is especially useful when cross-compiling to
      point to the root directory of the target environment and CMake will
      search there too.  By default at first the directories listed in
      CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
      searched.  The default behavior can be adjusted by setting
      CMAKE_FIND_ROOT_PATH_MODE_PACKAGE.  This behavior can be manually
      overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
      the search order will be as described above.  If
      NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
      used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
      directories will be searched.
 
      The default search order is designed to be most-specific to
      least-specific for common use cases.  Projects may override the order
      by simply calling the command multiple times and using the NO_*
      options:
 
          find_package(<package> PATHS paths... NO_DEFAULT_PATH)
          find_package(<package>)
 
      Once one of the calls succeeds the result variable will be set and
      stored in the cache so that no call will search again.
 
      See the cmake_policy() command documentation for discussion of the
      NO_POLICY_SCOPE option.
 
  find_path
      Find the directory containing a file.
 
          find_path(<VAR> name1 [path1 path2 ...])
 
      This is the short-hand signature for the command that is sufficient in
      many cases.  It is the same as find_path(<VAR> name1 [PATHS path1
      path2 ...])
 
          find_path(
                    <VAR>
                    name | NAMES name1 [name2 ...]
                    [HINTS path1 [path2 ... ENV var]]

      This command is used to find a directory containing the named file.  A
      cache entry named by <VAR> is created to store the result of this
      command.  If the file in a directory is found the result is stored in
      the variable and the search will not be repeated unless the variable
      is cleared.  If nothing is found, the result will be <VAR>-NOTFOUND,
      and the search will be attempted again the next time find_path is
      invoked with the same variable.  The name of the file in a directory
      that is searched for is specified by the names listed after the NAMES
      argument.  Additional search locations can be specified after the
      PATHS argument.  If ENV var is found in the HINTS or PATHS section the
      environment variable var will be read and converted from a system
      environment variable to a cmake style list of paths.  For example ENV
      PATH would be a way to list the system path variable.  The argument
      after DOC will be used for the documentation string in the cache.
      PATH_SUFFIXES specifies additional subdirectories to check below each
      search path.
 
      If NO_DEFAULT_PATH is specified, then no additional paths are added to
      the search.  If NO_DEFAULT_PATH is not specified, the search process
      is as follows:
 
      1.  Search paths specified in cmake-specific cache variables.  These
      are intended to be used on the command line with a -DVAR=value.  This
      can be skipped if NO_CMAKE_PATH is passed.
 
          <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_INCLUDE_PATH
          CMAKE_FRAMEWORK_PATH
 
      2.  Search paths specified in cmake-specific environment variables.
      These are intended to be set in the user's shell configuration.  This
      can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
 
          <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_INCLUDE_PATH
          CMAKE_FRAMEWORK_PATH
 
      3.  Search the paths specified by the HINTS option.  These should be
      paths computed by system introspection, such as a hint provided by the
      location of another item already found.  Hard-coded guesses should be
      specified with the PATHS option.
 
      4.  Search the standard system environment variables.  This can be
      skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.
 
          PATH
          INCLUDE
 
      5.  Search cmake variables defined in the Platform files for the
      current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
      passed.
 
          <prefix>/include for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_INCLUDE_PATH
          CMAKE_SYSTEM_FRAMEWORK_PATH
 
      6.  Search the paths specified by the PATHS option or in the
      short-hand version of the command.  These are typically hard-coded
      guesses.
 
      On Darwin or systems supporting OS X Frameworks, the cmake variable
      CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:
 
          "FIRST"  - Try to find frameworks before standard
                    libraries or headers. This is the default on Darwin.
          "LAST"  - Try to find frameworks after standard
                    libraries or headers.
          "ONLY"  - Only try to find frameworks.
          "NEVER". - Never try to find frameworks.
 
      On Darwin or systems supporting OS X Application Bundles, the cmake
      variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
      following:
 
          "FIRST"  - Try to find application bundles before standard
                    programs. This is the default on Darwin.
          "LAST"  - Try to find application bundles after standard
                    programs.
          "ONLY"  - Only try to find application bundles.
          "NEVER". - Never try to find application bundles.
 
      The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
      directories to be prepended to all other search directories.  This
      effectively "re-roots" the entire search under given locations.  By
      default it is empty.  It is especially useful when cross-compiling to
      point to the root directory of the target environment and CMake will
      search there too.  By default at first the directories listed in
      CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
      searched.  The default behavior can be adjusted by setting
      CMAKE_FIND_ROOT_PATH_MODE_INCLUDE.  This behavior can be manually
      overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
      the search order will be as described above.  If
      NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
      used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
      directories will be searched.
 
      The default search order is designed to be most-specific to
      least-specific for common use cases.  Projects may override the order
      by simply calling the command multiple times and using the NO_*
      options:
 
          find_path(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_path(<VAR> NAMES name)
 
      Once one of the calls succeeds the result variable will be set and
      stored in the cache so that no call will search again.
 
      When searching for frameworks, if the file is specified as A/b.h, then
      the framework search will look for A.framework/Headers/b.h.  If that
      is found the path will be set to the path to the framework.  CMake
      will convert this to the correct -F option to include the file.
 
  find_program
      Find an executable program.
 
          find_program(<VAR> name1 [path1 path2 ...])
 
      This is the short-hand signature for the command that is sufficient in
      many cases.  It is the same as find_program(<VAR> name1 [PATHS path1
      path2 ...])

                  )
 
      This command is used to find a program.  A cache entry named by <VAR>
      is created to store the result of this command.  If the program is
      found the result is stored in the variable and the search will not be
      repeated unless the variable is cleared.  If nothing is found, the
      result will be <VAR>-NOTFOUND, and the search will be attempted again
      the next time find_program is invoked with the same variable.  The
      name of the program that is searched for is specified by the names
      listed after the NAMES argument.  Additional search locations can be
      specified after the PATHS argument.  If ENV var is found in the HINTS
      or PATHS section the environment variable var will be read and
      converted from a system environment variable to a cmake style list of
      paths.  For example ENV PATH would be a way to list the system path
      variable.  The argument after DOC will be used for the documentation
      string in the cache.  PATH_SUFFIXES specifies additional
      subdirectories to check below each search path.

  fltk_wrap_ui
      Create FLTK user interfaces Wrappers.
 
        fltk_wrap_ui(resultingLibraryName source1
                      source2 ... sourceN )
 
      Produce .h and .cxx files for all the .fl and .fld files listed.  The
      resulting .h and .cxx files will be added to a variable named
      resultingLibraryName_FLTK_UI_SRCS which should be added to your
      library.
 
  foreach
      Evaluate a group of commands for each value in a list.
 
        foreach(loop_var arg1 arg2 ...)
          COMMAND1(ARGS ...)
          COMMAND2(ARGS ...)
          ...
        endforeach(loop_var)
        foreach(loop_var RANGE total)
        foreach(loop_var RANGE start stop [step])
 
      All commands between foreach and the matching endforeach are recorded
      without being invoked.  Once the endforeach is evaluated, the recorded
      list of commands is invoked once for each argument listed in the
      original foreach command.  Before each iteration of the loop
      "${loop_var}" will be set as a variable with the current value in the
      list.
 
      Foreach can also iterate over a generated range of numbers.  There are
      three types of this iteration:
 
      * When specifying single number, the range will have elements 0 to
      "total".
 
      * When specifying two numbers, the range will have elements from the
      first number to the second number.
 
      * The third optional number is the increment used to iterate from the
      first number to the second number.
 
  function
      Start recording a function for later invocation as a command.
 
        function(<name> [arg1 [arg2 [arg3 ...]]])
          COMMAND1(ARGS ...)
          COMMAND2(ARGS ...)
          ...
        endfunction(<name>)
 
      Define a function named <name> that takes arguments named arg1 arg2
      arg3 (...).  Commands listed after function, but before the matching
      endfunction, are not invoked until the function is invoked.  When it
      is invoked, the commands recorded in the function are first modified
      by replacing formal parameters (${arg1}) with the arguments passed,
      and then invoked as normal commands.  In addition to referencing the
      formal parameters you can reference the variable ARGC which will be
      set to the number of arguments passed into the function as well as
      ARGV0 ARGV1 ARGV2 ...  which will have the actual values of the
      arguments passed in.  This facilitates creating functions with
      optional arguments.  Additionally ARGV holds the list of all arguments
      given to the function and ARGN holds the list of argument pass the
      last expected argument.
 
      See the cmake_policy() command documentation for the behavior of
      policies inside functions.
 
  get_cmake_property
      Get a property of the CMake instance.
 
        get_cmake_property(VAR property)
 
      Get a property from the CMake instance.  The value of the property is
      stored in the variable VAR.  If the property is not found, CMake will
      report an error.  Some supported properties include: VARIABLES,
      CACHE_VARIABLES, COMMANDS, MACROS, and COMPONENTS.
 
  get_directory_property
      Get a property of the directory.
 
        get_directory_property(VAR [DIRECTORY dir] property)
 
      Get a property from the Directory.  The value of the property is
      stored in the variable VAR.  If the property is not found, CMake will
      report an error.  The properties include: VARIABLES, CACHE_VARIABLES,
      COMMANDS, MACROS, INCLUDE_DIRECTORIES, LINK_DIRECTORIES, DEFINITIONS,
      INCLUDE_REGULAR_EXPRESSION, LISTFILE_STACK, PARENT_DIRECTORY, and
      DEFINITION varname.  If the DIRECTORY argument is provided then the
      property of the provided directory will be retrieved instead of the
      current directory.  You can only get properties of a directory during
      or after it has been traversed by cmake.
 
  get_filename_component
      Get a specific component of a full filename.
 
        get_filename_component(VarName FileName
                                PATH|ABSOLUTE|NAME|EXT|NAME_WE
                                [CACHE])
 
      Set VarName to be the path (PATH), file name (NAME), file extension
      (EXT), file name without extension (NAME_WE) of FileName, or the full
      absolute (ABSOLUTE) file name without symlinks.  Note that the path is
      converted to Unix slashes format and has no trailing slashes.  The
      longest file extension is always considered.  If the optional CACHE
      argument is specified, the result variable is added to the cache.
 
        get_filename_component(VarName FileName
                                PROGRAM [PROGRAM_ARGS ArgVar]
                                [CACHE])
 
      The program in FileName will be found in the system search path or
      left as a full path.  If PROGRAM_ARGS is present with PROGRAM, then
      any command-line arguments present in the FileName string are split
      from the program name and stored in ArgVar.  This is used to separate
      a program name from its arguments in a command line string.
 
  get_property
      Get a property.
 
        get_property(<variable>
                      <GLOBAL            |
                      DIRECTORY [dir]    |
                      TARGET    <target> |
                      SOURCE    <source> |
                      TEST      <test>  |
                      VARIABLE>
                      PROPERTY <name>
                      [SET | DEFINED | BRIEF_DOCS | FULL_DOCS])
 
      Get one property from one object in a scope.  The first argument
      specifies the variable in which to store the result.  The second
      argument determines the scope from which to get the property.  It must
      be one of the following:
 
      GLOBAL scope is unique and does not accept a name.
 
      DIRECTORY scope defaults to the current directory but another
      directory (already processed by CMake) may be named by full or
      relative path.
 
      TARGET scope must name one existing target.
 
      SOURCE scope must name one source file.
 
      TEST scope must name one existing test.
 
      VARIABLE scope is unique and does not accept a name.
 
      The required PROPERTY option is immediately followed by the name of
      the property to get.  If the property is not set an empty value is
      returned.  If the SET option is given the variable is set to a boolean
      value indicating whether the property has been set.  If the DEFINED
      option is given the variable is set to a boolean value indicating
      whether the property has been defined such as with define_property.
      If BRIEF_DOCS or FULL_DOCS is given then the variable is set to a
      string containing documentation for the requested property.  If
      documentation is requested for a property that has not been defined
      NOTFOUND is returned.
 
  get_source_file_property
      Get a property for a source file.
 
        get_source_file_property(VAR file property)
 
      Get a property from a source file.  The value of the property is
      stored in the variable VAR.  If the property is not found, VAR will be
      set to "NOTFOUND".  Use set_source_files_properties to set property
      values.  Source file properties usually control how the file is built.
      One property that is always there is LOCATION
 
  get_target_property
      Get a property from a target.
 
        get_target_property(VAR target property)
 
      Get a property from a target.  The value of the property is stored in
      the variable VAR.  If the property is not found, VAR will be set to
      "NOTFOUND".  Use set_target_properties to set property values.
      Properties are usually used to control how a target is built, but some
      query the target instead.  This command can get properties for any
      target so far created.  The targets do not need to be in the current
      CMakeLists.txt file.
 
  get_test_property
      Get a property of the test.
 
        get_test_property(test VAR property)
 
      Get a property from the Test.  The value of the property is stored in
      the variable VAR.  If the property is not found, CMake will report an
      error.  For a list of standard properties you can type cmake
      --help-property-list

          # else section.
          COMMAND1(ARGS ...)
          COMMAND2(ARGS ...)
          ...
        endif(expression)
 
      Evaluates the given expression.  If the result is true, the commands
      in the THEN section are invoked.  Otherwise, the commands in the else
      section are invoked.  The elseif and else sections are optional.  You
      may have multiple elseif clauses.  Note that the same expression must
      be given to if, and endif.  Long expressions can be used and the order
      or precedence is that the EXISTS, COMMAND, and DEFINED operators will
      be evaluated first.  Then any EQUAL, LESS, GREATER, STRLESS,
      STRGREATER, STREQUAL, MATCHES will be evaluated.  Then NOT operators
      and finally AND, OR operators will be evaluated.  Possible expressions
      are:
 
        if(variable)
 
      True if the variable's value is not empty, 0, N, NO, OFF, FALSE,
      NOTFOUND, or <variable>-NOTFOUND.
 
        if(NOT variable)

      True if the given name is an existing target, built or imported.
 
        if(EXISTS file-name)
        if(EXISTS directory-name)
 
      True if the named file or directory exists.  Behavior is well-defined
      only for full paths.
 
        if(file1 IS_NEWER_THAN file2)
 
      True if file1 is newer than file2 or if one of the two files doesn't
      exist.  Behavior is well-defined only for full paths.
 
        if(IS_DIRECTORY directory-name)
 
      True if the given name is a directory.  Behavior is well-defined only
      for full paths.
 
        if(IS_ABSOLUTE path)
 
      True if the given path is an absolute path.
 
          if(variable MATCHES regex)
        if(string MATCHES regex)

      (or greater, or equal) than the string on the right.
 
        if(version1 VERSION_LESS version2)
        if(version1 VERSION_EQUAL version2)
        if(version1 VERSION_GREATER version2)
 
      Component-wise integer version number comparison (version format is
      major[.minor[.patch[.tweak]]]).
 
        if(DEFINED variable)
 
      True if the given variable is defined.  It does not matter if the
      variable is true or false just if it has been set.
 
  include
      Read CMake listfile code from the given file.
 
        include(<file|module> [OPTIONAL] [RESULT_VARIABLE <VAR>]
                              [NO_POLICY_SCOPE])
 
      Reads CMake listfile code from the given file.  Commands in the file
      are processed immediately as if they were written in place of the
      include command.  If OPTIONAL is present, then no error is raised if
      the file does not exist.  If RESULT_VARIABLE is given the variable
      will be set to the full filename which has been included or NOTFOUND
      if it failed.
 
      If a module is specified instead of a file, the file with name
      <modulename>.cmake is searched in the CMAKE_MODULE_PATH.
 
      See the cmake_policy() command documentation for discussion of the
      NO_POLICY_SCOPE option.
 
  include_directories
      Add include directories to the build.
 
        include_directories([AFTER|BEFORE] [SYSTEM] dir1 dir2 ...)
 
      Add the given directories to those searched by the compiler for
      include files.  By default the directories are appended onto the
      current list of directories.  This default behavior can be changed by
      setting CMAKE_include_directories_BEFORE to ON.  By using BEFORE or
      AFTER you can select between appending and prepending, independent
      from the default.  If the SYSTEM option is given the compiler will be
      told that the directories are meant as system include directories on
      some platforms.
 
  include_external_msproject
      Include an external Microsoft project file in a workspace.
 
        include_external_msproject(projectname location
                                    dep1 dep2 ...)
 
      Includes an external Microsoft project in the generated workspace
      file.  Currently does nothing on UNIX.  This will create a target
      named INCLUDE_EXTERNAL_MSPROJECT_[projectname].  This can be used in
      the add_dependencies command to make things depend on the external
      project.
 
  include_regular_expression
      Set the regular expression used for dependency checking.
 
        include_regular_expression(regex_match [regex_complain])
 
      Set the regular expressions used in dependency checking.  Only files
      matching regex_match will be traced as dependencies.  Only files
      matching regex_complain will generate warnings if they cannot be found
      (standard header paths are not searched).  The defaults are:
 
        regex_match    = "^.*$" (match everything)
        regex_complain = "^$" (match empty string only)
 
  install
      Specify rules to run at install time.
 
      This command generates installation rules for a project.  Rules
      specified by calls to this command within a source directory are
      executed in order during installation.  The order across directories
      is not defined.
 
      There are multiple signatures for this command.  Some of them define
      installation properties for files and targets.  Properties common to
      multiple signatures are covered here but they are valid only for
      signatures that specify them.
 
      DESTINATION arguments specify the directory on disk to which a file
      will be installed.  If a full path (with a leading slash or drive
      letter) is given it is used directly.  If a relative path is given it
      is interpreted relative to the value of CMAKE_INSTALL_PREFIX.
 
      PERMISSIONS arguments specify permissions for installed files.  Valid
      permissions are OWNER_READ, OWNER_WRITE, OWNER_EXECUTE, GROUP_READ,
      GROUP_WRITE, GROUP_EXECUTE, WORLD_READ, WORLD_WRITE, WORLD_EXECUTE,
      SETUID, and SETGID.  Permissions that do not make sense on certain
      platforms are ignored on those platforms.
 
      The CONFIGURATIONS argument specifies a list of build configurations
      for which the install rule applies (Debug, Release, etc.).
 
      The COMPONENT argument specifies an installation component name with
      which the install rule is associated, such as "runtime" or
      "development".  During component-specific installation only install
      rules associated with the given component name will be executed.
      During a full installation all components are installed.
 
      The RENAME argument specifies a name for an installed file that may be
      different from the original file.  Renaming is allowed only when a
      single file is installed by the command.
 
      The OPTIONAL argument specifies that it is not an error if the file to
      be installed does not exist.
 
      The TARGETS signature:
 
        install(TARGETS targets... [EXPORT <export-name>]
                [[ARCHIVE|LIBRARY|RUNTIME|FRAMEWORK|BUNDLE|
                  PRIVATE_HEADER|PUBLIC_HEADER|RESOURCE]
                  [DESTINATION <dir>]
                  [PERMISSIONS permissions...]
                  [CONFIGURATIONS [Debug|Release|...]]
                  [COMPONENT <component>]
                  [OPTIONAL] [NAMELINK_ONLY|NAMELINK_SKIP]
                ] [...])
 
      The TARGETS form specifies rules for installing targets from a
      project.  There are five kinds of target files that may be installed:
      ARCHIVE, LIBRARY, RUNTIME, FRAMEWORK, and BUNDLE.  Executables are
      treated as RUNTIME targets, except that those marked with the
      MACOSX_BUNDLE property are treated as BUNDLE targets on OS X.  Static
      libraries are always treated as ARCHIVE targets.  Module libraries are
      always treated as LIBRARY targets.  For non-DLL platforms shared
      libraries are treated as LIBRARY targets, except that those marked
      with the FRAMEWORK property are treated as FRAMEWORK targets on OS X.
      For DLL platforms the DLL part of a shared library is treated as a
      RUNTIME target and the corresponding import library is treated as an
      ARCHIVE target.  All Windows-based systems including Cygwin are DLL
      platforms.  The ARCHIVE, LIBRARY, RUNTIME, and FRAMEWORK arguments
      change the type of target to which the subsequent properties apply.
      If none is given the installation properties apply to all target
      types.  If only one is given then only targets of that type will be
      installed (which can be used to install just a DLL or just an import
      library).
 
      The PRIVATE_HEADER, PUBLIC_HEADER, and RESOURCE arguments cause
      subsequent properties to be applied to installing a FRAMEWORK shared
      library target's associated files on non-Apple platforms.  Rules
      defined by these arguments are ignored on Apple platforms because the
      associated files are installed into the appropriate locations inside
      the framework folder.  See documentation of the PRIVATE_HEADER,
      PUBLIC_HEADER, and RESOURCE target properties for details.
 
      Either NAMELINK_ONLY or NAMELINK_SKIP may be specified as a LIBRARY
      option.  On some platforms a versioned shared library has a symbolic
      link such as
 
        lib<name>.so -> lib<name>.so.1
 
      where "lib<name>.so.1" is the soname of the library and "lib<name>.so"
      is a "namelink" allowing linkers to find the library when given
      "-l<name>".  The NAMELINK_ONLY option causes installation of only the
      namelink when a library target is installed.  The NAMELINK_SKIP option
      causes installation of library files other than the namelink when a
      library target is installed.  When neither option is given both
      portions are installed.  On platforms where versioned shared libraries
      do not have namelinks or when a library is not versioned the
      NAMELINK_SKIP option installs the library and the NAMELINK_ONLY option
      installs nothing.  See the VERSION and SOVERSION target properties for
      details on creating versioned shared libraries.
 
      One or more groups of properties may be specified in a single call to
      the TARGETS form of this command.  A target may be installed more than
      once to different locations.  Consider hypothetical targets "myExe",
      "mySharedLib", and "myStaticLib".  The code
 
          install(TARGETS myExe mySharedLib myStaticLib
                  RUNTIME DESTINATION bin
                  LIBRARY DESTINATION lib
                  ARCHIVE DESTINATION lib/static)
          install(TARGETS mySharedLib DESTINATION /some/full/path)
 
      will install myExe to <prefix>/bin and myStaticLib to
      <prefix>/lib/static.  On non-DLL platforms mySharedLib will be
      installed to <prefix>/lib and /some/full/path.  On DLL platforms the
      mySharedLib DLL will be installed to <prefix>/bin and /some/full/path
      and its import library will be installed to <prefix>/lib/static and
      /some/full/path.  On non-DLL platforms mySharedLib will be installed
      to <prefix>/lib and /some/full/path.
 
      The EXPORT option associates the installed target files with an export
      called <export-name>.  It must appear before any RUNTIME, LIBRARY, or
      ARCHIVE options.  See documentation of the install(EXPORT ...)
      signature below for details.
 
      Installing a target with EXCLUDE_FROM_ALL set to true has undefined
      behavior.
 
      The FILES signature:
 
        install(FILES files... DESTINATION <dir>
                [PERMISSIONS permissions...]
                [CONFIGURATIONS [Debug|Release|...]]
                [COMPONENT <component>]
                [RENAME <name>] [OPTIONAL])
 
      The FILES form specifies rules for installing files for a project.
      File names given as relative paths are interpreted with respect to the
      current source directory.  Files installed by this form are by default
      given permissions OWNER_WRITE, OWNER_READ, GROUP_READ, and WORLD_READ
      if no PERMISSIONS argument is given.
 
      The PROGRAMS signature:
 
        install(PROGRAMS files... DESTINATION <dir>
                [PERMISSIONS permissions...]
                [CONFIGURATIONS [Debug|Release|...]]
                [COMPONENT <component>]
                [RENAME <name>] [OPTIONAL])
 
      The PROGRAMS form is identical to the FILES form except that the
      default permissions for the installed file also include OWNER_EXECUTE,
      GROUP_EXECUTE, and WORLD_EXECUTE.  This form is intended to install
      programs that are not targets, such as shell scripts.  Use the TARGETS
      form to install targets built within the project.
 
      The DIRECTORY signature:
 
        install(DIRECTORY dirs... DESTINATION <dir>
                [FILE_PERMISSIONS permissions...]
                [DIRECTORY_PERMISSIONS permissions...]
                [USE_SOURCE_PERMISSIONS]
                [CONFIGURATIONS [Debug|Release|...]]
                [COMPONENT <component>] [FILES_MATCHING]
                [[PATTERN <pattern> | REGEX <regex>]
                  [EXCLUDE] [PERMISSIONS permissions...]] [...])
 
      The DIRECTORY form installs contents of one or more directories to a
      given destination.  The directory structure is copied verbatim to the
      destination.  The last component of each directory name is appended to
      the destination directory but a trailing slash may be used to avoid
      this because it leaves the last component empty.  Directory names
      given as relative paths are interpreted with respect to the current
      source directory.  If no input directory names are given the
      destination directory will be created but nothing will be installed
      into it.  The FILE_PERMISSIONS and DIRECTORY_PERMISSIONS options
      specify permissions given to files and directories in the destination.
      If USE_SOURCE_PERMISSIONS is specified and FILE_PERMISSIONS is not,
      file permissions will be copied from the source directory structure.
      If no permissions are specified files will be given the default
      permissions specified in the FILES form of the command, and the
      directories will be given the default permissions specified in the
      PROGRAMS form of the command.
 
      Installation of directories may be controlled with fine granularity
      using the PATTERN or REGEX options.  These "match" options specify a
      globbing pattern or regular expression to match directories or files
      encountered within input directories.  They may be used to apply
      certain options (see below) to a subset of the files and directories
      encountered.  The full path to each input file or directory (with
      forward slashes) is matched against the expression.  A PATTERN will
      match only complete file names: the portion of the full path matching
      the pattern must occur at the end of the file name and be preceded by
      a slash.  A REGEX will match any portion of the full path but it may
      use '/' and '$' to simulate the PATTERN behavior.  By default all
      files and directories are installed whether or not they are matched.
      The FILES_MATCHING option may be given before the first match option
      to disable installation of files (but not directories) not matched by
      any expression.  For example, the code
 
        install(DIRECTORY src/ DESTINATION include/myproj
                FILES_MATCHING PATTERN "*.h")
 
      will extract and install header files from a source tree.
 
      Some options may follow a PATTERN or REGEX expression and are applied
      only to files or directories matching them.  The EXCLUDE option will
      skip the matched file or directory.  The PERMISSIONS option overrides
      the permissions setting for the matched file or directory.  For
      example the code
 
        install(DIRECTORY icons scripts/ DESTINATION share/myproj
                PATTERN "CVS" EXCLUDE
                PATTERN "scripts/*"
                PERMISSIONS OWNER_EXECUTE OWNER_WRITE OWNER_READ
                            GROUP_EXECUTE GROUP_READ)
 
      will install the icons directory to share/myproj/icons and the scripts
      directory to share/myproj.  The icons will get default file
      permissions, the scripts will be given specific permissions, and any
      CVS directories will be excluded.
 
      The SCRIPT and CODE signature:
 
        install([[SCRIPT <file>] [CODE <code>]] [...])
 
      The SCRIPT form will invoke the given CMake script files during
      installation.  If the script file name is a relative path it will be
      interpreted with respect to the current source directory.  The CODE
      form will invoke the given CMake code during installation.  Code is
      specified as a single argument inside a double-quoted string.  For
      example, the code
 
        install(CODE "MESSAGE(\"Sample install message.\")")
 
      will print a message during installation.
 
      The EXPORT signature:
 
        install(EXPORT <export-name> DESTINATION <dir>
                [NAMESPACE <namespace>] [FILE <name>.cmake]
                [PERMISSIONS permissions...]
                [CONFIGURATIONS [Debug|Release|...]]
                [COMPONENT <component>])
 
      The EXPORT form generates and installs a CMake file containing code to
      import targets from the installation tree into another project.
      Target installations are associated with the export <export-name>
      using the EXPORT option of the install(TARGETS ...) signature
      documented above.  The NAMESPACE option will prepend <namespace> to
      the target names as they are written to the import file.  By default
      the generated file will be called <export-name>.cmake but the FILE
      option may be used to specify a different name.  The value given to
      the FILE option must be a file name with the ".cmake" extension.  If a
      CONFIGURATIONS option is given then the file will only be installed
      when one of the named configurations is installed.  Additionally, the
      generated import file will reference only the matching target
      configurations.  If a COMPONENT option is specified that does not
      match that given to the targets associated with <export-name> the
      behavior is undefined.  If a library target is included in the export
      but a target to which it links is not included the behavior is
      unspecified.
 
      The EXPORT form is useful to help outside projects use targets built
      and installed by the current project.  For example, the code
 
        install(TARGETS myexe EXPORT myproj DESTINATION bin)
        install(EXPORT myproj NAMESPACE mp_ DESTINATION lib/myproj)
 
      will install the executable myexe to <prefix>/bin and code to import
      it in the file "<prefix>/lib/myproj/myproj.cmake".  An outside project
      may load this file with the include command and reference the myexe
      executable from the installation tree using the imported target name
      mp_myexe as if the target were built in its own tree.
 
      NOTE: This command supercedes the INSTALL_TARGETS command and the
      target properties PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT.  It also
      replaces the FILES forms of the INSTALL_FILES and INSTALL_PROGRAMS
      commands.  The processing order of these install rules relative to
      those generated by INSTALL_TARGETS, INSTALL_FILES, and
      INSTALL_PROGRAMS commands is not defined.
 
 
  link_directories
      Specify directories in which the linker will look for libraries.
 
        link_directories(directory1 directory2 ...)
 
      Specify the paths in which the linker should search for libraries.
      The command will apply only to targets created after it is called.
      For historical reasons, relative paths given to this command are
      passed to the linker unchanged (unlike many CMake commands which
      interpret them relative to the current source directory).
 
  list
      List operations.
 
        list(LENGTH <list> <output variable>)
        list(GET <list> <element index> [<element index> ...] <output variable>)
        list(APPEND <list> <element> [<element> ...])
        list(FIND <list> <value> <output variable>)
        list(INSERT <list> <element_index> <element> [<element> ...])
        list(REMOVE_ITEM <list> <value> [<value> ...])
        list(REMOVE_AT <list> <index> [<index> ...])
        list(REMOVE_DUPLICATES <list>)
        list(REVERSE <list>)
        list(SORT <list>)
 
      LENGTH will return a given list's length.
 
      GET will return list of elements specified by indices from the list.
 
      APPEND will append elements to the list.
 
      FIND will return the index of the element specified in the list or -1
      if it wasn't found.
 
      INSERT will insert elements to the list to the specified location.
 
      REMOVE_AT and REMOVE_ITEM will remove items from the list.  The
      difference is that REMOVE_ITEM will remove the given items, while
      REMOVE_AT will remove the items at the given indices.
 
      REMOVE_DUPLICATES will remove duplicated items in the list.
 
      REVERSE reverses the contents of the list in-place.
 
      SORT sorts the list in-place alphabetically.
 
      NOTES: A list in cmake is a ; separated group of strings.  To create a
      list the set command can be used.  For example, set(var a b c d e)
      creates a list with a;b;c;d;e, and set(var "a b c d e") creates a
      string or a list with one item in it.
 
      When specifying index values, if <element index> is 0 or greater, it
      is indexed from the beginning of the list, with 0 representing the
      first list element.  If <element index> is -1 or lesser, it is indexed
      from the end of the list, with -1 representing the last list element.
      Be careful when counting with negative indices: they do not start from
      0.  -0 is equivalent to 0, the first list element.
 
 
  load_cache
      Load in the values from another project's CMake cache.
 
        load_cache(pathToCacheFile READ_WITH_PREFIX
                    prefix entry1...)
 
      Read the cache and store the requested entries in variables with their
      name prefixed with the given prefix.  This only reads the values, and
      does not create entries in the local project's cache.
 
        load_cache(pathToCacheFile [EXCLUDE entry1...]
                    [INCLUDE_INTERNALS entry1...])
 
      Load in the values from another cache and store them in the local
      project's cache as internal entries.  This is useful for a project
      that depends on another project built in a different tree.  EXCLUDE
      option can be used to provide a list of entries to be excluded.
      INCLUDE_INTERNALS can be used to provide a list of internal entries to
      be included.  Normally, no internal entries are brought in.  Use of
      this form of the command is strongly discouraged, but it is provided
      for backward compatibility.
 
  load_command
      Load a command into a running CMake.
 
        load_command(COMMAND_NAME <loc1> [loc2 ...])
 
      The given locations are searched for a library whose name is
      cmCOMMAND_NAME.  If found, it is loaded as a module and the command is
      added to the set of available CMake commands.  Usually, TRY_COMPILE is
      used before this command to compile the module.  If the command is
      successfully loaded a variable named
 
        CMAKE_LOADED_COMMAND_<COMMAND_NAME>
 
      will be set to the full path of the module that was loaded.  Otherwise
      the variable will not be set.
 
  macro
      Start recording a macro for later invocation as a command.
 
        macro(<name> [arg1 [arg2 [arg3 ...]]])
          COMMAND1(ARGS ...)
          COMMAND2(ARGS ...)
          ...
        endmacro(<name>)
 
      Define a macro named <name> that takes arguments named arg1 arg2 arg3
      (...).  Commands listed after macro, but before the matching endmacro,
      are not invoked until the macro is invoked.  When it is invoked, the
      commands recorded in the macro are first modified by replacing formal
      parameters (${arg1}) with the arguments passed, and then invoked as
      normal commands.  In addition to referencing the formal parameters you
      can reference the values ${ARGC} which will be set to the number of
      arguments passed into the function as well as ${ARGV0} ${ARGV1}
      ${ARGV2} ...  which will have the actual values of the arguments
      passed in.  This facilitates creating macros with optional arguments.
      Additionally ${ARGV} holds the list of all arguments given to the
      macro and ${ARGN} holds the list of argument pass the last expected
      argument.  Note that the parameters to a macro and values such as ARGN
      are not variables in the usual CMake sense.  They are string
      replacements much like the c preprocessor would do with a macro.  If
      you want true CMake variables you should look at the function command.
 
      See the cmake_policy() command documentation for the behavior of
      policies inside macros.
 
  mark_as_advanced
      Mark cmake cached variables as advanced.
 
        mark_as_advanced([CLEAR|FORCE] VAR VAR2 VAR...)
 
      Mark the named cached variables as advanced.  An advanced variable
      will not be displayed in any of the cmake GUIs unless the show
      advanced option is on.  If CLEAR is the first argument advanced
      variables are changed back to unadvanced.  If FORCE is the first
      argument, then the variable is made advanced.  If neither FORCE nor
      CLEAR is specified, new values will be marked as advanced, but if the
      variable already has an advanced/non-advanced state, it will not be
      changed.
 
      It does nothing in script mode.
 
  math
      Mathematical expressions.
 
        math(EXPR <output variable> <math expression>)
 
      EXPR evaluates mathematical expression and return result in the output
      variable.  Example mathematical expression is '5 * ( 10 + 13 )'.
      Supported operators are + - * / % | & ^ ~ << >> * / %.  They have the
      same meaning as they do in c code.
 
  message
      Display a message to the user.
 
        message([SEND_ERROR | STATUS | FATAL_ERROR]
                "message to display" ...)
 
      By default the message is displayed in a pop up window (CMakeSetup),
      or in the stdout of cmake, or the error section of ccmake.  If the
      first argument is SEND_ERROR then an error is raised, and the generate
      phase will be skipped.  If the first argument is FATAL_ERROR, all
      processing is halted.  If the first argument is STATUS then the
      message is displayed in the progress line for the GUI, or with a -- in
      the command line cmake.
 
  option
      Provides an option that the user can optionally select.
 
        option(<option_variable> "help string describing option"
                [initial value])
 
      Provide an option for the user to select as ON or OFF.  If no initial
      value is provided, OFF is used.
 
  output_required_files
      Output a list of required source files for a specified source file.
 
        output_required_files(srcfile outputfile)
 
      Outputs a list of all the source files that are required by the
      specified srcfile.  This list is written into outputfile.  This is
      similar to writing out the dependencies for srcfile except that it
      jumps from .h files into .cxx, .c and .cpp files if possible.
 
  project
      Set a name for the entire project.
 
        project(projectname [CXX] [C] [Java])
 
      Sets the name of the project.  This creates the variables
      projectname_BINARY_DIR and projectname_SOURCE_DIR.  Optionally you can
      specify which languages your project supports.  By default all
      languages are supported.  If you do not have a C++ compiler, but want
      to build a c program with cmake, then use this option.
 
  qt_wrap_cpp
      Create Qt Wrappers.
 
        qt_wrap_cpp(resultingLibraryName DestName
                    SourceLists ...)
 
      Produce moc files for all the .h files listed in the SourceLists.  The
      moc files will be added to the library using the DestName source list.
 
  qt_wrap_ui
      Create Qt user interfaces Wrappers.
 
        qt_wrap_ui(resultingLibraryName HeadersDestName
                    SourcesDestName SourceLists ...)
 
      Produce .h and .cxx files for all the .ui files listed in the
      SourceLists.  The .h files will be added to the library using the
      HeadersDestNamesource list.  The .cxx files will be added to the
      library using the SourcesDestNamesource list.
 
  remove_definitions
      Removes -D define flags added by add_definitions.
 
        remove_definitions(-DFOO -DBAR ...)
 
      Removes flags (added by add_definitions) from the compiler command
      line for sources in the current directory and below.
 
  return
      Return from a file, directory or function.
 
        return()
 
      Returns from a file, directory or function.  When this command is
      encountered in an included file (via include() or find_package()), it
      causes processing of the current file to stop and control is returned
      to the including file.  If it is encountered in a file which is not
      included by another file, e.g.  a CMakeLists.txt, control is returned
      to the parent directory if there is one.  If return is called in a
      function, control is returned to the caller of the function.  Note
      that a macro is not a function and does not handle return like a
      function does.
 
  separate_arguments
      Split space separated arguments into a semi-colon separated list.
 
        separate_arguments(VARIABLE)
 
      Convert the value of VARIABLE to a semi-colon separated list.  All
      spaces are replaced with ';'.  This helps with generating command
      lines.
 
  set
      Set a CMAKE variable to a given value.
 
        set(<variable> <value> [[CACHE <type> <docstring> [FORCE]] | PARENT_SCOPE])
 
      Within CMake sets <variable> to the value <value>.  <value> is
      expanded before <variable> is set to it.  If CACHE is present, then
      the <variable> is put in the cache.  <type> and <docstring> are then
      required.  <type> is used by the CMake GUI to choose a widget with
      which the user sets a value.  The value for <type> may be one of
 
        FILEPATH = File chooser dialog.
        PATH    = Directory chooser dialog.
        STRING  = Arbitrary string.
        BOOL    = Boolean ON/OFF checkbox.
        INTERNAL = No GUI entry (used for persistent variables).
 
      If <type> is INTERNAL, then the <value> is always written into the
      cache, replacing any values existing in the cache.  If it is not a
      cache variable, then this always writes into the current makefile.
      The FORCE option will overwrite the cache value removing any changes
      by the user.
 
      If PARENT_SCOPE is present, the variable will be set in the scope
      above the current scope.  Each new directory or function creates a new
      scope.  This command will set the value of a variable into the parent
      directory or calling function (whichever is applicable to the case at
      hand) If VALUE is not specified then the variable is removed from the
      parent scope.
 
        set(<variable> <value1> ... <valueN>)
 
      In this case <variable> is set to a semicolon separated list of
      values.
 
      <variable> can be an environment variable such as:
 
        set( ENV{PATH} /home/martink )
 
      in which case the environment variable will be set.
 
  set_directory_properties
      Set a property of the directory.
 
        set_directory_properties(PROPERTIES prop1 value1 prop2 value2)
 
      Set a property for the current directory and subdirectories.  If the
      property is not found, CMake will report an error.  The properties
      include: INCLUDE_DIRECTORIES, LINK_DIRECTORIES,
      INCLUDE_REGULAR_EXPRESSION, and ADDITIONAL_MAKE_CLEAN_FILES.
 
      ADDITIONAL_MAKE_CLEAN_FILES is a list of files that will be cleaned as
      a part of "make clean" stage.
 
  set_property
      Set a named property in a given scope.
 
        set_property(<GLOBAL                            |
                      DIRECTORY [dir]                  |
                      TARGET    [target1 [target2 ...]] |
                      SOURCE    [src1 [src2 ...]]      |
                      TEST      [test1 [test2 ...]]>
                      [APPEND]
                      PROPERTY <name> [value1 [value2 ...]])
 
      Set one property on zero or more objects of a scope.  The first
      argument determines the scope in which the property is set.  It must
      be one of the following:
 
      GLOBAL scope is unique and does not accept a name.
 
      DIRECTORY scope defaults to the current directory but another
      directory (already processed by CMake) may be named by full or
      relative path.
 
      TARGET scope may name zero or more existing targets.
 
      SOURCE scope may name zero or more source files.
 
      TEST scope may name zero or more existing tests.
 
      The required PROPERTY option is immediately followed by the name of
      the property to set.  Remaining arguments are used to compose the
      property value in the form of a semicolon-separated list.  If the
      APPEND option is given the list is appended to any existing property
      value.
 
  set_source_files_properties
      Source files can have properties that affect how they are built.
 
        set_source_files_properties(file1 file2 ...
                                    PROPERTIES prop1 value1
                                    prop2 value2 ...)
 
      Set properties on a file.  The syntax for the command is to list all
      the files you want to change, and then provide the values you want to
      set next.  You can make up your own properties as well.  The following
      are used by CMake.  The ABSTRACT flag (boolean) is used by some class
      wrapping commands.  If WRAP_EXCLUDE (boolean) is true then many
      wrapping commands will ignore this file.  If GENERATED (boolean) is
      true then it is not an error if this source file does not exist when
      it is added to a target.  Obviously, it must be created (presumably by
      a custom command) before the target is built.  If the HEADER_FILE_ONLY
      (boolean) property is true then the file is not compiled.  This is
      useful if you want to add extra non build files to an IDE.
      OBJECT_DEPENDS (string) adds dependencies to the object file.
      COMPILE_FLAGS (string) is passed to the compiler as additional command
      line arguments when the source file is compiled.  LANGUAGE (string)
      CXX|C will change the default compiler used to compile the source
      file.  The languages used need to be enabled in the PROJECT command.
      If SYMBOLIC (boolean) is set to true the build system will be informed
      that the source file is not actually created on disk but instead used
      as a symbolic name for a build rule.
 
  set_target_properties
      Targets can have properties that affect how they are built.
 
        set_target_properties(target1 target2 ...
                              PROPERTIES prop1 value1
                              prop2 value2 ...)
 
      Set properties on a target.  The syntax for the command is to list all
      the files you want to change, and then provide the values you want to
      set next.  You can use any prop value pair you want and extract it
      later with the GET_TARGET_PROPERTY command.
 
      Properties that affect the name of a target's output file are as
      follows.  The PREFIX and SUFFIX properties override the default target
      name prefix (such as "lib") and suffix (such as ".so").  IMPORT_PREFIX
      and IMPORT_SUFFIX are the equivalent properties for the import library
      corresponding to a DLL (for SHARED library targets).  OUTPUT_NAME sets
      the real name of a target when it is built and can be used to help
      create two targets of the same name even though CMake requires unique
      logical target names.  There is also a <CONFIG>_OUTPUT_NAME that can
      set the output name on a per-configuration basis.  <CONFIG>_POSTFIX
      sets a postfix for the real name of the target when it is built under
      the configuration named by <CONFIG> (in upper-case, such as
      "DEBUG_POSTFIX").  The value of this property is initialized when the
      target is created to the value of the variable CMAKE_<CONFIG>_POSTFIX
      (except for executable targets because earlier CMake versions which
      did not use this variable for executables).
 
      The LINK_FLAGS property can be used to add extra flags to the link
      step of a target.  LINK_FLAGS_<CONFIG> will add to the configuration
      <CONFIG>, for example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO.
      DEFINE_SYMBOL sets the name of the preprocessor symbol defined when
      compiling sources in a shared library.  If not set here then it is set
      to target_EXPORTS by default (with some substitutions if the target is
      not a valid C identifier).  This is useful for headers to know whether
      they are being included from inside their library our outside to
      properly setup dllexport/dllimport decorations.  The COMPILE_FLAGS
      property sets additional compiler flags used to build sources within
      the target.  It may also be used to pass additional preprocessor
      definitions.
 
      The LINKER_LANGUAGE property is used to change the tool used to link
      an executable or shared library.  The default is set the language to
      match the files in the library.  CXX and C are common values for this
      property.
 
      For shared libraries VERSION and SOVERSION can be used to specify the
      build version and api version respectively.  When building or
      installing appropriate symlinks are created if the platform supports
      symlinks and the linker supports so-names.  If only one of both is
      specified the missing is assumed to have the same version number.  For
      executables VERSION can be used to specify the build version.  When
      building or installing appropriate symlinks are created if the
      platform supports symlinks.  For shared libraries and executables on
      Windows the VERSION attribute is parsed to extract a "major.minor"
      version number.  These numbers are used as the image version of the
      binary.
 
      There are a few properties used to specify RPATH rules.  INSTALL_RPATH
      is a semicolon-separated list specifying the rpath to use in installed
      targets (for platforms that support it).  INSTALL_RPATH_USE_LINK_PATH
      is a boolean that if set to true will append directories in the linker
      search path and outside the project to the INSTALL_RPATH.
      SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic
      generation of an rpath allowing the target to run from the build tree.
      BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link the
      target in the build tree with the INSTALL_RPATH.  This takes
      precedence over SKIP_BUILD_RPATH and avoids the need for relinking
      before installation.  INSTALL_NAME_DIR is a string specifying the
      directory portion of the "install_name" field of shared libraries on
      Mac OSX to use in the installed targets.  When the target is created
      the values of the variables CMAKE_INSTALL_RPATH,
      CMAKE_INSTALL_RPATH_USE_LINK_PATH, CMAKE_SKIP_BUILD_RPATH,
      CMAKE_BUILD_WITH_INSTALL_RPATH, and CMAKE_INSTALL_NAME_DIR are used to
      initialize these properties.
 
      PROJECT_LABEL can be used to change the name of the target in an IDE
      like visual studio.  VS_KEYWORD can be set to change the visual studio
      keyword, for example QT integration works better if this is set to
      Qt4VSv1.0.
 
      VS_SCC_PROJECTNAME, VS_SCC_LOCALPATH, VS_SCC_PROVIDER can be set to
      add support for source control bindings in a Visual Studio project
      file.
 
      When a library is built CMake by default generates code to remove any
      existing library using all possible names.  This is needed to support
      libraries that switch between STATIC and SHARED by a user option.
      However when using OUTPUT_NAME to build a static and shared library of
      the same name using different logical target names the two targets
      will remove each other's files.  This can be prevented by setting the
      CLEAN_DIRECT_OUTPUT property to 1.
 
      The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old
      way to specify CMake scripts to run before and after installing a
      target.  They are used only when the old INSTALL_TARGETS command is
      used to install the target.  Use the INSTALL command instead.
 
      The EXCLUDE_FROM_DEFAULT_BUILD property is used by the visual studio
      generators.  If it is set to 1 the target will not be part of the
      default build when you select "Build Solution".
 
  set_tests_properties
      Set a property of the tests.
 
        set_tests_properties(test1 [test2...] PROPERTIES prop1 value1 prop2 value2)
 
      Set a property for the tests.  If the property is not found, CMake
      will report an error.  The properties include:
 
      WILL_FAIL: If set to true, this will invert the pass/fail flag of the
      test.
 
      PASS_REGULAR_EXPRESSION: If set, the test output will be checked
      against the specified regular expressions and at least one of the
      regular expressions has to match, otherwise the test will fail.
 
        Example: PASS_REGULAR_EXPRESSION "TestPassed;All ok"
 
      FAIL_REGULAR_EXPRESSION: If set, if the output will match to one of
      specified regular expressions, the test will fail.
 
        Example: PASS_REGULAR_EXPRESSION "[^a-z]Error;ERROR;Failed"
 
      Both PASS_REGULAR_EXPRESSION and FAIL_REGULAR_EXPRESSION expect a list
      of regular expressions.
 
 
  site_name
      Set the given variable to the name of the computer.
 
        site_name(variable)
 
 
  source_group
      Define a grouping for sources in the makefile.
 
        source_group(name [REGULAR_EXPRESSION regex] [FILES src1 src2 ...])
 
      Defines a group into which sources will be placed in project files.
      This is mainly used to setup file tabs in Visual Studio.  Any file
      whose name is listed or matches the regular expression will be placed
      in this group.  If a file matches multiple groups, the LAST group that
      explicitly lists the file will be favored, if any.  If no group
      explicitly lists the file, the LAST group whose regular expression
      matches the file will be favored.
 
      The name of the group may contain backslashes to specify subgroups:
 
        source_group(outer\\inner ...)
 
      For backwards compatibility, this command is also supports the format:
 
        source_group(name regex)
 
  string
      String operations.
 
        string(REGEX MATCH <regular_expression>
                <output variable> <input> [<input>...])
        string(REGEX MATCHALL <regular_expression>
                <output variable> <input> [<input>...])
        string(REGEX REPLACE <regular_expression>
                <replace_expression> <output variable>
                <input> [<input>...])
        string(REPLACE <match_string>
                <replace_string> <output variable>
                <input> [<input>...])
        string(COMPARE EQUAL <string1> <string2> <output variable>)
        string(COMPARE NOTEQUAL <string1> <string2> <output variable>)
        string(COMPARE LESS <string1> <string2> <output variable>)
        string(COMPARE GREATER <string1> <string2> <output variable>)
        string(ASCII <number> [<number> ...] <output variable>)
        string(CONFIGURE <string1> <output variable>
                [@ONLY] [ESCAPE_QUOTES])
        string(TOUPPER <string1> <output variable>)
        string(TOLOWER <string1> <output variable>)
        string(LENGTH <string> <output variable>)
        string(SUBSTRING <string> <begin> <length> <output variable>)
        string(STRIP <string> <output variable>)
        string(RANDOM [LENGTH <length>] [ALPHABET <alphabet>]
                <output variable>)
 
      REGEX MATCH will match the regular expression once and store the match
      in the output variable.
 
      REGEX MATCHALL will match the regular expression as many times as
      possible and store the matches in the output variable as a list.
 
      REGEX REPLACE will match the regular expression as many times as
      possible and substitute the replacement expression for the match in
      the output.  The replace expression may refer to paren-delimited
      subexpressions of the match using \1, \2, ..., \9.  Note that two
      backslashes (\\1) are required in CMake code to get a backslash
      through argument parsing.
 
      REPLACE will replace all occurrences of match_string in the input with
      replace_string and store the result in the output.
 
      COMPARE EQUAL/NOTEQUAL/LESS/GREATER will compare the strings and store
      true or false in the output variable.
 
      ASCII will convert all numbers into corresponding ASCII characters.
 
      CONFIGURE will transform a string like CONFIGURE_FILE transforms a
      file.
 
      TOUPPER/TOLOWER will convert string to upper/lower characters.
 
      LENGTH will return a given string's length.
 
      SUBSTRING will return a substring of a given string.
 
      STRIP will return a substring of a given string with leading and
      trailing spaces removed.
 
      RANDOM will return a random string of given length consisting of
      characters from the given alphabet.  Default length is 5 characters
      and default alphabet is all numbers and upper and lower case letters.
 
      The following characters have special meaning in regular expressions:
 
          ^        Matches at beginning of a line
          $        Matches at end of a line
          .        Matches any single character
          [ ]      Matches any character(s) inside the brackets
          [^ ]      Matches any character(s) not inside the brackets
          -        Matches any character in range on either side of a dash
          *        Matches preceding pattern zero or more times
          +        Matches preceding pattern one or more times
          ?        Matches preceding pattern zero or once only
          |        Matches a pattern on either side of the |
          ()        Saves a matched subexpression, which can be referenced in the REGEX REPLACE operation. Additionally it is saved in the special CMake variables CMAKE_MATCH_(0..9).
 
  target_link_libraries
      Link a target to given libraries.
 
        target_link_libraries(<target> [lib1 [lib2 [...]]]
                              [[debug|optimized|general] <lib>] ...)
 
      Specify a list of libraries to be linked into the specified target.
      If any library name matches that of a target in the current project a
      dependency will automatically be added in the build system to make
      sure the library being linked is up-to-date before the target links.
 
      A "debug", "optimized", or "general" keyword indicates that the
      library immediately following it is to be used only for the
      corresponding build configuration.  The "debug" keyword corresponds to
      the Debug configuration (or to configurations named in the
      DEBUG_CONFIGURATIONS global property if it is set).  The "optimized"
      keyword corresponds to all other configurations.  The "general"
      keyword corresponds to all configurations, and is purely optional
      (assumed if omitted).  Higher granularity may be achieved for
      per-configuration rules by creating and linking to IMPORTED library
      targets.  See the IMPORTED mode of the add_library command for more
      information.
 
      Library dependencies are transitive by default.  When this target is
      linked into another target then the libraries linked to this target
      will appear on the link line for the other target too.  See the
      LINK_INTERFACE_LIBRARIES target property to override the set of
      transitive link dependencies for a target.
 
        target_link_libraries(<target> LINK_INTERFACE_LIBRARIES
                              [[debug|optimized|general] <lib>] ...)
 
      The LINK_INTERFACE_LIBRARIES mode appends the libraries to the
      LINK_INTERFACE_LIBRARIES and its per-configuration equivalent target
      properties instead of using them for linking.  Libraries specified as
      "debug" are appended to the the LINK_INTERFACE_LIBRARIES_DEBUG
      property (or to the properties corresponding to configurations listed
      in the DEBUG_CONFIGURATIONS global property if it is set).  Libraries
      specified as "optimized" are appended to the the
      LINK_INTERFACE_LIBRARIES property.  Libraries specified as "general"
      (or without any keyword) are treated as if specified for both "debug"
      and "optimized".
 
  try_compile
      Try compiling some code.
 
        try_compile(RESULT_VAR bindir srcdir
                    projectName <targetname> [CMAKE_FLAGS <Flags>]
                    [OUTPUT_VARIABLE var])
 
      Try compiling a program.  In this form, srcdir should contain a
      complete CMake project with a CMakeLists.txt file and all sources.
      The bindir and srcdir will not be deleted after this command is run.
      If <target name> is specified then build just that target otherwise
      the all or ALL_BUILD target is built.
 
        try_compile(RESULT_VAR bindir srcfile
                    [CMAKE_FLAGS <Flags>]
                    [COMPILE_DEFINITIONS <flags> ...]
                    [OUTPUT_VARIABLE var]
                    [COPY_FILE <filename> )
 
      Try compiling a srcfile.  In this case, the user need only supply a
      source file.  CMake will create the appropriate CMakeLists.txt file to
      build the source.  If COPY_FILE is used, the compiled file will be
      copied to the given file.
 
      In this version all files in bindir/CMakeFiles/CMakeTmp, will be
      cleaned automatically, for debugging a --debug-trycompile can be
      passed to cmake to avoid the clean.  Some extra flags that can be
      included are, INCLUDE_DIRECTORIES, LINK_DIRECTORIES, and
      LINK_LIBRARIES.  COMPILE_DEFINITIONS are -Ddefinition that will be
      passed to the compile line.  try_compile creates a CMakeList.txt file
      on the fly that looks like this:
 
        add_definitions( <expanded COMPILE_DEFINITIONS from calling cmake>)
        include_directories(${INCLUDE_DIRECTORIES})
        link_directories(${LINK_DIRECTORIES})
        add_executable(cmTryCompileExec sources)
        target_link_libraries(cmTryCompileExec ${LINK_LIBRARIES})
 
      In both versions of the command, if OUTPUT_VARIABLE is specified, then
      the output from the build process is stored in the given variable.
      Return the success or failure in RESULT_VAR.  CMAKE_FLAGS can be used
      to pass -DVAR:TYPE=VALUE flags to the cmake that is run during the
      build.
 
  try_run
      Try compiling and then running some code.
 
        try_run(RUN_RESULT_VAR COMPILE_RESULT_VAR
                bindir srcfile [CMAKE_FLAGS <Flags>]
                [COMPILE_DEFINITIONS <flags>]
                [COMPILE_OUTPUT_VARIABLE comp]
                [RUN_OUTPUT_VARIABLE run]
                [OUTPUT_VARIABLE var]
                [ARGS <arg1> <arg2>...])
 
      Try compiling a srcfile.  Return TRUE or FALSE for success or failure
      in COMPILE_RESULT_VAR.  Then if the compile succeeded, run the
      executable and return its exit code in RUN_RESULT_VAR.  If the
      executable was built, but failed to run, then RUN_RESULT_VAR will be
      set to FAILED_TO_RUN.  COMPILE_OUTPUT_VARIABLE specifies the variable
      where the output from the compile step goes.  RUN_OUTPUT_VARIABLE
      specifies the variable where the output from the running executable
      goes.
 
      For compatibility reasons OUTPUT_VARIABLE is still supported, which
      gives you the output from the compile and run step combined.
 
     
 
      Cross compiling issues
 
      When cross compiling, the executable compiled in the first step
      usually cannot be run on the build host.  try_run() checks the
      CMAKE_CROSSCOMPILING variable to detect whether CMake is in
      crosscompiling mode.  If that's the case, it will still try to compile
      the executable, but it will not try to run the executable.  Instead it
      will create cache variables which must be filled by the user or by
      presetting them in some CMake script file to the values the executable
      would have produced if it would have been run on its actual target
      platform.  These variables are RUN_RESULT_VAR (explanation see above)
      and if RUN_OUTPUT_VARIABLE (or OUTPUT_VARIABLE) was used, an
      additional cache variable
      RUN_RESULT_VAR__COMPILE_RESULT_VAR__TRYRUN_OUTPUT.This is intended to
      hold stdout and stderr from the executable.
 
      In order to make cross compiling your project easier, use try_run only
      if really required.  If you use try_run, use RUN_OUTPUT_VARIABLE (or
      OUTPUT_VARIABLE) only if really required.  Using them will require
      that when crosscompiling, the cache variables will have to be set
      manually to the output of the executable.  You can also "guard" the
      calls to try_run with if(CMAKE_CROSSCOMPILING) and provide an
      easy-to-preset alternative for this case.
 
 
  unset
      Unset a variable, cache variable, or environment variable.
 
        unset(<variable> [CACHE])
 
      Removes the specified variable causing it to become undefined.  If
      CACHE is present then the variable is removed from the cache instead
      of the current scope.
 
      <variable> can be an environment variable such as:
 
        unset(ENV{LD_LIBRARY_PATH})
 
      in which case the variable will be removed from the current
      environment.
 
  variable_watch
      Watch the CMake variable for change.
 
        variable_watch(<variable name> [<command to execute>])
 
      If the specified variable changes, the message will be printed about
      the variable being changed.  If the command is specified, the command
      will be executed.  The command will receive the following arguments:
      COMMAND(<variable> <access> <value> <current list file> <stack>)
 
  while
      Evaluate a group of commands while a condition is true
 
        while(condition)
          COMMAND1(ARGS ...)
          COMMAND2(ARGS ...)
          ...
        endwhile(condition)
 
      All commands between while and the matching endwhile are recorded
      without being invoked.  Once the endwhile is evaluated, the recorded
      list of commands is invoked as long as the condition is true.  The
      condition is evaluated using the same logic as the if command.
 
------------------------------------------------------------------------------
Properties
 
  CMake Properties - Properties supported by CMake, the Cross-Platform Makefile Generator.
 
This is the documentation for the properties supported by CMake.  Properties
can have different scopes.  They can either be assigned to a source file, a
directory, a target or globally to CMake.  By modifying the values of
properties the behaviour of the build system can be customized.
 
------------------------------------------------------------------------------
Properties of Global Scope
 
  ALLOW_DUPLICATE_CUSTOM_TARGETS
      Allow duplicate custom targets to be created.
 
      Normally CMake requires that all targets built in a project have
      globally unique logical names (see policy CMP0002).  This is necessary
      to generate meaningful project file names in Xcode and VS IDE
      generators.  It also allows the target names to be referenced
      unambiguously.
 
      Makefile generators are capable of supporting duplicate custom target
      names.  For projects that care only about Makefile generators and do
      not wish to support Xcode or VS IDE generators, one may set this
      property to true to allow duplicate custom targets.  The property
      allows multiple add_custom_target command calls in different
      directories to specify the same target name.  However, setting this
      property will cause non-Makefile generators to produce an error and
      refuse to generate the project.
 
  DEBUG_CONFIGURATIONS
      Specify which configurations are for debugging.
 
      The value must be a semi-colon separated list of configuration names.
      Currently this property is used only by the target_link_libraries
      command (see its documentation for details).  Additional uses may be
      defined in the future.
 
      This property must be set at the top level of the project and before
      the first target_link_libraries command invocation.  If any entry in
      the list does not match a valid configuration for the project the
      behavior is undefined.
 
  DISABLED_FEATURES
      List of features which are disabled during the CMake run.
 
      List of features which are disabled during the CMake run.  Be default
      it contains the names of all packages which were not found.  This is
      determined using the <NAME>_FOUND variables.  Packages which are
      searched QUIET are not listed.  A project can add its own features to
      this list.This property is used by the macros in FeatureSummary.cmake.
 
  ENABLED_FEATURES
      List of features which are enabled during the CMake run.
 
      List of features which are enabled during the CMake run.  Be default
      it contains the names of all packages which were found.  This is
      determined using the <NAME>_FOUND variables.  Packages which are
      searched QUIET are not listed.  A project can add its own features to
      this list.This property is used by the macros in FeatureSummary.cmake.
 
  ENABLED_LANGUAGES
      Read-only property that contains the list of currently enabled
      languages
 
      Set to list of currently enabled lanauges.
 
  FIND_LIBRARY_USE_LIB64_PATHS
      Whether FIND_LIBRARY should automatically search lib64 directories.
 
      FIND_LIBRARY_USE_LIB64_PATHS is a boolean specifying whether the
      FIND_LIBRARY command should automatically search the lib64 variant of
      directories called lib in the search path when building 64-bit
      binaries.
 
  GLOBAL_DEPENDS_DEBUG_MODE
      Enable global target dependency graph debug mode.
 
      CMake automatically analyzes the global inter-target dependency graph
      at the beginning of native build system generation.  This property
      causes it to display details of its analysis to stderr.
 
  IN_TRY_COMPILE
      Read-only property that is true during a try-compile configuration.
 
      True when building a project inside a TRY_COMPILE or TRY_RUN command.
 
  PACKAGES_FOUND
      List of packages which were found during the CMake run.
 
      List of packages which were found during the CMake run.  Whether a
      package has been found is determined using the <NAME>_FOUND variables.
 
  PACKAGES_NOT_FOUND
      List of packages which were not found during the CMake run.
 
      List of packages which were not found during the CMake run.  Whether a
      package has been found is determined using the <NAME>_FOUND variables.
 
  REPORT_UNDEFINED_PROPERTIES
      If set, report any undefined properties to this file.
 
      If this property is set to a filename then when CMake runs it will
      report any properties or variables that were accessed but not defined
      into the filename specified in this property.
 
  TARGET_ARCHIVES_MAY_BE_SHARED_LIBS
      Set if shared libraries may be named like archives.
 
      On AIX shared libraries may be named "lib<name>.a".  This property is
      set to true on such platforms.
 
  TARGET_SUPPORTS_SHARED_LIBS
      Does the target platform support shared libraries.
 
      TARGET_SUPPORTS_SHARED_LIBS is a boolean specifying whether the target
      platform supports shared libraries.  Basically all current general
      general purpose OS do so, the exception are usually embedded systems
      with no or special OSs.
 
  __CMAKE_DELETE_CACHE_CHANGE_VARS_
      Internal property
 
      Used to detect compiler changes, Do not set.
 
------------------------------------------------------------------------------
Properties on Directories
 
  ADDITIONAL_MAKE_CLEAN_FILES
      Additional files to clean during the make clean stage.
 
      A list of files that will be cleaned as a part of the "make clean"
      stage.
 
  CACHE_VARIABLES
      List of cache variables available in the current directory.
 
      This read-only property specifies the list of CMake cache variables
      currently defined.  It is intended for debugging purposes.
 
  CLEAN_NO_CUSTOM
      Should the output of custom commands be left.
 
      If this is true then the outputs of custom commands for this directory
      will not be removed during the "make clean" stage.
 
  COMPILE_DEFINITIONS
      Preprocessor definitions for compiling a directory's sources.
 
      The COMPILE_DEFINITIONS property may be set to a list of preprocessor
      definitions using the syntax VAR or VAR=value.  Function-style
      definitions are not supported.  CMake will automatically escape the
      value correctly for the native build system (note that CMake language
      syntax may require escapes to specify some values).  This property may
      be set on a per-configuration basis using the name
      COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an upper-case name (ex.
      "COMPILE_DEFINITIONS_DEBUG").  This property will be initialized in
      each directory by its value in the directory's parent.
 
      CMake will automatically drop some definitions that are not supported
      by the native build tool.  The VS6 IDE does not support definitions
      with values (but NMake does).
 
      Dislaimer: Most native build tools have poor support for escaping
      certain values.  CMake has work-arounds for many cases but some values
      may just not be possible to pass correctly.  If a value does not seem
      to be escaped correctly, do not attempt to work-around the problem by
      adding escape sequences to the value.  Your work-around may break in a
      future version of CMake that has improved escape support.  Instead
      consider defining the macro in a (configured) header file.  Then
      report the limitation.
 
  COMPILE_DEFINITIONS_<CONFIG>
      Per-configuration preprocessor definitions in a directory.
 
      This is the configuration-specific version of COMPILE_DEFINITIONS.
      This property will be initialized in each directory by its value in
      the directory's parent.
 
 
  DEFINITIONS
      For CMake 2.4 compatibility only.  Use COMPILE_DEFINITIONS instead.
 
      This read-only property specifies the list of flags given so far to
      the add_definitions command.  It is intended for debugging purposes.
      Use the COMPILE_DEFINITIONS instead.
 
  EXCLUDE_FROM_ALL
      Exclude the directory from the all target of its parent.
 
      A property on a directory that indicates if its targets are excluded
      from the default build target.  If it is not, then with a Makefile for
      example typing make will cause the targets to be built.  The same
      concept applies to the default build of other generators.
 
  IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
      Specify #include line transforms for dependencies in a directory.
 
      This property specifies rules to transform macro-like #include lines
      during implicit dependency scanning of C and C++ source files.  The
      list of rules must be semicolon-separated with each entry of the form
      "A_MACRO(%)=value-with-%" (the % must be literal).  During dependency
      scanning occurrences of A_MACRO(...) on #include lines will be
      replaced by the value given with the macro argument substituted for
      '%'.  For example, the entry
 
        MYDIR(%)=<mydir/%>
 
      will convert lines of the form
 
        #include MYDIR(myheader.h)
 
      to
 
        #include <mydir/myheader.h>
 
      allowing the dependency to be followed.
 
      This property applies to sources in all targets within a directory.
      The property value is initialized in each directory by its value in
      the directory's parent.
 
  INCLUDE_DIRECTORIES
      List of preprocessor include file search directories.
 
      This read-only property specifies the list of directories given so far
      to the include_directories command.  It is intended for debugging
      purposes.
 
  INCLUDE_REGULAR_EXPRESSION
      Include file scanning regular expression.
 
      This read-only property specifies the regular expression used during
      dependency scanning to match include files that should be followed.
      See the include_regular_expression command.
 
  LINK_DIRECTORIES
      List of linker search directories.
 
      This read-only property specifies the list of directories given so far
      to the link_directories command.  It is intended for debugging
      purposes.
 
  LISTFILE_STACK
      The current stack of listfiles being processed.
 
      This property is mainly useful when trying to debug errors in your
      CMake scripts.  It returns a list of what list files are currently
      being processed, in order.  So if one listfile does an INCLUDE command
      then that is effectively pushing the included listfile onto the stack.
 
  MACROS
      List of macro commands available in the current directory.
 
      This read-only property specifies the list of CMake macros currently
      defined.  It is intended for debugging purposes.  See the macro
      command.
 
  PARENT_DIRECTORY
      Source directory that added current subdirectory.
 
      This read-only property specifies the source directory that added the
      current source directory as a subdirectory of the build.  In the
      top-level directory the value is the empty-string.
 
  TEST_INCLUDE_FILE
      A cmake file that will be included when ctest is run.
 
      If you specify TEST_INCLUDE_FILE, that file will be included and
      processed when ctest is run on the directory.
 
  VARIABLES
      List of variables defined in the current directory.
 
      This read-only property specifies the list of CMake variables
      currently defined.  It is intended for debugging purposes.
 
------------------------------------------------------------------------------
Properties on Targets
 
  <CONFIG>_POSTFIX
      Postfix to append to the target file name for configuration <CONFIG>.
 
      When building with configuration <CONFIG> the value of this property
      is appended to the target file name built on disk.  For non-executable
      targets, this property is initialized by the value of the variable
      CMAKE_<CONFIG>_POSTFIX if it is set when a target is created.  This
      property is ignored on the Mac for Frameworks and App Bundles.
 
  ARCHIVE_OUTPUT_DIRECTORY
      Output directory in which to build ARCHIVE target files.
 
      This property specifies the directory into which archive target files
      should be built.  There are three kinds of target files that may be
      built: archive, library, and runtime.  Executables are always treated
      as runtime targets.  Static libraries are always treated as archive
      targets.  Module libraries are always treated as library targets.  For
      non-DLL platforms shared libraries are treated as library targets.
      For DLL platforms the DLL part of a shared library is treated as a
      runtime target and the corresponding import library is treated as an
      archive target.  All Windows-based systems including Cygwin are DLL
      platforms.  This property is initialized by the value of the variable
      CMAKE_ARCHIVE_OUTPUT_DIRECTORY if it is set when a target is created.
 
  BUILD_WITH_INSTALL_RPATH
      Should build tree targets have install tree rpaths.
 
      BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link the
      target in the build tree with the INSTALL_RPATH.  This takes
      precedence over SKIP_BUILD_RPATH and avoids the need for relinking
      before installation.
 
  CLEAN_DIRECT_OUTPUT
      Do not delete other variants of this target.
 
      When a library is built CMake by default generates code to remove any
      existing library using all possible names.  This is needed to support
      libraries that switch between STATIC and SHARED by a user option.
      However when using OUTPUT_NAME to build a static and shared library of
      the same name using different logical target names the two targets
      will remove each other's files.  This can be prevented by setting the
      CLEAN_DIRECT_OUTPUT property to 1.
 
  COMPILE_DEFINITIONS
      Preprocessor definitions for compiling a target's sources.
 
      The COMPILE_DEFINITIONS property may be set to a list of preprocessor
      definitions using the syntax VAR or VAR=value.  Function-style
      definitions are not supported.  CMake will automatically escape the
      value correctly for the native build system (note that CMake language
      syntax may require escapes to specify some values).  This property may
      be set on a per-configuration basis using the name
      COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an upper-case name (ex.
      "COMPILE_DEFINITIONS_DEBUG").
 
      CMake will automatically drop some definitions that are not supported
      by the native build tool.  The VS6 IDE does not support definitions
      with values (but NMake does).
 
      Dislaimer: Most native build tools have poor support for escaping
      certain values.  CMake has work-arounds for many cases but some values
      may just not be possible to pass correctly.  If a value does not seem
      to be escaped correctly, do not attempt to work-around the problem by
      adding escape sequences to the value.  Your work-around may break in a
      future version of CMake that has improved escape support.  Instead
      consider defining the macro in a (configured) header file.  Then
      report the limitation.
 
  COMPILE_DEFINITIONS_<CONFIG>
      Per-configuration preprocessor definitions on a target.
 
      This is the configuration-specific version of COMPILE_DEFINITIONS.
 
  COMPILE_FLAGS
      Additional flags to use when compiling this target's sources.
 
      The COMPILE_FLAGS property sets additional compiler flags used to
      build sources within the target.  Use COMPILE_DEFINITIONS to pass
      additional preprocessor definitions.
 
  DEBUG_POSTFIX
      See target property <CONFIG>_POSTFIX.
 
      This property is a special case of the more-general <CONFIG>_POSTFIX
      property for the DEBUG configuration.
 
  DEFINE_SYMBOL
      Define a symbol when compiling this target's sources.
 
      DEFINE_SYMBOL sets the name of the preprocessor symbol defined when
      compiling sources in a shared library.  If not set here then it is set
      to target_EXPORTS by default (with some substitutions if the target is
      not a valid C identifier).  This is useful for headers to know whether
      they are being included from inside their library our outside to
      properly setup dllexport/dllimport decorations.
 
  ENABLE_EXPORTS
      Specify whether an executable exports symbols for loadable modules.
 
      Normally an executable does not export any symbols because it is the
      final program.  It is possible for an executable to export symbols to
      be used by loadable modules.  When this property is set to true CMake
      will allow other targets to "link" to the executable with the
      TARGET_LINK_LIBRARIES command.  On all platforms a target-level
      dependency on the executable is created for targets that link to it.
      For non-DLL platforms the link rule is simply ignored since the
      dynamic loader will automatically bind symbols when the module is
      loaded.  For DLL platforms an import library will be created for the
      exported symbols and then used for linking.  All Windows-based systems
      including Cygwin are DLL platforms.
 
  EXCLUDE_FROM_ALL
      Exclude the target from the all target.
 
      A property on a target that indicates if the target is excluded from
      the default build target.  If it is not, then with a Makefile for
      example typing make will cause this target to be built.  The same
      concept applies to the default build of other generators.  Installing
      a target with EXCLUDE_FROM_ALL set to true has undefined behavior.
 
  EchoString
      A message to be displayed when the target is built.
 
      A message to display on some generators (such as makefiles) when the
      target is built.
 
  FRAMEWORK
      This target is a framework on the Mac.
 
      If a shared library target has this property set to true it will be
      built as a framework when built on the mac.  It will have the
      directory structure required for a framework and will be suitable to
      be used with the -framework option
 
  Fortran_MODULE_DIRECTORY
      Specify output directory for Fortran modules provided by the target.
 
      If the target contains Fortran source files that provide modules and
      the compiler supports a module output directory this specifies the
      directory in which the modules will be placed.  When this property is
      not set the modules will be placed in the build directory
      corresponding to the target's source directory.  If the variable
      CMAKE_Fortran_MODULE_DIRECTORY is set when a target is created its
      value is used to initialize this property.
 
  GENERATOR_FILE_NAME
      Generator's file for this target.
 
      An internal property used by some generators to record the name of
      project or dsp file associated with this target.
 
  HAS_CXX
      Force a target to use the CXX linker.
 
      Setting HAS_CXX on a target will force the target to use the C++
      linker (and C++ runtime libraries) for linking even if the target has
      no C++ code in it.
 
  IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
      Specify #include line transforms for dependencies in a target.
 
      This property specifies rules to transform macro-like #include lines
      during implicit dependency scanning of C and C++ source files.  The
      list of rules must be semicolon-separated with each entry of the form
      "A_MACRO(%)=value-with-%" (the % must be literal).  During dependency
      scanning occurrences of A_MACRO(...) on #include lines will be
      replaced by the value given with the macro argument substituted for
      '%'.  For example, the entry
 
        MYDIR(%)=<mydir/%>
 
      will convert lines of the form
 
        #include MYDIR(myheader.h)
 
      to
 
        #include <mydir/myheader.h>
 
      allowing the dependency to be followed.
 
      This property applies to sources in the target on which it is set.
 
  IMPORTED
      Read-only indication of whether a target is IMPORTED.
 
      The boolean value of this property is true for targets created with
      the IMPORTED option to add_executable or add_library.  It is false for
      targets built within the project.
 
  IMPORTED_CONFIGURATIONS
      Configurations provided for an IMPORTED target.
 
      Lists configuration names available for an IMPORTED target.  The names
      correspond to configurations defined in the project from which the
      target is imported.  If the importing project uses a different set of
      configurations the names may be mapped using the
      MAP_IMPORTED_CONFIG_<CONFIG> property.  Ignored for non-imported
      targets.
 
  IMPORTED_IMPLIB
      Full path to the import library for an IMPORTED target.
 
      Specifies the location of the ".lib" part of a windows DLL.  Ignored
      for non-imported targets.
 
  IMPORTED_IMPLIB_<CONFIG>
      Per-configuration version of IMPORTED_IMPLIB property.
 
      This property is used when loading settings for the <CONFIG>
      configuration of an imported target.  Configuration names correspond
      to those provided by the project from which the target is imported.
 
  IMPORTED_LINK_DEPENDENT_LIBRARIES
      Dependent shared libraries of an imported shared library.
 
      Shared libraries may be linked to other shared libraries as part of
      their implementation.  On some platforms the linker searches for the
      dependent libraries of shared libraries they are including in the
      link.  This property lists the dependent shared libraries of an
      imported library.  The list should be disjoint from the list of
      interface libraries in the IMPORTED_LINK_INTERFACE_LIBRARIES property.
      On platforms requiring dependent shared libraries to be found at link
      time CMake uses this list to add appropriate files or paths to the
      link command line.  Ignored for non-imported targets.
 
  IMPORTED_LINK_DEPENDENT_LIBRARIES_<CONFIG>
      Per-configuration version of IMPORTED_LINK_DEPENDENT_LIBRARIES.
 
      This property is used when loading settings for the <CONFIG>
      configuration of an imported target.  Configuration names correspond
      to those provided by the project from which the target is imported.
      If set, this property completely overrides the generic property for
      the named configuration.
 
  IMPORTED_LINK_INTERFACE_LIBRARIES
      Transitive link interface of an IMPORTED target.
 
      Lists libraries whose interface is included when an IMPORTED library
      target is linked to another target.  The libraries will be included on
      the link line for the target.  Unlike the LINK_INTERFACE_LIBRARIES
      property, this property applies to all imported target types,
      including STATIC libraries.  This property is ignored for non-imported
      targets.
 
  IMPORTED_LINK_INTERFACE_LIBRARIES_<CONFIG>
      Per-configuration version of IMPORTED_LINK_INTERFACE_LIBRARIES.
 
      This property is used when loading settings for the <CONFIG>
      configuration of an imported target.  Configuration names correspond
      to those provided by the project from which the target is imported.
      If set, this property completely overrides the generic property for
      the named configuration.
 
  IMPORTED_LOCATION
      Full path to the main file on disk for an IMPORTED target.
 
      Specifies the location of an IMPORTED target file on disk.  For
      executables this is the location of the executable file.  For bundles
      on OS X this is the location of the executable file inside
      Contents/MacOS under the application bundle folder.  For static
      libraries and modules this is the location of the library or module.
      For shared libraries on non-DLL platforms this is the location of the
      shared library.  For frameworks on OS X this is the location of the
      library file symlink just inside the framework folder.  For DLLs this
      is the location of the ".dll" part of the library.  For UNKNOWN
      libraries this is the location of the file to be linked.  Ignored for
      non-imported targets.
 
  IMPORTED_LOCATION_<CONFIG>
      Per-configuration version of IMPORTED_LOCATION property.
 
      This property is used when loading settings for the <CONFIG>
      configuration of an imported target.  Configuration names correspond
      to those provided by the project from which the target is imported.
 
  IMPORTED_SONAME
      The "soname" of an IMPORTED target of shared library type.
 
      Specifies the "soname" embedded in an imported shared library.  This
      is meaningful only on platforms supporting the feature.  Ignored for
      non-imported targets.
 
  IMPORTED_SONAME_<CONFIG>
      Per-configuration version of IMPORTED_SONAME property.
 
      This property is used when loading settings for the <CONFIG>
      configuration of an imported target.  Configuration names correspond
      to those provided by the project from which the target is imported.
 
  IMPORT_PREFIX
      What comes before the import library name.
 
      Similar to the target property PREFIX, but used for import libraries
      (typically corresponding to a DLL) instead of regular libraries.  A
      target property that can be set to override the prefix (such as "lib")
      on an import library name.
 
  IMPORT_SUFFIX
      What comes after the import library name.
 
      Similar to the target property SUFFIX, but used for import libraries
      (typically corresponding to a DLL) instead of regular libraries.  A
      target property that can be set to override the suffix (such as
      ".lib") on an import library name.
 
  INSTALL_NAME_DIR
      Mac OSX directory name for installed targets.
 
      INSTALL_NAME_DIR is a string specifying the directory portion of the
      "install_name" field of shared libraries on Mac OSX to use in the
      installed targets.
 
  INSTALL_RPATH
      The rpath to use for installed targets.
 
      A semicolon-separated list specifying the rpath to use in installed
      targets (for platforms that support it).
 
  INSTALL_RPATH_USE_LINK_PATH
      Add paths to linker search and installed rpath.
 
      INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true will
      append directories in the linker search path and outside the project
      to the INSTALL_RPATH.
 
  LIBRARY_OUTPUT_DIRECTORY
      Output directory in which to build LIBRARY target files.
 
      This property specifies the directory into which library target files
      should be built.  There are three kinds of target files that may be
      built: archive, library, and runtime.  Executables are always treated
      as runtime targets.  Static libraries are always treated as archive
      targets.  Module libraries are always treated as library targets.  For
      non-DLL platforms shared libraries are treated as library targets.
      For DLL platforms the DLL part of a shared library is treated as a
      runtime target and the corresponding import library is treated as an
      archive target.  All Windows-based systems including Cygwin are DLL
      platforms.  This property is initialized by the value of the variable
      CMAKE_LIBRARY_OUTPUT_DIRECTORY if it is set when a target is created.
 
  LINKER_LANGUAGE
      What tool to use for linking, based on language.
 
      The LINKER_LANGUAGE property is used to change the tool used to link
      an executable or shared library.  The default is set the language to
      match the files in the library.  CXX and C are common values for this
      property.
 
  LINK_FLAGS
      Additional flags to use when linking this target.
 
      The LINK_FLAGS property can be used to add extra flags to the link
      step of a target.  LINK_FLAGS_<CONFIG> will add to the configuration
      <CONFIG>, for example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO.
 
  LINK_FLAGS_<CONFIG>
      Per-configuration linker flags for a target.
 
      This is the configuration-specific version of LINK_FLAGS.
 
  LINK_INTERFACE_LIBRARIES
      List public interface libraries for a shared library or executable.
 
      By default linking to a shared library target transitively links to
      targets with which the library itself was linked.  For an executable
      with exports (see the ENABLE_EXPORTS property) no default transitive
      link dependencies are used.  This property replaces the default
      transitive link dependencies with an explict list.  When the target is
      linked into another target the libraries listed (and recursively their
      link interface libraries) will be provided to the other target also.
      If the list is empty then no transitive link dependencies will be
      incorporated when this target is linked into another target even if
      the default set is non-empty.  This property is ignored for STATIC
      libraries.
 
  LINK_INTERFACE_LIBRARIES_<CONFIG>
      Per-configuration list of public interface libraries for a target.
 
      This is the configuration-specific version of
      LINK_INTERFACE_LIBRARIES.  If set, this property completely overrides
      the generic property for the named configuration.
 
  LINK_SEARCH_END_STATIC
      End a link line such that static system libraries are used.
 
      Some linkers support switches such as -Bstatic and -Bdynamic to
      determine whether to use static or shared libraries for -lXXX options.
      CMake uses these options to set the link type for libraries whose full
      paths are not known or (in some cases) are in implicit link
      directories for the platform.  By default the linker search type is
      left at -Bdynamic by the end of the library list.  This property
      switches the final linker search type to -Bstatic.
 
  LOCATION
      Read-only location of a target on disk.
 
      For an imported target, this read-only property returns the value of
      the LOCATION_<CONFIG> property for an unspecified configuration
      <CONFIG> provided by the target.
 
      For a non-imported target, this property is provided for compatibility
      with CMake 2.4 and below.  It was meant to get the location of an
      executable target's output file for use in add_custom_command.  The
      path may contain a build-system-specific portion that is replaced at
      build time with the configuration getting built (such as
      "$(ConfigurationName)" in VS).  In CMake 2.6 and above
      add_custom_command automatically recognizes a target name in its
      COMMAND and DEPENDS options and computes the target location.
      Therefore this property is not needed for creating custom commands.
 
  LOCATION_<CONFIG>
      Read-only property providing a target location on disk.
 
      A read-only property that indicates where a target's main file is
      located on disk for the configuration <CONFIG>.  The property is
      defined only for library and executable targets.  An imported target
      may provide a set of configurations different from that of the
      importing project.  By default CMake looks for an exact-match but
      otherwise uses an arbitrary available configuration.  Use the
      MAP_IMPORTED_CONFIG_<CONFIG> property to map imported configurations
      explicitly.
 
  MACOSX_BUNDLE
      Build an executable as an application bundle on Mac OS X.
 
      When this property is set to true the executable when built on Mac OS
      X will be created as an application bundle.  This makes it a GUI
      executable that can be launched from the Finder.  See the
      MACOSX_BUNDLE_INFO_PLIST target property for information about
      creation of the Info.plist file for the application bundle.
 
  MACOSX_BUNDLE_INFO_PLIST
      Specify a custom Info.plist template for a Mac OS X App Bundle.
 
      An executable target with MACOSX_BUNDLE enabled will be built as an
      application bundle on Mac OS X.  By default its Info.plist file is
      created by configuring a template called MacOSXBundleInfo.plist.in
      located in the CMAKE_MODULE_PATH.  This property specifies an
      alternative template file name which may be a full path.
 
      The following target properties may be set to specify content to be
      configured into the file:
 
        MACOSX_BUNDLE_INFO_STRING
        MACOSX_BUNDLE_ICON_FILE
        MACOSX_BUNDLE_GUI_IDENTIFIER
        MACOSX_BUNDLE_LONG_VERSION_STRING
        MACOSX_BUNDLE_BUNDLE_NAME
        MACOSX_BUNDLE_SHORT_VERSION_STRING
        MACOSX_BUNDLE_BUNDLE_VERSION
        MACOSX_BUNDLE_COPYRIGHT
 
      CMake variables of the same name may be set to affect all targets in a
      directory that do not have each specific property set.  If a custom
      Info.plist is specified by this property it may of course hard-code
      all the settings instead of using the target properties.
 
  MACOSX_FRAMEWORK_INFO_PLIST
      Specify a custom Info.plist template for a Mac OS X Framework.
 
      An library target with FRAMEWORK enabled will be built as a framework
      on Mac OS X.  By default its Info.plist file is created by configuring
      a template called MacOSXFrameworkInfo.plist.in located in the
      CMAKE_MODULE_PATH.  This property specifies an alternative template
      file name which may be a full path.
 
      The following target properties may be set to specify content to be
      configured into the file:
 
        MACOSX_FRAMEWORK_ICON_FILE
        MACOSX_FRAMEWORK_IDENTIFIER
        MACOSX_FRAMEWORK_SHORT_VERSION_STRING
        MACOSX_FRAMEWORK_BUNDLE_VERSION
 
      CMake variables of the same name may be set to affect all targets in a
      directory that do not have each specific property set.  If a custom
      Info.plist is specified by this property it may of course hard-code
      all the settings instead of using the target properties.
 
  MAP_IMPORTED_CONFIG_<CONFIG>
      Map from project configuration to IMPORTED target's configuration.
 
      List configurations of an imported target that may be used for the
      current project's <CONFIG> configuration.  Targets imported from
      another project may not provide the same set of configuration names
      available in the current project.  Setting this property tells CMake
      what imported configurations are suitable for use when building the
      <CONFIG> configuration.  The first configuration in the list found to
      be provided by the imported target is selected.  If no matching
      configurations are available the imported target is considered to be
      not found.  This property is ignored for non-imported targets.
 
  OUTPUT_NAME
      Sets the real name of a target when it is built.
 
      Sets the real name of a target when it is built and can be used to
      help create two targets of the same name even though CMake requires
      unique logical target names.  There is also a <CONFIG>_OUTPUT_NAME
      that can set the output name on a per-configuration basis.
 
  POST_INSTALL_SCRIPT
      Deprecated install support.
 
      The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old
      way to specify CMake scripts to run before and after installing a
      target.  They are used only when the old INSTALL_TARGETS command is
      used to install the target.  Use the INSTALL command instead.
 
  PREFIX
      What comes before the library name.
 
      A target property that can be set to override the prefix (such as
      "lib") on a library name.
 
  PRE_INSTALL_SCRIPT
      Deprecated install support.
 
      The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old
      way to specify CMake scripts to run before and after installing a
      target.  They are used only when the old INSTALL_TARGETS command is
      used to install the target.  Use the INSTALL command instead.
 
  PRIVATE_HEADER
      Specify private header files in a FRAMEWORK shared library target.
 
      Shared library targets marked with the FRAMEWORK property generate
      frameworks on OS X and normal shared libraries on other platforms.
      This property may be set to a list of header files to be placed in the
      PrivateHeaders directory inside the framework folder.  On non-Apple
      platforms these headers may be installed using the PRIVATE_HEADER
      option to the install(TARGETS) command.
 
  PROJECT_LABEL
      Change the name of a target in an IDE.
 
      Can be used to change the name of the target in an IDE like visual
      stuido.
 
  PUBLIC_HEADER
      Specify public header files in a FRAMEWORK shared library target.
 
      Shared library targets marked with the FRAMEWORK property generate
      frameworks on OS X and normal shared libraries on other platforms.
      This property may be set to a list of header files to be placed in the
      Headers directory inside the framework folder.  On non-Apple platforms
      these headers may be installed using the PUBLIC_HEADER option to the
      install(TARGETS) command.
 
  RESOURCE
      Specify resource files in a FRAMEWORK shared library target.
 
      Shared library targets marked with the FRAMEWORK property generate
      frameworks on OS X and normal shared libraries on other platforms.
      This property may be set to a list of files to be placed in the
      Resources directory inside the framework folder.  On non-Apple
      platforms these files may be installed using the RESOURCE option to
      the install(TARGETS) command.
 
  RUNTIME_OUTPUT_DIRECTORY
      Output directory in which to build RUNTIME target files.
 
      This property specifies the directory into which runtime target files
      should be built.  There are three kinds of target files that may be
      built: archive, library, and runtime.  Executables are always treated
      as runtime targets.  Static libraries are always treated as archive
      targets.  Module libraries are always treated as library targets.  For
      non-DLL platforms shared libraries are treated as library targets.
      For DLL platforms the DLL part of a shared library is treated as a
      runtime target and the corresponding import library is treated as an
      archive target.  All Windows-based systems including Cygwin are DLL
      platforms.  This property is initialized by the value of the variable
      CMAKE_RUNTIME_OUTPUT_DIRECTORY if it is set when a target is created.
 
  SKIP_BUILD_RPATH
      Should rpaths be used for the build tree.
 
      SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic
      generation of an rpath allowing the target to run from the build tree.
 
  SOURCES
      Source names specified for a target.
 
      Read-only list of sources specified for a target.  The names returned
      are suitable for passing to the set_source_files_properties command.
 
  SOVERSION
      What version number is this target.
 
      For shared libraries VERSION and SOVERSION can be used to specify the
      build version and api version respectively.  When building or
      installing appropriate symlinks are created if the platform supports
      symlinks and the linker supports so-names.  If only one of both is
      specified the missing is assumed to have the same version number.  For
      shared libraries and executables on Windows the VERSION attribute is
      parsed to extract a "major.minor" version number.  These numbers are
      used as the image version of the binary.
 
  STATIC_LIBRARY_FLAGS
      Extra flags to use when linking static libraries.
 
      Extra flags to use when linking a static library.
 
  SUFFIX
      What comes after the library name.
 
      A target property that can be set to override the suffix (such as
      ".so") on a library name.
 
  TYPE
      The type of the target.
 
      This read-only property can be used to test the type of the given
      target.  It will be one of STATIC_LIBRARY, MODULE_LIBRARY,
      SHARED_LIBRARY, EXECUTABLE or one of the internal target types.
 
  VERSION
      What version number is this target.
 
      For shared libraries VERSION and SOVERSION can be used to specify the
      build version and api version respectively.  When building or
      installing appropriate symlinks are created if the platform supports
      symlinks and the linker supports so-names.  If only one of both is
      specified the missing is assumed to have the same version number.  For
      executables VERSION can be used to specify the build version.  When
      building or installing appropriate symlinks are created if the
      platform supports symlinks.  For shared libraries and executables on
      Windows the VERSION attribute is parsed to extract a "major.minor"
      version number.  These numbers are used as the image version of the
      binary.
 
  VS_KEYWORD
      Visual Studio project keyword.
 
      Can be set to change the visual studio keyword, for example QT
      integration works better if this is set to Qt4VSv1.0.
 
  VS_SCC_LOCALPATH
      Visual Studio Source Code Control Provider.
 
      Can be set to change the visual studio source code control local path
      property.
 
  VS_SCC_PROJECTNAME
      Visual Studio Source Code Control Project.
 
      Can be set to change the visual studio source code control project
      name property.
 
  VS_SCC_PROVIDER
      Visual Studio Source Code Control Provider.
 
      Can be set to change the visual studio source code control provider
      property.
 
  WIN32_EXECUTABLE
      Build an executable with a WinMain entry point on windows.
 
      When this property is set to true the executable when linked on
      Windows will be created with a WinMain() entry point instead of of
      just main().This makes it a GUI executable instead of a console
      application.  See the CMAKE_MFC_FLAG variable documentation to
      configure use of MFC for WinMain executables.
 
  XCODE_ATTRIBUTE_<an-attribute>
      Set Xcode target attributes directly.
 
      Tell the Xcode generator to set '<an-attribute>' to a given value in
      the generated Xcode project.  Ignored on other generators.
 
------------------------------------------------------------------------------
Properties on Tests
 
  FAIL_REGULAR_EXPRESSION
      If the output matches this regular expression the test will fail.
 
      If set, if the output matches one of specified regular expressions,
      the test will fail.For example: PASS_REGULAR_EXPRESSION
      "[^a-z]Error;ERROR;Failed"
 
  MEASUREMENT
      Specify a DART measurement and value to be reported for a test.
 
      If set to a name then that name will be reported to DART as a named
      measurement with a value of 1.  You may also specify a value by
      setting MEASUREMENT to "measurement=value".
 
  PASS_REGULAR_EXPRESSION
      The output must match this regular expression for the test to pass.
 
      If set, the test output will be checked against the specified regular
      expressions and at least one of the regular expressions has to match,
      otherwise the test will fail.
 
  TIMEOUT
      How many seconds to allow for this test.
 
      This property if set will limit a test to not take more than the
      specified number of seconds to run.  If it exceeds that the test
      process will be killed and ctest will move to the next test.  This
      setting takes precedence over DART_TESTING_TIMEOUT and
      CTEST_TESTING_TIMEOUT.
 
  WILL_FAIL
      If set to true, this will invert the pass/fail flag of the test.
 
      This property can be used for tests that are expected to fail and
      return a non zero return code.
 
------------------------------------------------------------------------------
Properties on Source Files
 
  ABSTRACT
      Is this source file an abstract class.
 
      A property on a source file that indicates if the source file
      represents a class that is abstract.  This only makes sense for
      languages that have a notion of an abstract class and it is only used
      by some tools that wrap classes into other languages.
 
  COMPILE_DEFINITIONS
      Preprocessor definitions for compiling a source file.
 
      The COMPILE_DEFINITIONS property may be set to a list of preprocessor
      definitions using the syntax VAR or VAR=value.  Function-style
      definitions are not supported.  CMake will automatically escape the
      value correctly for the native build system (note that CMake language
      syntax may require escapes to specify some values).  This property may
      be set on a per-configuration basis using the name
      COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an upper-case name (ex.
      "COMPILE_DEFINITIONS_DEBUG").
 
      CMake will automatically drop some definitions that are not supported
      by the native build tool.  The VS6 IDE does not support definitions
      with values (but NMake does).  Xcode does not support
      per-configuration definitions on source files.
 
      Dislaimer: Most native build tools have poor support for escaping
      certain values.  CMake has work-arounds for many cases but some values
      may just not be possible to pass correctly.  If a value does not seem
      to be escaped correctly, do not attempt to work-around the problem by
      adding escape sequences to the value.  Your work-around may break in a
      future version of CMake that has improved escape support.  Instead
      consider defining the macro in a (configured) header file.  Then
      report the limitation.
 
  COMPILE_DEFINITIONS_<CONFIG>
      Per-configuration preprocessor definitions on a source file.
 
      This is the configuration-specific version of COMPILE_DEFINITIONS.
      Note that Xcode does not support per-configuration source file flags
      so this property will be ignored by the Xcode generator.
 
  COMPILE_FLAGS
      Additional flags to be added when compiling this source file.
 
      These flags will be added to the list of compile flags when this
      source file builds.  Use COMPILE_DEFINITIONS to pass additional
      preprocessor definitions.
 
  EXTERNAL_OBJECT
      If set to true then this is an object file.
 
      If this property is set to true then the source file is really an
      object file and should not be compiled.  It will still be linked into
      the target though.
 
  GENERATED
      Is this source file generated as part of the build process.
 
      If a source file is generated by the build process CMake will handle
      it differently in temrs of dependency checking etc.  Otherwise having
      a non-existent source file could create problems.
 
  HEADER_FILE_ONLY
      Is this source file only a header file.
 
      A property on a source file that indicates if the source file is a
      header file with no associated implementation.  This is set
      automatically based on the file extension and is used by CMake to
      determine is certain dependency information should be computed.
 
  KEEP_EXTENSION
      Make the output file have the same extension as the source file.
 
      If this property is set then the file extension of the output file
      will be the same as that of the source file.  Normally the output file
      extension is computed based on the language of the source file, for
      example .cxx will go to a .o extension.
 
  LANGUAGE
      What programming language is the file.
 
      A property that can be set to indicate what programming language the
      source file is.  If it is not set the language is determined based on
      the file extension.  Typical values are CXX C etc.
 
  LOCATION
      The full path to a source file.
 
      A read only property on a SOURCE FILE that contains the full path to
      the source file.
 
  MACOSX_PACKAGE_LOCATION
      Place a source file inside a Mac OS X bundle or framework.
 
      Executable targets with the MACOSX_BUNDLE property set are built as
      Mac OS X application bundles on Apple platforms.  Shared library
      targets with the FRAMEWORK property set are built as Mac OS X
      frameworks on Apple platforms.  Source files listed in the target with
      this property set will be copied to a directory inside the bundle or
      framework content folder specified by the property value.  For bundles
      the content folder is "<name>.app/Contents".  For frameworks the
      content folder is "<name>.framework/Versions/<version>".  See the
      PUBLIC_HEADER, PRIVATE_HEADER, and RESOURCE target properties for
      specifying files meant for Headers, PrivateHeadres, or Resources
      directories.
 
  OBJECT_DEPENDS
      Additional files on which a compiled object file depends.
 
      Specifies a semicolon-separated list of full-paths to files on which
      any object files compiled from this source file depend.  An object
      file will be recompiled if any of the named files is newer than it.
 
      This property need not be used to specify the dependency of a source
      file on a generated header file that it includes.  Although the
      property was originally introduced for this purpose, it is no longer
      necessary.  If the generated header file is created by a custom
      command in the same target as the source file, the automatic
      dependency scanning process will recognize the dependency.  If the
      generated header file is created by another target, an inter-target
      dependency should be created with the add_dependencies command (if one
      does not already exist due to linking relationships).
 
  OBJECT_OUTPUTS
      Additional outputs for a Makefile rule.
 
      Additional outputs created by compilation of this source file.  If any
      of these outputs is missing the object will be recompiled.  This is
      supported only on Makefile generators and will be ignored on other
      generators.
 
  SYMBOLIC
      Is this just a name for a rule.
 
      If SYMBOLIC (boolean) is set to true the build system will be informed
      that the source file is not actually created on disk but instead used
      as a symbolic name for a build rule.
 
  WRAP_EXCLUDE
      Exclude this source file from any code wrapping techniques.
 
      Some packages can wrap source files into alternate languages to
      provide additional functionality.  For example, C++ code can be
      wrapped into Java or Python etc using SWIG etc.  If WRAP_EXCLUDE is
      set to true (1 etc) that indicates then this source file should not be
      wrapped.
 
------------------------------------------------------------------------------
Compatibility Commands
 
  CMake Compatibility Listfile Commands - Obsolete commands supported by CMake for compatibility.
 
This is the documentation for now obsolete listfile commands from previous
CMake versions, which are still supported for compatibility reasons.  You
should instead use the newer, faster and shinier new commands.  ;-)
 
  build_name
      Deprecated.  Use ${CMAKE_SYSTEM} and ${CMAKE_CXX_COMPILER} instead.
 
        build_name(variable)
 
      Sets the specified variable to a string representing the platform and
      compiler settings.  These values are now available through the
      CMAKE_SYSTEM and CMAKE_CXX_COMPILER variables.
 
  exec_program
      Deprecated.  Use the execute_process() command instead.
 
      Run an executable program during the processing of the CMakeList.txt
      file.
 
        exec_program(Executable [directory in which to run]
                      [ARGS <arguments to executable>]
                      [OUTPUT_VARIABLE <var>]
                      [RETURN_VALUE <var>])
 
      The executable is run in the optionally specified directory.  The
      executable can include arguments if it is double quoted, but it is
      better to use the optional ARGS argument to specify arguments to the
      program.  This is because cmake will then be able to escape spaces in
      the executable path.  An optional argument OUTPUT_VARIABLE specifies a
      variable in which to store the output.  To capture the return value of
      the execution, provide a RETURN_VALUE.  If OUTPUT_VARIABLE is
      specified, then no output will go to the stdout/stderr of the console
      running cmake.
 
 
  export_library_dependencies
      Deprecated.  Use INSTALL(EXPORT) or EXPORT command.
 
      This command generates an old-style library dependencies file.
      Projects requiring CMake 2.6 or later should not use the command.  Use
      instead the install(EXPORT) command to help export targets from an
      installation tree and the export() command to export targets from a
      build tree.
 
      The old-style library dependencies file does not take into account
      per-configuration names of libraries or the LINK_INTERFACE_LIBRARIES
      target property.
 
        export_library_dependencies(<file> [APPEND])
 
      Create a file named <file> that can be included into a CMake listfile
      with the INCLUDE command.  The file will contain a number of SET
      commands that will set all the variables needed for library dependency
      information.  This should be the last command in the top level
      CMakeLists.txt file of the project.  If the APPEND option is
      specified, the SET commands will be appended to the given file instead
      of replacing it.
 
  install_files
      Deprecated.  Use the install(FILES ) command instead.
 
      This command has been superceded by the install command.  It is
      provided for compatibility with older CMake code.  The FILES form is
      directly replaced by the FILES form of the install command.  The
      regexp form can be expressed more clearly using the GLOB form of the
      file command.
 
        install_files(<dir> extension file file ...)
 
      Create rules to install the listed files with the given extension into
      the given directory.  Only files existing in the current source tree
      or its corresponding location in the binary tree may be listed.  If a
      file specified already has an extension, that extension will be
      removed first.  This is useful for providing lists of source files
      such as foo.cxx when you want the corresponding foo.h to be installed.
      A typical extension is '.h'.
 
        install_files(<dir> regexp)
 
      Any files in the current source directory that match the regular
      expression will be installed.
 
        install_files(<dir> FILES file file ...)
 
      Any files listed after the FILES keyword will be installed explicitly
      from the names given.  Full paths are allowed in this form.
 
      The directory <dir> is relative to the installation prefix, which is
      stored in the variable CMAKE_INSTALL_PREFIX.
 
  install_programs
      Deprecated.  Use the install(PROGRAMS ) command instead.
 
      This command has been superceded by the install command.  It is
      provided for compatibility with older CMake code.  The FILES form is
      directly replaced by the PROGRAMS form of the INSTALL command.  The
      regexp form can be expressed more clearly using the GLOB form of the
      FILE command.
 
        install_programs(<dir> file1 file2 [file3 ...])
        install_programs(<dir> FILES file1 [file2 ...])
 
      Create rules to install the listed programs into the given directory.
      Use the FILES argument to guarantee that the file list version of the
      command will be used even when there is only one argument.
 
        install_programs(<dir> regexp)
 
      In the second form any program in the current source directory that
      matches the regular expression will be installed.
 
      This command is intended to install programs that are not built by
      cmake, such as shell scripts.  See the TARGETS form of the INSTALL
      command to create installation rules for targets built by cmake.
 
      The directory <dir> is relative to the installation prefix, which is
      stored in the variable CMAKE_INSTALL_PREFIX.
 
  install_targets
      Deprecated.  Use the install(TARGETS ) command instead.
 
      This command has been superceded by the install command.  It is
      provided for compatibility with older CMake code.
 
        install_targets(<dir> [RUNTIME_DIRECTORY dir] target target)
 
      Create rules to install the listed targets into the given directory.
      The directory <dir> is relative to the installation prefix, which is
      stored in the variable CMAKE_INSTALL_PREFIX.  If RUNTIME_DIRECTORY is
      specified, then on systems with special runtime files (Windows DLL),
      the files will be copied to that directory.
 
  link_libraries
      Deprecated.  Use the target_link_libraries() command instead.
 
      Link libraries to all targets added later.
 
        link_libraries(library1 <debug | optimized> library2 ...)
 
      Specify a list of libraries to be linked into any following targets
      (typically added with the add_executable or add_library calls).  This
      command is passed down to all subdirectories.  The debug and optimized
      strings may be used to indicate that the next library listed is to be
      used only for that specific type of build.
 
  make_directory
      Deprecated.  Use the file(MAKE_DIRECTORY ) command instead.
 
        make_directory(directory)
 
      Creates the specified directory.  Full paths should be given.  Any
      parent directories that do not exist will also be created.  Use with
      care.
 
  remove
      Deprecated.  Use the list(REMOVE_ITEM ) command instead.
 
        remove(VAR VALUE VALUE ...)
 
      Removes VALUE from the variable VAR.  This is typically used to remove
      entries from a vector (e.g.  semicolon separated list).  VALUE is
      expanded.
 
  subdir_depends
      Deprecated.  Does nothing.
 
        subdir_depends(subdir dep1 dep2 ...)
 
      Does not do anything.  This command used to help projects order
      parallel builds correctly.  This functionality is now automatic.
 
  subdirs
      Deprecated.  Use the add_subdirectory() command instead.
 
      Add a list of subdirectories to the build.
 
        subdirs(dir1 dir2 ...[EXCLUDE_FROM_ALL exclude_dir1 exclude_dir2 ...] [PREORDER] )
 
      Add a list of subdirectories to the build.  The add_subdirectory
      command should be used instead of subdirs although subdirs will still
      work.  This will cause any CMakeLists.txt files in the sub directories
      to be processed by CMake.  Any directories after the PREORDER flag are
      traversed first by makefile builds, the PREORDER flag has no effect on
      IDE projects.  Any directories after the EXCLUDE_FROM_ALL marker will
      not be included in the top level makefile or project file.  This is
      useful for having CMake create makefiles or projects for a set of
      examples in a project.  You would want CMake to generate makefiles or
      project files for all the examples at the same time, but you would not
      want them to show up in the top level project or be built each time
      make is run from the top.
 
  use_mangled_mesa
      Copy mesa headers for use in combination with system GL.
 
        use_mangled_mesa(PATH_TO_MESA OUTPUT_DIRECTORY)
 
      The path to mesa includes, should contain gl_mangle.h.  The mesa
      headers are copied to the specified output directory.  This allows
      mangled mesa headers to override other GL headers by being added to
      the include directory path earlier.
 
  utility_source
      Specify the source tree of a third-party utility.
 
        utility_source(cache_entry executable_name
                        path_to_source [file1 file2 ...])
 
      When a third-party utility's source is included in the distribution,
      this command specifies its location and name.  The cache entry will
      not be set unless the path_to_source and all listed files exist.  It
      is assumed that the source tree of the utility will have been built
      before it is needed.
 
      When cross compiling CMake will print a warning if a utility_source()
      command is executed, because in many cases it is used to build an
      executable which is executed later on.  This doesn't work when cross
      compiling, since the executable can run only on their target platform.
      So in this case the cache entry has to be adjusted manually so it
      points to an executable which is runnable on the build host.
 
  variable_requires
      Deprecated.  Use the if() command instead.
 
      Assert satisfaction of an option's required variables.
 
        variable_requires(TEST_VARIABLE RESULT_VARIABLE
                          REQUIRED_VARIABLE1
                          REQUIRED_VARIABLE2 ...)
 
      The first argument (TEST_VARIABLE) is the name of the variable to be
      tested, if that variable is false nothing else is done.  If
      TEST_VARIABLE is true, then the next argument (RESULT_VARIABLE) is a
      variable that is set to true if all the required variables are set.
      The rest of the arguments are variables that must be true or not set
      to NOTFOUND to avoid an error.  If any are not true, an error is
      reported.
 
  write_file
      Deprecated.  Use the file(WRITE ) command instead.
 
        write_file(filename "message to write"... [APPEND])
 
      The first argument is the file name, the rest of the arguments are
      messages to write.  If the argument APPEND is specified, then the
      message will be appended.
 
      NOTE 1: file(WRITE ...  and file(APPEND ...  do exactly the same as
      this one but add some more functionality.
 
      NOTE 2: When using write_file the produced file cannot be used as an
      input to CMake (CONFIGURE_FILE, source file ...) because it will lead
      to an infinite loop.  Use configure_file if you want to generate input
      files to CMake.

The following modules are provided with CMake.  They can be used with
INCLUDE(ModuleName).
 
  CMake Modules - Modules coming with CMake, the Cross-Platform Makefile Generator.
 
This is the documentation for the modules and scripts coming with CMake.
Using these modules you can check the computer system for installed software
packages, features of the compiler and the existance of headers to name just
a few.
 
  AddFileDependencies
      ADD_FILE_DEPENDENCIES(source_file depend_files...)
 
      Adds the given files as dependencies to source_file

      A collection of CMake utility functions useful for dealing with .app
      bundles on the Mac and bundle-like directories on any OS.
 
      The following functions are provided by this script:
 
          get_bundle_main_executable
          get_dotapp_dir
          get_bundle_and_executable
          get_bundle_all_executables
          get_item_key
          clear_bundle_keys
          set_bundle_key_values
          get_bundle_keys
          copy_resolved_item_into_bundle
          fixup_bundle_item
          fixup_bundle
          copy_and_fixup_bundle
          verify_bundle_prerequisites
          verify_bundle_symlinks
          verify_app
 
     
 
      Requires CMake 2.6 or greater because it uses function, break and
      PARENT_SCOPE.  Also depends on GetPrerequisites.cmake.
 
  CMakeASM-ATTInformation
       
 
      support for AT&T syntax assemblers, e.g.  GNU as
 
  CMakeASM_MASMInformation
       
 
      support for the MS assembler, masm and masm64
 
  CMakeBackwardCompatibilityCXX
      define a bunch of backwards compatibility variables
 
        CMAKE_ANSI_CXXFLAGS - flag for ansi c++
        CMAKE_HAS_ANSI_STRING_STREAM - has <strstream>
        INCLUDE(TestForANSIStreamHeaders)
        INCLUDE(CheckIncludeFileCXX)
        INCLUDE(TestForSTDNamespace)
        INCLUDE(TestForANSIForScope)
 
 
  CMakeDependentOption
      Macro to provide an option dependent on other options.
 
      This macro presents an option to the user only if a set of other
      conditions are true.  When the option is not presented a default value
      is used, but any value set by the user is preserved for when the
      option is presented again.  Example invocation:
 
        CMAKE_DEPENDENT_OPTION(USE_FOO "Use Foo" ON
                                "USE_BAR;NOT USE_ZOT" OFF)
 
      If USE_BAR is true and USE_ZOT is false, this provides an option
      called USE_FOO that defaults to ON.  Otherwise, it sets USE_FOO to
      OFF.  If the status of USE_BAR or USE_ZOT ever changes, any value for
      the USE_FOO option is saved so that when the option is re-enabled it
      retains its old value.
 
  CMakeDetermineASM-ATTCompiler
       
 
      determine the compiler to use for ASM using AT&T syntax, e.g.  GNU as
 
  CMakeDetermineASMCompiler
       
 
      determine the compiler to use for ASM programs
 
  CMakeDetermineASM_MASMCompiler
       
 
      Find the MS assembler (masm or masm64)
 
  CMakeExportBuildSettings
      export build settings from a project.
 
        CMAKE_EXPORT_BUILD_SETTINGS(SETTINGS_FILE)
 
      macro defined to export the build settings for use by another project.
 
        SETTINGS_FILE - the file into which the settings are to be stored.
 
 
  CMakeFindFrameworks
      helper module to find OSX frameworks
 
  CMakeForceCompiler
       
 
      This module defines macros intended for use by cross-compiling
      toolchain files when CMake is not able to automatically detect the
      compiler identification.
 
      Macro CMAKE_FORCE_C_COMPILER has the following signature:
 
          CMAKE_FORCE_C_COMPILER(<compiler> <compiler-id>)
 
      It sets CMAKE_C_COMPILER to the given compiler and the cmake internal
      variable CMAKE_C_COMPILER_ID to the given compiler-id.  It also
      bypasses the check for working compiler and basic compiler information
      tests.
 
      Macro CMAKE_FORCE_CXX_COMPILER has the following signature:
 
          CMAKE_FORCE_CXX_COMPILER(<compiler> <compiler-id>)
 
      It sets CMAKE_CXX_COMPILER to the given compiler and the cmake
      internal variable CMAKE_CXX_COMPILER_ID to the given compiler-id.  It
      also bypasses the check for working compiler and basic compiler
      information tests.
 
      So a simple toolchain file could look like this:
 
          INCLUDE (CMakeForceCompiler)
          SET(CMAKE_SYSTEM_NAME Generic)
          CMAKE_FORCE_C_COMPILER  (chc12 MetrowerksHicross)
          CMAKE_FORCE_CXX_COMPILER (chc12 MetrowerksHicross)
 
 
  CMakeImportBuildSettings
      import build settings from another project
 
        CMAKE_IMPORT_BUILD_SETTINGS(SETTINGS_FILE)
 
      macro defined to import the build settings from another project.
      SETTINGS_FILE is a file created by the other project's call to the
      CMAKE_EXPORT_BUILD_SETTINGS macro, see CMakeExportBuildSettings.
 
  CMakeJavaInformation
       
 
      This should be included before the _INIT variables are used to
      initialize the cache.  Since the rule variables have if blocks on
      them, users can still define them here.  But, it should still be after
      the platform file so changes can be made to those values.
 
  CMakePrintSystemInformation
      print system information
 
      This file can be used for diagnostic purposes just include it in a
      project to see various internal CMake variables.
 
  CPack
      Build binary and source package installers
 
     
 
      The CPack module generates binary and source installers in a variety
      of formats using the cpack program.  Inclusion of the CPack module
      adds two new targets to the resulting makefiles, package and
      package_source, which build the binary and source installers,
      respectively.  The generated binary installers contain everything
      installed via CMake's INSTALL command (and the deprecated
      INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS commands).
 
      For certain kinds of binary installers (including the graphical
      installers on Mac OS X and Windows), CPack generates installers that
      allow users to select individual application components to install.
      The contents of each of the components are identified by the COMPONENT
      argument of CMake's INSTALL command.  These components can be
      annotated with user-friendly names and descriptions, inter-component
      dependencies, etc., and grouped in various ways to customize the
      resulting installer.  See the cpack_add_* commands, described below,
      for more information about component-specific installations.
 
      Before including the CPack module, there are a variety of variables
      that can be set to customize the resulting installers.  The most
      commonly-used variables are:
 
          CPACK_PACKAGE_NAME - The name of the package (or application). If
          not specified, defaults to the project name.
 
     
 
          CPACK_PACKAGE_VENDOR - The name of the package vendor (e.g.,
          "Kitware").
 
     
 
          CPACK_PACKAGE_VERSION_MAJOR - Package major Version
 
     
 
          CPACK_PACKAGE_VERSION_MINOR - Package minor Version
 
     
 
          CPACK_PACKAGE_VERSION_PATCH - Package patch Version
 
     
 
          CPACK_PACKAGE_DESCRIPTION_FILE - A text file used to describe the
          project. Used, for example, the introduction screen of a
          CPack-generated Windows installer to describe the project.
 
     
 
          CPACK_PACKAGE_DESCRIPTION_SUMMARY - Short description of the
          project (only a few words).
 
     
 
          CPACK_PACKAGE_FILE_NAME - The name of the package file to generate,
          not including the extension. For example, cmake-2.6.1-Linux-i686.
 
     
 
          CPACK_PACKAGE_INSTALL_DIRECTORY - Installation directory on the
          target system, e.g., "CMake 2.5".
 
     
 
          CPACK_RESOURCE_FILE_LICENSE - License file for the project, which
          will typically be displayed to the user (often with an explicit
          "Accept" button, for graphical installers) prior to installation.
 
     
 
          CPACK_RESOURCE_FILE_README - ReadMe file for the project, which
          typically describes in some detail
 
     
 
          CPACK_RESOURCE_FILE_WELCOME - Welcome file for the project, which
          welcomes users to this installer. Typically used in the graphical
          installers on Windows and Mac OS X.
 
     
 
          CPACK_MONOLITHIC_INSTALL - Disables the component-based
          installation mechanism, so that all components are always installed.
 
     
 
          CPACK_GENERATOR - List of CPack generators to use. If not
          specified, CPack will create a set of options (e.g.,
          CPACK_BINARY_NSIS) allowing the user to enable/disable individual
          generators.
 
     
 
          CPACK_OUTPUT_CONFIG_FILE - The name of the CPack configuration file
          for binary installers that will be generated by the CPack
          module. Defaults to CPackConfig.cmake.
 
     
 
          CPACK_PACKAGE_EXECUTABLES - Lists each of the executables along
          with a text label, to be used to create Start Menu shortcuts on
          Windows. For example, setting this to the list ccmake;CMake will
          create a shortcut named "CMake" that will execute the installed
          executable ccmake.
 
     
 
          CPACK_STRIP_FILES - List of files to be stripped. Starting with
          CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which
          enables stripping of all files (a list of files evaluates to TRUE
          in CMake, so this change is compatible).
 
     
 
      The following CPack variables are specific to source packages, and
      will not affect binary packages:
 
          CPACK_SOURCE_PACKAGE_FILE_NAME - The name of the source package,
          e.g., cmake-2.6.1
 
     
 
          CPACK_SOURCE_STRIP_FILES - List of files in the source tree that
          will be stripped. Starting with CMake 2.6.0
          CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables
          stripping of all files (a list of files evaluates to TRUE in CMake,
          so this change is compatible).
 
     
 
          CPACK_SOURCE_GENERATOR - List of generators used for the source
          packages. As with CPACK_GENERATOR, if this is not specified then
          CPack will create a set of options (e.g., CPACK_SOURCE_ZIP)
          allowing users to select which packages will be generated.
 
     
 
          CPACK_SOURCE_OUTPUT_CONFIG_FILE - The name of the CPack
          configuration file for source installers that will be generated by
          the CPack module. Defaults to CPackSourceConfig.cmake.
 
     
 
          CPACK_SOURCE_IGNORE_FILES - Pattern of files in the source tree
          that won't be packaged when building a source package. This is a
          list of patterns, e.g., /CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*
 
     
 
      The following variables are specific to the graphical installers built
      on Windows using the Nullsoft Installation System.
 
          CPACK_PACKAGE_INSTALL_REGISTRY_KEY - Registry key used when
          installing this project.
 
     
 
          CPACK_NSIS_MUI_ICON - The icon file (.ico) for the generated
          install program.
 
     
 
          CPACK_NSIS_MUI_UNIICON - The icon file (.ico) for the generated
          uninstall program.
 
     
 
          CPACK_PACKAGE_ICON - A branding image that will be displayed inside
          the installer.
 
     
 
          CPACK_NSIS_EXTRA_INSTALL_COMMANDS - Extra NSIS commands that will
          be added to the install Section.
 
     
 
          CPACK_NSIS_EXTRA_UNINSTALL_COMMANDS - Extra NSIS commands that will
          be added to the uninstall Section.
 
     
 
          CPACK_NSIS_COMPRESSOR - The arguments that will be passed to the
          NSIS SetCompressor command.
 
     
 
          CPACK_NSIS_MODIFY_PATH - If this is set to "ON", then an extra page
          will appear in the installer that will allow the user to choose
          whether the program directory should be added to the system PATH
          variable.
 
     
 
          CPACK_NSIS_DISPLAY_NAME - The title displayed at the top of the
          installer.
 
     
 
          CPACK_NSIS_INSTALLED_ICON_NAME - A path to the executable that
          contains the installer icon.
 
     
 
          CPACK_NSIS_HELP_LINK - URL to a web site providing assistance in
          installing your application.
 
     
 
          CPACK_NSIS_URL_INFO_ABOUT - URL to a web site providing more
          information about your application.
 
     
 
          CPACK_NSIS_CONTACT - Contact information for questions and comments
          about the installation process.
 
     
 
          CPACK_NSIS_CREATE_ICONS_EXTRA - Additional NSIS commands for
          creating start menu shortcuts.
 
     
 
          CPACK_NSIS_DELETE_ICONS_EXTRA -Additional NSIS commands to
          uninstall start menu shortcuts.
 
     
 
      The following variable is specific to installers build on Mac OS X
      using PackageMaker:
 
          CPACK_OSX_PACKAGE_VERSION - The version of Mac OS X that the
          resulting PackageMaker archive should be compatible
          with. Different versions of Mac OS X support different
          features. For example, CPack can only build component-based
          installers for Mac OS X 10.4 or newer, and can only build
          installers that download component son-the-fly for Mac OS X 10.5
          or newer. If left blank, this value will be set to the minimum
          version of Mac OS X that supports the requested features. Set this
          variable to some value (e.g., 10.4) only if you want to guarantee
          that your installer will work on that version of Mac OS X, and
          don't mind missing extra features available in the installer
          shipping with later versions of Mac OS X.
 
     
 
      The following variables are for advanced uses of CPack:
 
          CPACK_CMAKE_GENERATOR - What CMake generator should be used if the
          project is CMake project. Defaults to the value of CMAKE_GENERATOR;
          few users will want to change this setting.
 
     
 
          CPACK_INSTALL_CMAKE_PROJECTS - List of four values that specify
          what project to install. The four values are: Build directory,
          Project Name, Project Component, Directory. If omitted, CPack will
          build an installer that installers everything.
 
     
 
          CPACK_SYSTEM_NAME - System name, defaults to the value of
          ${CMAKE_SYSTEM_NAME}.
 
     
 
          CPACK_PACKAGE_VERSION - Package full version, used internally. By
          default, this is built from CPACK_PACKAGE_VERSION_MAJOR,
          CPACK_PACKAGE_VERSION_MINOR, and CPACK_PACKAGE_VERSION_PATCH.
 
     
 
          CPACK_TOPLEVEL_TAG - Directory for the installed files.
 
     
 
          CPACK_INSTALL_COMMANDS - Extra commands to install components.
 
     
 
          CPACK_INSTALL_DIRECTORIES - Extra directories to install.
 
     
 
      Component-specific installation allows users to select specific sets
      of components to install during the install process.  Installation
      components are identified by the COMPONENT argument of CMake's INSTALL
      commands, and should be further described by the following CPack
      commands:
 
          cpack_add_component - Describes a CPack installation component
          named by the COMPONENT argument to a CMake INSTALL command.
 
     
 
            cpack_add_component(compname
                                [DISPLAY_NAME name]
                                [DESCRIPTION description]
                                [HIDDEN | REQUIRED | DISABLED ]
                                [GROUP group]
                                [DEPENDS comp1 comp2 ... ]
                                [INSTALL_TYPES type1 type2 ... ]
                                [DOWNLOADED]
                                [ARCHIVE_FILE filename])
 
     
 
          The cmake_add_component command describes an installation
          component, which the user can opt to install or remove as part of
          the graphical installation process. compname is the name of the
          component, as provided to the COMPONENT argument of one or more
          CMake INSTALL commands.
 
     
 
          DISPLAY_NAME is the displayed name of the component, used in
          graphical installers to display the component name. This value can
          be any string.
 
     
 
          DESCRIPTION is an extended description of the component, used in
          graphical installers to give the user additional information about
          the component. Descriptions can span multiple lines using "\n" as
          the line separator. Typically, these descriptions should be no
          more than a few lines long.
 
     
 
          HIDDEN indicates that this component will be hidden in the
          graphical installer, so that the user cannot directly change
          whether it is installed or not.
 
     
 
          REQUIRED indicates that this component is required, and therefore
          will always be installed. It will be visible in the graphical
          installer, but it cannot be unselected. (Typically, required
          components are shown greyed out).
 
     
 
          DISABLED indicates that this component should be disabled
          (unselected) by default. The user is free to select this component
          for installation, unless it is also HIDDEN.
 
     
 
          DEPENDS lists the components on which this component depends. If
          this component is selected, then each of the components listed
          must also be selected. The dependency information is encoded
          within the installer itself, so that users cannot install
          inconsitent sets of components.
 
     
 
          GROUP names the component group of which this component is a
          part. If not provided, the component will be a standalone
          component, not part of any component group. Component groups are
          described with the cpack_add_component_group command, detailed
          below.
 
     
 
          INSTALL_TYPES lists the installation types of which this component
          is a part. When one of these installations types is selected, this
          component will automatically be selected. Installation types are
          described with the cpack_add_install_type command, detailed below.
 
     
 
          DOWNLOADED indicates that this component should be downloaded
          on-the-fly by the installer, rather than packaged in with the
          installer itself. For more information, see the cpack_configure_downloads
          command.
 
     
 
          ARCHIVE_FILE provides a name for the archive file created by CPack
          to be used for downloaded components. If not supplied, CPack will
          create a file with some name based on CPACK_PACKAGE_FILE_NAME and
          the name of the component. See cpack_configure_downloads for more
          information.
 
     
 
          cpack_add_component_group - Describes a group of related CPack
          installation components.
 
     
 
            cpack_add_component_group(groupname
                                    [DISPLAY_NAME name]
                                    [DESCRIPTION description]
                                    [PARENT_GROUP parent]
                                    [EXPANDED]
                                    [BOLD_TITLE])
 
     
 
          The cpack_add_component_group describes a group of installation
          components, which will be placed together within the listing of
          options. Typically, component groups allow the user to
          select/deselect all of the components within a single group via a
          single group-level option. Use component groups to reduce the
          complexity of installers with many options. groupname is an
          arbitrary name used to identify the group in the GROUP argument of
          the cpack_add_component command, which is used to place a
          component in a group. The name of the group must not conflict with
          the name of any component.
 
     
 
          DISPLAY_NAME is the displayed name of the component group, used in
          graphical installers to display the component group name. This
          value can be any string.
 
     
 
          DESCRIPTION is an extended description of the component group,
          used in graphical installers to give the user additional
          information about the components within that group. Descriptions
          can span multiple lines using "\n" as the line
          separator. Typically, these descriptions should be no more than a
          few lines long.
 
     
 
          PARENT_GROUP, if supplied, names the parent group of this group.
          Parent groups are used to establish a hierarchy of groups,
          providing an arbitrary hierarchy of groups.
 
     
 
          EXPANDED indicates that, by default, the group should show up as
          "expanded", so that the user immediately sees all of the
          components within the group. Otherwise, the group will initially
          show up as a single entry.
 
     
 
          BOLD_TITLE indicates that the group title should appear in bold,
          to call the user's attention to the group.
 
     
 
          cpack_add_install_type - Add a new installation type containing a
          set of predefined component selections to the graphical installer.
                           
            cpack_add_install_type(typename
                                  [DISPLAY_NAME name]) 
 
     
 
          The cpack_add_install_type command identifies a set of preselected
          components that represents a common use case for an
          application. For example, a "Developer" install type might include
          an application along with its header and library files, while an
          "End user" install type might just include the application's
          executable. Each component identifies itself with one or more
          install types via the INSTALL_TYPES argument to
          cpack_add_component.
 
     
 
          DISPLAY_NAME is the displayed name of the install type, which will
          typically show up in a drop-down box within a graphical
          installer. This value can be any string.
 
     
 
          cpack_configure_downloads - Configure CPack to download selected
          components on-the-fly as part of the installation process.
 
     
 
            cpack_configure_downloads(site
                                      [UPLOAD_DIRECTORY dirname]
                                      [ALL]
                                      [ADD_REMOVE|NO_ADD_REMOVE])
 
     
 
          The cpack_configure_downloads command configures installation-time
          downloads of selected components. For each downloadable component,
          CPack will create an archive containing the contents of that
          component, which should be uploaded to the given site. When the
          user selects that component for installation, the installer will
          download and extract the component in place. This feature is
          useful for creating small installers that only download the
          requested components, saving bandwidth. Additionally, the
          installers are small enough that they will be installed as part of
          the normal installation process, and the "Change" button in
          Windows Add/Remove Programs control panel will allow one to add or
          remove parts of the application after the original
          installation. On Windows, the downloaded-components functionality
          requires the ZipDLL plug-in for NSIS, available at:
 
     
 
            http://nsis.sourceforge.net/ZipDLL_plug-in
 
     
 
          On Mac OS X, installers that download components on-the-fly can
          only be built and installed on system using Mac OS X 10.5 or
          later.
 
     
 
          The site argument is a URL where the archives for downloadable
          components will reside, e.g., http://www.cmake.org/files/2.6.1/installer/
          All of the archives produced by CPack should be uploaded to that location.
 
     
 
          UPLOAD_DIRECTORY is the local directory where CPack will create the
          various archives for each of the components. The contents of this
          directory should be uploaded to a location accessible by the URL given
          in the site argument. If omitted, CPack will use the directory CPackUploads
          inside the CMake binary directory to store the generated archives.
 
     
 
          The ALL flag indicates that all components be downloaded. Otherwise, only
          those components explicitly marked as DOWNLOADED or that have a specified
          ARCHIVE_FILE will be downloaded. Additionally, the ALL option implies
          ADD_REMOVE (unless NO_ADD_REMOVE is specified).
 
     
 
          ADD_REMOVE indicates that CPack should install a copy of the installer
          that can be called from Windows' Add/Remove Programs dialog (via the
          "Modify" button) to change the set of installed components. NO_ADD_REMOVE
          turns off this behavior. This option is ignored on Mac OS X.

  Dart
      Configure a project for testing with CTest or old Dart Tcl Client
 
      This file is the backwards-compatibility version of the CTest module.
      It supports using the old Dart 1 Tcl client for driving dashboard
      submissions as well as testing with CTest.  This module should be
      included in the CMakeLists.txt file at the top of a project.  Typical
      usage:
 
        INCLUDE(Dart)
        IF(BUILD_TESTING)
          # ... testing related CMake code ...
        ENDIF(BUILD_TESTING)
 
      The BUILD_TESTING option is created by the Dart module to determine
      whether testing support should be enabled.  The default is ON.
 
  Documentation
      DocumentationVTK.cmake
 
      This file provides support for the VTK documentation framework.  It
      relies on several tools (Doxygen, Perl, etc).
 
  FeatureSummary
      Macros for generating a summary of enabled/disabled features
 
     
 
      PRINT_ENABLED_FEATURES()
 
          Print a summary of all enabled features. By default all successfull
          FIND_PACKAGE() calls will appear here, except the ones which used the QUIET keyword.
          Additional features can be added by appending an entry to the global ENABLED_FEATURES
          property. If SET_FEATURE_INFO() is used for that feature, the output will be much
          more informative.
 
     
 
      PRINT_DISABLED_FEATURES()
 
          Same as PRINT_ENABLED_FEATURES(), but for disabled features. It can be extended
          the same way by adding to the global property DISABLED_FEATURES.
 
     
 
      SET_FEATURE_INFO(NAME DESCRIPTION [URL [COMMENT] ] )
 
          Use this macro to set up information about the named feature, which will
          then be displayed by PRINT_ENABLED/DISABLED_FEATURES().
          Example: SET_FEATURE_INFO(LibXml2 "XML processing library." "http://xmlsoft.org/")
 
     
 
 
  FindASPELL
      Try to find ASPELL
 
      Once done this will define
 
        ASPELL_FOUND - system has ASPELL
        ASPELL_INCLUDE_DIR - the ASPELL include directory
        ASPELL_LIBRARIES - The libraries needed to use ASPELL
        ASPELL_DEFINITIONS - Compiler switches required for using ASPELL
 
 
  FindAVIFile
      Locate AVIFILE library and include paths
 
      AVIFILE (http://avifile.sourceforge.net/)is a set of libraries for
      i386 machines to use various AVI codecs.  Support is limited beyond
      Linux.  Windows provides native AVI support, and so doesn't need this
      library.  This module defines
 
        AVIFILE_INCLUDE_DIR, where to find avifile.h , etc.
        AVIFILE_LIBRARIES, the libraries to link against
        AVIFILE_DEFINITIONS, definitions to use when compiling
        AVIFILE_FOUND, If false, don't try to use AVIFILE
 
 
  FindBLAS
      Find BLAS library
 
      This module finds an installed fortran library that implements the
      BLAS linear-algebra interface (see http://www.netlib.org/blas/).  The
      list of libraries searched for is taken from the autoconf macro file,
      acx_blas.m4 (distributed at
      http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).
 
      This module sets the following variables:
 
        BLAS_FOUND - set to true if a library implementing the BLAS interface
          is found
        BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
          and -L).
        BLAS_LIBRARIES - uncached list of libraries (using full path name) to
          link against to use BLAS
        BLAS95_LIBRARIES - uncached list of libraries (using full path name)
          to link against to use BLAS95 interface
        BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
          is found
        BLA_STATIC  if set on this determines what kind of linkage we do (static)
        BLA_VENDOR  if set checks only the specified vendor, if not set checks
            all the posibilities
        BLA_F95    if set on tries to find the f95 interfaces for BLAS/LAPACK
 
      ######### ## List of vendors (BLA_VENDOR) valid in this module #
      ATLAS, PhiPACK,CXML,DXML,SunPerf,SCSL,SGIMATH,IBMESSL,Intel10_32
      (intel mkl v10 32 bit),Intel10_64lp (intel mkl v10 64 bit,lp thread
      model, lp64 model), # Intel( older versions of mkl 32 and 64 bit),
      ACML,Apple, NAS, Generic C/CXX should be enabled to use Intel mkl
 
  FindBZip2
      Try to find BZip2
 
      Once done this will define
 
        BZIP2_FOUND - system has BZip2
        BZIP2_INCLUDE_DIR - the BZip2 include directory
        BZIP2_LIBRARIES - Link these to use BZip2
        BZIP2_DEFINITIONS - Compiler switches required for using BZip2
        BZIP2_NEED_PREFIX - this is set if the functions are prefixed with BZ2_
 
 
  FindBoost
      Try to find Boost include dirs and libraries
 
      Usage of this module as follows:
 
      == Using Header-Only libraries from within Boost: ==
 
          find_package( Boost 1.36.0 )
          if(Boost_FOUND)
            include_directories(${Boost_INCLUDE_DIRS})
            add_executable(foo foo.cc)
          endif()
 
     
 
     
 
      == Using actual libraries from within Boost: ==
 
          set(Boost_USE_STATIC_LIBS  ON)
          set(Boost_USE_MULTITHREADED ON)
          find_package( Boost 1.36.0 COMPONENTS date_time filesystem system ... )
 
     
 
          if(Boost_FOUND)
            include_directories(${Boost_INCLUDE_DIRS})
            add_executable(foo foo.cc)
            target_link_libraries(foo ${Boost_LIBRARIES})
          endif()
 
     
 
     
 
      The components list needs to contain actual names of boost libraries
      only, such as "date_time" for "libboost_date_time".  If you're using
      parts of Boost that contain header files only (e.g.  foreach) you do
      not need to specify COMPONENTS.
 
      You should provide a minimum version number that should be used.  If
      you provide this version number and specify the REQUIRED attribute,
      this module will fail if it can't find the specified or a later
      version.  If you specify a version number this is automatically put
      into the considered list of version numbers and thus doesn't need to
      be specified in the Boost_ADDITIONAL_VERSIONS variable (see below).
 
      NOTE for Visual Studio Users:
 
            Automatic linking is used on MSVC & Borland compilers by default when
            #including things in Boost.  It's important to note that setting
            Boost_USE_STATIC_LIBS to OFF is NOT enough to get you dynamic linking,
            should you need this feature.  Automatic linking typically uses static
            libraries with a few exceptions (Boost.Python is one).
 
     
 
            Please see the section below near Boost_LIB_DIAGNOSTIC_DEFINITIONS for
            more details.  Adding a TARGET_LINK_LIBRARIES() as shown in the example
            above appears to cause VS to link dynamically if Boost_USE_STATIC_LIBS
            gets set to OFF.  It is suggested you avoid automatic linking since it
            will make your application less portable.
 
     
 
      =========== The mess that is Boost_ADDITIONAL_VERSIONS (sorry?)
      ============
 
      OK, so the Boost_ADDITIONAL_VERSIONS variable can be used to specify a
      list of boost version numbers that should be taken into account when
      searching for Boost.  Unfortunately boost puts the version number into
      the actual filename for the libraries, so this variable will certainly
      be needed in the future when new Boost versions are released.
 
      Currently this module searches for the following version numbers:
      1.33, 1.33.0, 1.33.1, 1.34, 1.34.0, 1.34.1, 1.35, 1.35.0, 1.35.1,
      1.36, 1.36.0, 1.36.1, 1.37, 1.37.0, 1.38, 1.38.0
 
      NOTE: If you add a new major 1.x version in Boost_ADDITIONAL_VERSIONS
      you should add both 1.x and 1.x.0 as shown above.  Official Boost
      include directories omit the 3rd version number from include paths if
      it is 0 although not all binary Boost releases do so.
 
      SET(Boost_ADDITIONAL_VERSIONS "0.99" "0.99.0" "1.78" "1.78.0")
 
     
      ============================================================================
 
 
      Variables used by this module, they can change the default behaviour
      and need to be set before calling find_package:
 
        Boost_USE_MULTITHREADED      Can be set to OFF to use the non-multithreaded
                                      boost libraries.  If not specified, defaults
                                      to ON.
 
     
 
        Boost_USE_STATIC_LIBS        Can be set to ON to force the use of the static
                                      boost libraries. Defaults to OFF.
 
     
 
      Other Variables used by this module which you may want to set.
 
        Boost_ADDITIONAL_VERSIONS    A list of version numbers to use for searching
                                      the boost include directory.  Please see
                                      the documentation above regarding this
                                      annoying, but necessary variable :(
 
     
 
        Boost_DEBUG                  Set this to TRUE to enable debugging output
                                      of FindBoost.cmake if you are having problems.
                                      Please enable this before filing any bug
                                      reports.
 
     
 
        Boost_COMPILER                Set this to the compiler suffix used by Boost
                                      (e.g. "-gcc43") if FindBoods has problems finding
                                      the proper Boost installation
 
     
 
        These last three variables are available also as environment variables:
 
     
 
        BOOST_ROOT or BOOSTROOT      The preferred installation prefix for searching for
                                      Boost.  Set this if the module has problems finding
                                      the proper Boost installation.
 
     
 
        BOOST_INCLUDEDIR              Set this to the include directory of Boost, if the
                                      module has problems finding the proper Boost installation
 
     
 
        BOOST_LIBRARYDIR              Set this to the lib directory of Boost, if the
                                      module has problems finding the proper Boost installation
 
     
 
      Variables defined by this module:
 
        Boost_FOUND                          System has Boost, this means the include dir was
                                              found, as well as all the libraries specified in
                                              the COMPONENTS list.
 
     
 
        Boost_INCLUDE_DIRS                  Boost include directories: not cached
 
     
 
        Boost_INCLUDE_DIR                    This is almost the same as above, but this one is
                                              cached and may be modified by advanced users
 
     
 
        Boost_LIBRARIES                      Link these to use the Boost libraries that you
                                              specified: not cached

        Boost_VERSION                        The version number of the boost libraries that
                                              have been found, same as in version.hpp from Boost

        Boost_SUBMINOR_VERSION              subminor version number of boost
 
     
 
        Boost_LIB_DIAGNOSTIC_DEFINITIONS    [WIN32 Only] You can call
                                              add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINTIIONS})
                                              to have diagnostic information about Boost's
                                              automatic linking outputted during compilation time.
 
     
 
      For each component you list the following variables are set.
      ATTENTION: The component names need to be in lower case, just as the
      boost library names however the CMake variables use upper case for the
      component part.  So you'd get Boost_SERIALIZATION_FOUND for example.
 
        Boost_${COMPONENT}_FOUND            True IF the Boost library "component" was found.
        Boost_${COMPONENT}_LIBRARY          The absolute path of the Boost library "component".

        Boost_${COMPONENT}_LIBRARY_RELEASE  The absolute path of the release version of the
                                              Boost library "component"

        MPEG2_vo_LIBRARY, where to find the vo library.
 
 
  FindMPI
      Message Passing Interface (MPI) module.
 
     
 
      The Message Passing Interface (MPI) is a library used to write
      high-performance parallel applications that use message passing, and
      is typically deployed on a cluster.  MPI is a standard interface
      (defined by the MPI forum) for which many implementations are
      available.  All of these implementations have somewhat different
      compilation approaches (different include paths, libraries to link
      against, etc.), and this module tries to smooth out those differences.
 
      This module will set the following variables:
 
          MPI_FOUND                  TRUE if we have found MPI
          MPI_COMPILE_FLAGS          Compilation flags for MPI programs
          MPI_INCLUDE_PATH          Include path(s) for MPI header
          MPI_LINK_FLAGS            Linking flags for MPI programs
          MPI_LIBRARY                First MPI library to link against (cached)
          MPI_EXTRA_LIBRARY          Extra MPI libraries to link against (cached)
          MPI_LIBRARIES              All libraries to link MPI programs against
          MPIEXEC                    Executable for running MPI programs
          MPIEXEC_NUMPROC_FLAG      Flag to pass to MPIEXEC before giving it the
                                    number of processors to run on
          MPIEXEC_PREFLAGS          Flags to pass to MPIEXEC directly before the
                                    executable to run.
          MPIEXEC_POSTFLAGS          Flags to pass to MPIEXEC after all other flags.
 
     
 
      This module will attempt to auto-detect these settings, first by
      looking for a MPI compiler, which many MPI implementations provide as
      a pass-through to the native compiler to simplify the compilation of
      MPI programs.  The MPI compiler is stored in the cache variable
      MPI_COMPILER, and will attempt to look for commonly-named drivers
      mpic++, mpicxx, mpiCC, or mpicc.  If the compiler driver is found and
      recognized, it will be used to set all of the module variables.  To
      skip this auto-detection, set MPI_LIBRARY and MPI_INCLUDE_PATH in the
      CMake cache.
 
      If no compiler driver is found or the compiler driver is not
      recognized, this module will then search for common include paths and
      library names to try to detect MPI.
 
      If CMake initially finds a different MPI than was intended, and you
      want to use the MPI compiler auto-detection for a different MPI
      implementation, set MPI_COMPILER to the MPI compiler driver you want
      to use (e.g., mpicxx) and then set MPI_LIBRARY to the string
      MPI_LIBRARY-NOTFOUND.  When you re-configure, auto-detection of MPI
      will run again with the newly-specified MPI_COMPILER.
 
      When using MPIEXEC to execute MPI applications, you should typically
      use all of the MPIEXEC flags as follows:
 
          ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS ${MPIEXEC_PREFLAGS} EXECUTABLE
            ${MPIEXEC_POSTFLAGS} ARGS
 
      where PROCS is the number of processors on which to execute the
      program, EXECUTABLE is the MPI program, and ARGS are the arguments to
      pass to the MPI program.
 
  FindMatlab
      this module looks for Matlab
 
      Defines:

      OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX
 
  FindOpenMP
      Finds OpenMP support
 
      This module can be used to detect OpenMP support in a compiler.  If
      the compiler supports OpenMP, the flags required to compile with
      openmp support are set.
 
      The following variables are set:

  FindOpenSceneGraph
      Find OpenSceneGraph
 
      This module searches for the OpenSceneGraph core "osg" library as well
      as OpenThreads, and whatever additional COMPONENTS that you specify.
 
          See http://www.openscenegraph.org
 
     
 
      NOTE: If you would like to use this module in your CMAKE_MODULE_PATH
      instead of requiring CMake >= 2.6.3, you will also need to download
      FindOpenThreads.cmake, Findosg_functions.cmake, Findosg.cmake, as well
      as files for any Components you need to call (FindosgDB.cmake,
      FindosgUtil.cmake, etc.)

          OpenSceneGraph_DEBUG - Enable debugging output
 
     
 
          OpenSceneGraph_MARK_AS_ADVANCED - Mark cache variables as advanced
                                            automatically
 
     
 
      The following environment variables are also respected for finding the
      OSG and it's various components.  CMAKE_PREFIX_PATH can also be used
      for this (see find_library() CMake documentation).
 
          <MODULE>_DIR (where MODULE is of the form "OSGVOLUME" and there is a FindosgVolume.cmake file)

  FindOpenThreads
       
 
      OpenThreads is a C++ based threading library.  Its largest userbase
      seems to OpenSceneGraph so you might notice I accept OSGDIR as an
      environment path.  I consider this part of the Findosg* suite used to
      find OpenSceneGraph components.  Each component is separate and you
      must opt in to each module.
 
      Locate OpenThreads This module defines OPENTHREADS_LIBRARY
      OPENTHREADS_FOUND, if false, do not try to link to OpenThreads
      OPENTHREADS_INCLUDE_DIR, where to find the headers
 
      $OPENTHREADS_DIR is an environment variable that would correspond to

  FindPHP4
      Find PHP4
 
      This module finds if PHP4 is installed and determines where the
      include files and libraries are.  It also determines what the name of
      the library is.  This code sets the following variables:
 
        PHP4_INCLUDE_PATH      = path to where php.h can be found
        PHP4_EXECUTABLE        = full path to the php4 binary
 
     
 
 
  FindPNG
      Find the native PNG includes and library
 
     
 
      This module defines
 
        PNG_INCLUDE_DIR, where to find png.h, etc.
        PNG_LIBRARIES, the libraries to link against to use PNG.
        PNG_DEFINITIONS - You should ADD_DEFINITONS(${PNG_DEFINITIONS}) before compiling code that includes png library files.
        PNG_FOUND, If false, do not try to use PNG.
 
      also defined, but not for general use are
 
        PNG_LIBRARY, where to find the PNG library.
 
      None of the above will be defined unles zlib can be found.  PNG
      depends on Zlib
 
  FindPackageHandleStandardArgs
       
 
      FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME (DEFAULT_MSG|"Custom failure
      message") VAR1 ...  )
 
          This macro is intended to be used in FindXXX.cmake modules files.
          It handles the REQUIRED and QUIET argument to FIND_PACKAGE() and
          it also sets the <UPPERCASED_NAME>_FOUND variable.
          The package is found if all variables listed are TRUE.
          Example:
 
     
 
          FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2 DEFAULT_MSG LIBXML2_LIBRARIES LIBXML2_INCLUDE_DIR)
 
     
 
          LibXml2 is considered to be found, if both LIBXML2_LIBRARIES and
          LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to TRUE.
          If it is not found and REQUIRED was used, it fails with FATAL_ERROR,
          independent whether QUIET was used or not.
          If it is found, the location is reported using the VAR1 argument, so
          here a message "Found LibXml2: /usr/lib/libxml2.so" will be printed out.
          If the second argument is DEFAULT_MSG, the message in the failure case will
          be "Could NOT find LibXml2", if you don't like this message you can specify
          your own custom failure message there.
 
 
  FindPackageMessage
       
 
      FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")
 
      This macro is intended to be used in FindXXX.cmake modules files.  It
      will print a message once for each unique find result.  This is useful
      for telling the user where a package was found.  The first argument
      specifies the name (XXX) of the package.  The second argument
      specifies the message to display.  The third argument lists details
      about the find result so that if they change the message will be
      displayed again.  The macro also obeys the QUIET argument to the
      find_package command.
 
      Example:
 
        IF(X11_FOUND)
          FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
            "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
        ELSE(X11_FOUND)
          ...
        ENDIF(X11_FOUND)
 
 
  FindPerl
      Find perl
 
      this module looks for Perl
 
        PERL_EXECUTABLE - the full path to perl
        PERL_FOUND      - If false, don't attempt to use perl.
 
 
  FindPerlLibs
      Find Perl libraries
 
      This module finds if PERL is installed and determines where the
      include files and libraries are.  It also determines what the name of
      the library is.  This code sets the following variables:
 
        PERL_INCLUDE_PATH = path to where perl.h is found
        PERL_EXECUTABLE  = full path to the perl binary
 
     
 
 
  FindPhysFS
       
 
      Locate PhysFS library This module defines PHYSFS_LIBRARY, the name of
      the library to link against PHYSFS_FOUND, if false, do not try to link
      to PHYSFS PHYSFS_INCLUDE_DIR, where to find physfs.h
 
      $PHYSFSDIR is an environment variable that would correspond to the
      ./configure --prefix=$PHYSFSDIR used in building PHYSFS.
 
      Created by Eric Wing.
 
  FindPike
      Find Pike
 
      This module finds if PIKE is installed and determines where the
      include files and libraries are.  It also determines what the name of
      the library is.  This code sets the following variables:
 
        PIKE_INCLUDE_PATH      = path to where program.h is found
        PIKE_EXECUTABLE        = full path to the pike binary
 
     
 
 
  FindPkgConfig
      a pkg-config module for CMake
 
     
 
      Usage:
 
          pkg_check_modules(<PREFIX> [REQUIRED] <MODULE> [<MODULE>]*)
            checks for all the given modules
 
     
 
          pkg_search_module(<PREFIX> [REQUIRED] <MODULE> [<MODULE>]*)
            checks for given modules and uses the first working one
 
     
 
      When the 'REQUIRED' argument was set, macros will fail with an error
      when module(s) could not be found
 
      It sets the following variables:
 
          PKG_CONFIG_FOUND        ... true if pkg-config works on the system
          PKG_CONFIG_EXECUTABLE    ... pathname of the pkg-config program
          <PREFIX>_FOUND          ... set to 1 if module(s) exist
 
     
 
      For the following variables two sets of values exist; first one is the
      common one and has the given PREFIX.  The second set contains flags
      which are given out when pkgconfig was called with the '--static'
      option.
 
          <XPREFIX>_LIBRARIES      ... only the libraries (w/o the '-l')
          <XPREFIX>_LIBRARY_DIRS  ... the paths of the libraries (w/o the '-L')
          <XPREFIX>_LDFLAGS        ... all required linker flags
          <XPREFIX>_LDFLAGS_OTHER  ... all other linker flags
          <XPREFIX>_INCLUDE_DIRS  ... the '-I' preprocessor flags (w/o the '-I')
          <XPREFIX>_CFLAGS        ... all required cflags
          <XPREFIX>_CFLAGS_OTHER  ... the other compiler flags
 
     
 
          <XPREFIX> = <PREFIX>        for common case
          <XPREFIX> = <PREFIX>_STATIC for static linking
 
     
 
      There are some special variables whose prefix depends on the count of
      given modules.  When there is only one module, <PREFIX> stays
      unchanged.  When there are multiple modules, the prefix will be
      changed to <PREFIX>_<MODNAME>:
 
          <XPREFIX>_VERSION    ... version of the module
          <XPREFIX>_PREFIX    ... prefix-directory of the module
          <XPREFIX>_INCLUDEDIR ... include-dir of the module
          <XPREFIX>_LIBDIR    ... lib-dir of the module
 
     
 
          <XPREFIX> = <PREFIX>  when |MODULES| == 1, else
          <XPREFIX> = <PREFIX>_<MODNAME>
 
     
 
      A <MODULE> parameter can have the following formats:
 
          {MODNAME}            ... matches any version
          {MODNAME}>={VERSION} ... at least version <VERSION> is required
          {MODNAME}={VERSION}  ... exactly version <VERSION> is required
          {MODNAME}<={VERSION} ... modules must not be newer than <VERSION>
 
     
 
      Examples
 
          pkg_check_modules (GLIB2  glib-2.0)
 
     
 
          pkg_check_modules (GLIB2  glib-2.0>=2.10)
            requires at least version 2.10 of glib2 and defines e.g.
              GLIB2_VERSION=2.10.3
 
     
 
          pkg_check_modules (FOO    glib-2.0>=2.10 gtk+-2.0)
            requires both glib2 and gtk2, and defines e.g.
              FOO_glib-2.0_VERSION=2.10.3
              FOO_gtk+-2.0_VERSION=2.8.20
 
     
 
          pkg_check_modules (XRENDER REQUIRED xrender)
            defines e.g.:
              XRENDER_LIBRARIES=Xrender;X11
              XRENDER_STATIC_LIBRARIES=Xrender;X11;pthread;Xau;Xdmcp
 
     
 
          pkg_search_module (BAR    libxml-2.0 libxml2 libxml>=2)
 
 
  FindProducer
       
 
      Though Producer isn't directly part of OpenSceneGraph, its primary
      user is OSG so I consider this part of the Findosg* suite used to find
      OpenSceneGraph components.  You'll notice that I accept OSGDIR as an
      environment path.
 
      Each component is separate and you must opt in to each module.  You
      must also opt into OpenGL (and OpenThreads?) as these modules won't do
      it for you.  This is to allow you control over your own system piece
      by piece in case you need to opt out of certain components or change
      the Find behavior for a particular module (perhaps because the default
      FindOpenGL.cmake module doesn't work with your system as an example).
      If you want to use a more convenient module that includes everything,
      use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake
      modules.
 
      Locate Producer This module defines PRODUCER_LIBRARY PRODUCER_FOUND,
      if false, do not try to link to Producer PRODUCER_INCLUDE_DIR, where
      to find the headers
 
      $PRODUCER_DIR is an environment variable that would correspond to the
      ./configure --prefix=$PRODUCER_DIR used in building osg.

  FindPythonInterp
      Find python interpreter
 
      This module finds if Python interpreter is installed and determines
      where the executables are.  This code sets the following variables:
 
        PYTHONINTERP_FOUND - Was the Python executable found
        PYTHON_EXECUTABLE  - path to the Python interpreter
 
     
 
 
  FindPythonLibs
      Find python libraries
 
      This module finds if Python is installed and determines where the
      include files and libraries are.  It also determines what the name of
      the library is.  This code sets the following variables:
 
        PYTHONLIBS_FOUND    = have the Python libs been found
        PYTHON_LIBRARIES    = path to the python library
        PYTHON_INCLUDE_PATH  = path to where Python.h is found
        PYTHON_DEBUG_LIBRARIES = path to the debug library
 
     
 
 
  FindQt
      Searches for all installed versions of QT.
 
      This should only be used if your project can work with multiple
      versions of QT.  If not, you should just directly use FindQt4 or
      FindQt3.  If multiple versions of QT are found on the machine, then
      The user must set the option DESIRED_QT_VERSION to the version they
      want to use.  If only one version of qt is found on the machine, then
      the DESIRED_QT_VERSION is set to that version and the matching FindQt3
      or FindQt4 module is included.  Once the user sets DESIRED_QT_VERSION,
      then the FindQt3 or FindQt4 module is included.
 
        QT_REQUIRED if this is set to TRUE then if CMake can
                    not find QT4 or QT3 an error is raised
                    and a message is sent to the user.
 
     
 
        DESIRED_QT_VERSION OPTION is created
        QT4_INSTALLED is set to TRUE if qt4 is found.
        QT3_INSTALLED is set to TRUE if qt3 is found.
 
 
  FindQt3
      Locate Qt include paths and libraries
 
      This module defines:
 
        QT_INCLUDE_DIR - where to find qt.h, etc.
        QT_LIBRARIES  - the libraries to link against to use Qt.
        QT_DEFINITIONS - definitions to use when
                          compiling code that uses Qt.
        QT_FOUND      - If false, don't try to use Qt.
 
     
 
      If you need the multithreaded version of Qt, set QT_MT_REQUIRED to
      TRUE
 
      Also defined, but not for general use are:
 
        QT_MOC_EXECUTABLE, where to find the moc tool.
        QT_UIC_EXECUTABLE, where to find the uic tool.
        QT_QT_LIBRARY, where to find the Qt library.
        QT_QTMAIN_LIBRARY, where to find the qtmain
          library. This is only required by Qt3 on Windows.
 
 
  FindQt4
      Find QT 4
 
      This module can be used to find Qt4.  The most important issue is that
      the Qt4 qmake is available via the system path.  This qmake is then
      used to detect basically everything else.  This module defines a
      number of key variables and macros.  First is QT_USE_FILE which is the
      path to a CMake file that can be included to compile Qt 4 applications
      and libraries.  By default, the QtCore and QtGui libraries are loaded.
      This behavior can be changed by setting one or more of the following
      variables to true before doing INCLUDE(${QT_USE_FILE}):
 
                          QT_DONT_USE_QTCORE
                          QT_DONT_USE_QTGUI

      The file pointed to by QT_USE_FILE will set up your compile
      environment by adding include directories, preprocessor defines, and
      populate a QT_LIBRARIES variable containing all the Qt libraries and
      their dependencies.  Add the QT_LIBRARIES variable to your
      TARGET_LINK_LIBRARIES.
 
      Typical usage could be something like:
 
          FIND_PACKAGE(Qt4)
          SET(QT_USE_QTXML 1)
          INCLUDE(${QT_USE_FILE})
          ADD_EXECUTABLE(myexe main.cpp)
          TARGET_LINK_LIBRARIES(myexe ${QT_LIBRARIES})
 
     
 
     
 
      There are also some files that need processing by some Qt tools such
      as moc and uic.  Listed below are macros that may be used to process
      those files.
 
       
        macro QT4_WRAP_CPP(outfiles inputfile ... OPTIONS ...)
              create moc code from a list of files containing Qt class with
              the Q_OBJECT declaration.  Per-direcotry preprocessor definitions
              are also added.  Options may be given to moc, such as those found
              when executing "moc -help". 
 
     
 
        macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...)
              create code from a list of Qt designer ui files.
              Options may be given to uic, such as those found
              when executing "uic -help"
 
     
 
        macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...)
              create code from a list of Qt resource files.
              Options may be given to rcc, such as those found
              when executing "rcc -help"
 
     
 
        macro QT4_GENERATE_MOC(inputfile outputfile )
              creates a rule to run moc on infile and create outfile.
              Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g.
              because you need a custom filename for the moc file or something similar.
 
     
 
        macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... )
              This macro is still experimental.
              It can be used to have moc automatically handled.
              So if you have the files foo.h and foo.cpp, and in foo.h a
              a class uses the Q_OBJECT macro, moc has to run on it. If you don't
              want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
              #include "foo.moc"
              in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will the
              scan all listed files at cmake-time for such included moc files and if it finds
              them cause a rule to be generated to run moc at build time on the
              accompanying header file foo.h.
              If a source file has the SKIP_AUTOMOC property set it will be ignored by this macro.
 
     
 
        macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename)
              create a the interface header and implementation files with the
              given basename from the given interface xml file and add it to
              the list of sources
 
     
 
        macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... )
              create the interface header and implementation files
              for all listed interface xml files
              the name will be automatically determined from the name of the xml file
 
     
 
        macro QT4_ADD_DBUS_ADAPTOR(outfiles xmlfile parentheader parentclassname [basename] )
              create a dbus adaptor (header and implementation file) from the xml file
              describing the interface, and add it to the list of sources. The adaptor
              forwards the calls to a parent class, defined in parentheader and named
              parentclassname. The name of the generated files will be
              <basename>adaptor.{cpp,h} where basename is the basename of the xml file.
 
     
 
        macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] )
              generate the xml interface file from the given header.
              If the optional argument interfacename is omitted, the name of the
              interface file is constructed from the basename of the header with
              the suffix .xml appended.
 
     
 
        macro QT4_CREATE_TRANSLATION( qm_files directories ... sources ...
                                      ts_files ... OPTIONS ...)
              out: qm_files
              in:  directories sources ts_files
              options: flags to pass to lupdate, such as -extensions to specify
              extensions for a directory scan.
              generates commands to create .ts (vie lupdate) and .qm
              (via lrelease) - files from directories and/or sources. The ts files are
              created and/or updated in the source tree (unless given with full paths).
              The qm files are generated in the build tree.
              Updating the translations can be done by adding the qm_files
              to the source list of your library/executable, so they are
              always updated, or by adding a custom target to control when
              they get updated/generated.
 
     
 
        macro QT4_ADD_TRANSLATION( qm_files ts_files ... )
              out: qm_files
              in:  ts_files
              generates commands to create .qm from .ts - files. The generated
              filenames can be found in qm_files. The ts_files
              must exists and are not updated in any way.

  FindQuickTime
       
 
      Locate QuickTime This module defines QUICKTIME_LIBRARY
      QUICKTIME_FOUND, if false, do not try to link to gdal
      QUICKTIME_INCLUDE_DIR, where to find the headers
 
      $QUICKTIME_DIR is an environment variable that would correspond to the
      ./configure --prefix=$QUICKTIME_DIR
 
      Created by Eric Wing.
 
  FindRTI
      Try to find M&S HLA RTI libraries
 
      This module finds if any HLA RTI is installed and locates the standard
      RTI include files and libraries.
 
      RTI is a simulation infrastructure standartized by IEEE and SISO.  It
      has a well defined C++ API that assures that simulation applications
      are independent on a particular RTI implementation.
      http://en.wikipedia.org/wiki/Run-Time_Infrastructure_(simulation)
 
      This code sets the following variables:
 
        RTI_INCLUDE_DIR = the directory where RTI includes file are found
        RTI_LIBRARIES = The libraries to link against to use RTI
        RTI_DEFINITIONS = -DRTI_USES_STD_FSTREAM
        RTI_FOUND = Set to FALSE if any HLA RTI was not found
 
     
 
      Report problems to <certi-devel@nongnu.org>
 
  FindRuby
      Find Ruby
 
      This module finds if Ruby is installed and determines where the
      include files and libraries are.  It also determines what the name of
      the library is.  This code sets the following variables:
 
        RUBY_INCLUDE_PATH = path to where ruby.h can be found
        RUBY_EXECUTABLE  = full path to the ruby binary
        RUBY_LIBRARY      = full path to the ruby library
 
 
  FindSDL
       
 
      Locate SDL library This module defines SDL_LIBRARY, the name of the
      library to link against SDL_FOUND, if false, do not try to link to SDL
      SDL_INCLUDE_DIR, where to find SDL.h
 
      This module responds to the the flag: SDL_BUILDING_LIBRARY If this is
      defined, then no SDL_main will be linked in because only applications
      need main().  Otherwise, it is assumed you are building an application
      and this module will attempt to locate and set the the proper link
      flags as part of the returned SDL_LIBRARY variable.
 
      Don't forget to include SDLmain.h and SDLmain.m your project for the
      OS X framework based version.  (Other versions link to -lSDLmain which
      this module will try to find on your behalf.) Also for OS X, this
      module will automatically add the -framework Cocoa on your behalf.
 
     
 
      Additional Note: If you see an empty SDL_LIBRARY_TEMP in your
      configuration and no SDL_LIBRARY, it means CMake did not find your SDL
      library (SDL.dll, libsdl.so, SDL.framework, etc).  Set
      SDL_LIBRARY_TEMP to point to your SDL library, and configure again.
      Similarly, if you see an empty SDLMAIN_LIBRARY, you should set this
      value as appropriate.  These values are used to generate the final
      SDL_LIBRARY variable, but when these values are unset, SDL_LIBRARY
      does not get created.
 
     
 
      $SDLDIR is an environment variable that would correspond to the
      ./configure --prefix=$SDLDIR used in building SDL.  l.e.galup 9-20-02
 
      Modified by Eric Wing.  Added code to assist with automated building
      by using environmental variables and providing a more
      controlled/consistent search behavior.  Added new modifications to
      recognize OS X frameworks and additional Unix paths (FreeBSD, etc).
      Also corrected the header search path to follow "proper" SDL
      guidelines.  Added a search for SDLmain which is needed by some
      platforms.  Added a search for threads which is needed by some
      platforms.  Added needed compile switches for MinGW.
 
      On OSX, this will prefer the Framework version (if found) over others.
      People will have to manually change the cache values of SDL_LIBRARY to
      override this selection or set the CMake environment
      CMAKE_INCLUDE_PATH to modify the search paths.
 
      Note that the header path has changed from SDL/SDL.h to just SDL.h
      This needed to change because "proper" SDL convention is #include
      "SDL.h", not <SDL/SDL.h>.  This is done for portability reasons
      because not all systems place things in SDL/ (see FreeBSD).
 
  FindSDL_image
       
 
      Locate SDL_image library This module defines SDLIMAGE_LIBRARY, the

  FindTCL
      TK_INTERNAL_PATH was removed.
 
      This module finds if Tcl is installed and determines where the include
      files and libraries are.  It also determines what the name of the
      library is.  This code sets the following variables:
 
        TCL_FOUND              = Tcl was found
        TK_FOUND              = Tk was found
        TCLTK_FOUND            = Tcl and Tk were found
        TCL_LIBRARY            = path to Tcl library (tcl tcl80)
        TCL_INCLUDE_PATH      = path to where tcl.h can be found
        TCL_TCLSH              = path to tclsh binary (tcl tcl80)
        TK_LIBRARY            = path to Tk library (tk tk80 etc)
        TK_INCLUDE_PATH        = path to where tk.h can be found
        TK_WISH                = full path to the wish executable
 
     
 
      In an effort to remove some clutter and clear up some issues for
      people who are not necessarily Tcl/Tk gurus/developpers, some
      variables were moved or removed.  Changes compared to CMake 2.4 are:
 
          => they were only useful for people writing Tcl/Tk extensions.
          => these libs are not packaged by default with Tcl/Tk distributions.
            Even when Tcl/Tk is built from source, several flavors of debug libs
            are created and there is no real reason to pick a single one
            specifically (say, amongst tcl84g, tcl84gs, or tcl84sgx).
            Let's leave that choice to the user by allowing him to assign
            TCL_LIBRARY to any Tcl library, debug or not.
          => this ended up being only a Win32 variable, and there is a lot of
            confusion regarding the location of this file in an installed Tcl/Tk
            tree anyway (see 8.5 for example). If you need the internal path at
            this point it is safer you ask directly where the *source* tree is
            and dig from there.

      Find the native TIFF includes and library This module defines
 
        TIFF_INCLUDE_DIR, where to find tiff.h, etc.

  FindTclsh
      Find tclsh
 
      This module finds if TCL is installed and determines where the include

      library is.  This code sets the following variables:
 
        TCLSH_FOUND = TRUE if tclsh has been found
        TCL_TCLSH = the path to the tclsh executable
 
      In cygwin, look for the cygwin version first.  Don't look for it later
      to avoid finding the cygwin version on a Win32 build.

      The following cache entries must be set by the user to locate VTK:
 
        VTK_DIR  - The directory containing VTKConfig.cmake. 
                    This is either the root of the build tree,
                    or the lib/vtk directory.  This is the
                    only cache entry.
 
      The following variables are set for backward compatibility and should
      not be used in new code:

  Findosg
       
 
     
 
      NOTE: It is highly recommended that you use the new
      FindOpenSceneGraph.cmake introduced in CMake 2.6.3 and not use this
      Find module directly.
 
      This is part of the Findosg* suite used to find OpenSceneGraph
      components.  Each component is separate and you must opt in to each
      module.  You must also opt into OpenGL and OpenThreads (and Producer
      if needed) as these modules won't do it for you.  This is to allow you
      control over your own system piece by piece in case you need to opt
      out of certain components or change the Find behavior for a particular
      module (perhaps because the default FindOpenGL.cmake module doesn't
      work with your system as an example).  If you want to use a more
      convenient module that includes everything, use the
      FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

  FindosgSim
       
 
      This is part of the Findosg* suite used to find OpenSceneGraph
      components.  Each component is separate and you must opt in to each
      module.  You must also opt into OpenGL and OpenThreads (and Producer
      if needed) as these modules won't do it for you.  This is to allow you
      control over your own system piece by piece in case you need to opt
      out of certain components or change the Find behavior for a particular
      module (perhaps because the default FindOpenGL.cmake module doesn't
      work with your system as an example).  If you want to use a more

  Findosg_functions
       
 
     
 
      This CMake file contains two macros to assist with searching for OSG
      libraries and nodekits.
 
 
  FindwxWidgets
      Find a wxWidgets (a.k.a., wxWindows) installation.
 
      This module finds if wxWidgets is installed and selects a default
      configuration to use.  wxWidgets is a modular library.  To specify the
      modules that you will use, you need to name them as components to the
      package:
 
      FIND_PACKAGE(wxWidgets COMPONENTS base core ...)
 
      There are two search branches: a windows style and a unix style.  For
      windows, the following variables are searched for and set to defaults
      in case of multiple choices.  Change them if the defaults are not
      desired (i.e., these are the only variables you should change to
      select a configuration):
 
        wxWidgets_ROOT_DIR      - Base wxWidgets directory
                                  (e.g., C:/wxWidgets-2.6.3).
        wxWidgets_LIB_DIR      - Path to wxWidgets libraries
                                  (e.g., C:/wxWidgets-2.6.3/lib/vc_lib).
        wxWidgets_CONFIGURATION - Configuration to use
                                  (e.g., msw, mswd, mswu, mswunivud, etc.)
 
     
 
      For unix style it uses the wx-config utility.  You can select between
      debug/release, unicode/ansi, universal/non-universal, and
      static/shared in the QtDialog or ccmake interfaces by turning ON/OFF
      the following variables:
 
        wxWidgets_USE_DEBUG
        wxWidgets_USE_UNICODE
        wxWidgets_USE_UNIVERSAL
        wxWidgets_USE_STATIC
       
 
      The following are set after the configuration is done for both windows
      and unix style:
 
        wxWidgets_FOUND            - Set to TRUE if wxWidgets was found.
        wxWidgets_INCLUDE_DIRS    - Include directories for WIN32
                                      i.e., where to find "wx/wx.h" and
                                      "wx/setup.h"; possibly empty for unices.
        wxWidgets_LIBRARIES        - Path to the wxWidgets libraries.
        wxWidgets_LIBRARY_DIRS    - compile time link dirs, useful for
                                      rpath on UNIX. Typically an empty string
                                      in WIN32 environment.
        wxWidgets_DEFINITIONS      - Contains defines required to compile/link
                                      against WX, e.g. -DWXUSINGDLL
        wxWidgets_CXX_FLAGS        - Include dirs and ompiler flags for
                                      unices, empty on WIN32. Esentially
                                      "`wx-config --cxxflags`".
        wxWidgets_USE_FILE        - Convenience include file.
 
     
 
      Sample usage:
 
          FIND_PACKAGE(wxWidgets COMPONENTS base core gl net)
          IF(wxWidgets_FOUND)
            INCLUDE(${wxWidgets_USE_FILE})
            # and for each of your dependant executable/library targets:
            TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})
          ENDIF(wxWidgets_FOUND)
 
     
 
      If wxWidgets is required (i.e., not an optional part):
 
          FIND_PACKAGE(wxWidgets REQUIRED base core gl net)
          INCLUDE(${wxWidgets_USE_FILE})
          # and for each of your dependant executable/library targets:
          TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})
 
 
  FindwxWindows
      Find wxWindows (wxWidgets) installation
 
      This module finds if wxWindows/wxWidgets is installed and determines
      where the include files and libraries are.  It also determines what
      the name of the library is.  Please note this file is DEPRECATED and
      replaced by FindwxWidgets.cmake.  This code sets the following
      variables:
 
        WXWINDOWS_FOUND    = system has WxWindows
        WXWINDOWS_LIBRARIES = path to the wxWindows libraries
                              on Unix/Linux with additional
                              linker flags from
                              "wx-config --libs"
        CMAKE_WXWINDOWS_CXX_FLAGS  = Compiler flags for wxWindows,
                                      essentially "`wx-config --cxxflags`"
                                      on Linux
        WXWINDOWS_INCLUDE_DIR      = where to find "wx/wx.h" and "wx/setup.h"
        WXWINDOWS_LINK_DIRECTORIES = link directories, useful for rpath on
                                      Unix
        WXWINDOWS_DEFINITIONS      = extra defines
 
     
 
      OPTIONS If you need OpenGL support please
 
        SET(WXWINDOWS_USE_GL 1)
 
      in your CMakeLists.txt *before* you include this file.
 
        HAVE_ISYSTEM      - true required to replace -I by -isystem on g++
 
     
 
      For convenience include Use_wxWindows.cmake in your project's
      CMakeLists.txt using INCLUDE(Use_wxWindows).
 
      USAGE
 
        SET(WXWINDOWS_USE_GL 1)
        FIND_PACKAGE(wxWindows)
 
     
 
      NOTES wxWidgets 2.6.x is supported for monolithic builds e.g.
      compiled in wx/build/msw dir as:
 
        nmake -f makefile.vc BUILD=debug SHARED=0 USE_OPENGL=1 MONOLITHIC=1

  FortranCInterface
       
 
      FortranCInterface.cmake
 
      This file defines the function create_fortran_c_interface.  this
      function is used to create a configured header file that contains a
      mapping from C to a Fortran function using the correct name mangling
      scheme as defined by the current fortran compiler.
 
      The function tages a list of functions and the name of a header file
      to configure.
 
      This file also defines some helper functions that are used to detect
      the fortran name mangling scheme used by the current Fortran compiler.
 
        test_fortran_mangling - test a single fortran mangling
        discover_fortran_mangling - loop over all combos of fortran
          name mangling and call test_fortran_mangling until one of them
          works.
        discover_fortran_module_mangling - try different types of
        fortran modle name mangling to find one that works
 
     
 
     
 
     
 
      this function tests a single fortran mangling.  CODE - test code to
      try should define a subroutine called "sub" PREFIX - string to put in
      front of sub POSTFIX - string to put after sub ISUPPER - if TRUE then
      sub will be called as SUB DOC - string used in status checking Fortran
      ${DOC} linkage SUB - the name of the SUB to call RESULT place to store
      result TRUE if this linkage works, FALSE
 
              if not.
 
     
 
 
  GetPrerequisites
       
 
      GetPrerequisites.cmake
 
      This script provides functions to list the .dll, .dylib or .so files
      that an executable or shared library file depends on.  (Its
      prerequisites.)
 
      It uses various tools to obtain the list of required shared library
      files:
 
          dumpbin (Windows)
          ldd (Linux/Unix)
          otool (Mac OSX)
 
     
 
      The following functions are provided by this script:
 
          gp_append_unique
          gp_file_type
          is_file_executable
          gp_item_default_embedded_path
            (projects can override with gp_item_default_embedded_path_override)
          gp_resolve_item
            (projects can override with gp_resolve_item_override)
          get_prerequisites
          list_prerequisites
          list_prerequisites_by_glob
 
     
 
      Requires CMake 2.6 or greater because it uses function, break, return
      and PARENT_SCOPE.

  InstallRequiredSystemLibraries
       
 
      By including this file, all files in the
      CMAKE_INSTALL_DEBUG_LIBRARIES, will be installed with INSTALL_PROGRAMS
      into /bin for WIN32 and /lib for non-win32.  If
      CMAKE_SKIP_INSTALL_RULES is set to TRUE before including this file,
      then the INSTALL command is not called.  The use can use the variable
      CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS to use a custom install command and
      install them into any directory they want.  If it is the MSVC
      compiler, then the microsoft run time libraries will be found add
      automatically added to the CMAKE_INSTALL_DEBUG_LIBRARIES, and
      installed.  If CMAKE_INSTALL_DEBUG_LIBRARIES is set and it is the MSVC
      compiler, then the debug libraries are installed when available.  If
      CMAKE_INSTALL_MFC_LIBRARIES is set then the MFC run time libraries are
      installed as well as the CRT run time libraries.

  SquishTestScript
       
 
     
 
      This script launches a GUI test using Squish.  You should not call the
      script directly; instead, you should acces it via the SQUISH_ADD_TEST
      macro that is defined in FindSquish.cmake.
 
      This script starts the Squish server, launches the test on the client,
      and finally stops the squish server.  If any of these steps fail
      (including if the tests do not pass) then a fatal error is raised.

      It contains the following variables: ECOS_DEFINITIONS
      ECOSCONFIG_EXECUTABLE ECOS_CONFIG_FILE - defaults to ecos.ecc, if your
      eCos configuration file has a different name, adjust this variable for
      internal use only:
 
        ECOS_ADD_TARGET_LIB
 
 
  UsePkgConfig
      obsolete pkg-config module for CMake
 
     
 
      Defines the following macros:
 
      PKGCONFIG(package includedir libdir linkflags cflags)
 
      Calling PKGCONFIG will fill the desired information into the 4 given
      arguments, e.g.  PKGCONFIG(libart-2.0 LIBART_INCLUDE_DIR
      LIBART_LINK_DIR LIBART_LINK_FLAGS LIBART_CFLAGS) if pkg-config was NOT

      the respective information
 
 
  UseQt4
      Use Module for QT4
 
      Sets up C and C++ to use Qt 4.  It is assumed that FindQt.cmake has
      already been loaded.  See FindQt.cmake for information on how to load
      Qt 4 into your CMake project.
 
  UseSWIG
      SWIG module for CMake
 
      Defines the following macros:
 
          SWIG_ADD_MODULE(name language [ files ])
            - Define swig module with given name and specified language
          SWIG_LINK_LIBRARIES(name [ libraries ])
            - Link libraries to swig module
 
      All other macros are for internal use only.  To get the actual name of
      the swig module, use: ${SWIG_MODULE_name_REAL_NAME}.  Set Source files
      properties such as CPLUSPLUS and SWIG_FLAGS to specify special
      behavior of SWIG.  Also global CMAKE_SWIG_FLAGS can be used to add
      special flags to all swig calls.  Another special variable is
      CMAKE_SWIG_OUTDIR, it allows one to specify where to write all the
      swig generated module (swig -outdir option) The name-specific variable
      SWIG_MODULE_<name>_EXTRA_DEPS may be used to specify extra
      dependencies for the generated modules.

Policies
 
  CMP0000
      A minimum required CMake version must be specified.
 
      CMake requires that projects specify the version of CMake to which
      they have been written.  This policy has been put in place so users
      trying to build the project may be told when they need to update their
      CMake.  Specifying a version also helps the project build with CMake
      versions newer than that specified.  Use the cmake_minimum_required
      command at the top of your main CMakeLists.txt file:
 
        cmake_minimum_required(VERSION <major>.<minor>)
 
      where "<major>.<minor>" is the version of CMake you want to support
      (such as "2.6").  The command will ensure that at least the given
      version of CMake is running and help newer versions be compatible with
      the project.  See documentation of cmake_minimum_required for details.
 
      Note that the command invocation must appear in the CMakeLists.txt
      file itself; a call in an included file is not sufficient.  However,
      the cmake_policy command may be called to set policy CMP0000 to OLD or
      NEW behavior explicitly.  The OLD behavior is to silently ignore the
      missing invocation.  The NEW behavior is to issue an error instead of
      a warning.  An included file may set CMP0000 explicitly to affect how
      this policy is enforced for the main CMakeLists.txt file.
 
      This policy was introduced in CMake version 2.6.0.
 
  CMP0001
      CMAKE_BACKWARDS_COMPATIBILITY should no longer be used.
 
      The OLD behavior is to check CMAKE_BACKWARDS_COMPATIBILITY and present
      it to the user.  The NEW behavior is to ignore
      CMAKE_BACKWARDS_COMPATIBILITY completely.
 
      In CMake 2.4 and below the variable CMAKE_BACKWARDS_COMPATIBILITY was
      used to request compatibility with earlier versions of CMake.  In
      CMake 2.6 and above all compatibility issues are handled by policies
      and the cmake_policy command.  However, CMake must still check
      CMAKE_BACKWARDS_COMPATIBILITY for projects written for CMake 2.4 and
      below.
 
      This policy was introduced in CMake version 2.6.0.  CMake version 2.6
      warns when the policy is not set and uses OLD behavior.  Use the
      cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0002
      Logical target names must be globally unique.
 
      Targets names created with add_executable, add_library, or
      add_custom_target are logical build target names.  Logical target
      names must be globally unique because:
 
        - Unique names may be referenced unambiguously both in CMake
          code and on make tool command lines.
        - Logical names are used by Xcode and VS IDE generators
          to produce meaningful project names for the targets.
 
      The logical name of executable and library targets does not have to
      correspond to the physical file names built.  Consider using the
      OUTPUT_NAME target property to create two targets with the same
      physical name while keeping logical names distinct.  Custom targets
      must simply have globally unique names (unless one uses the global
      property ALLOW_DUPLICATE_CUSTOM_TARGETS with a Makefiles generator).
 
      This policy was introduced in CMake version 2.6.0.  CMake version 2.6
      warns when the policy is not set and uses OLD behavior.  Use the
      cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0003
      Libraries linked via full path no longer produce linker search paths.
 
      This policy affects how libraries whose full paths are NOT known are
      found at link time, but was created due to a change in how CMake deals
      with libraries whose full paths are known.  Consider the code
 
        target_link_libraries(myexe /path/to/libA.so)
 
      CMake 2.4 and below implemented linking to libraries whose full paths
      are known by splitting them on the link line into separate components
      consisting of the linker search path and the library name.  The
      example code might have produced something like
 
        ... -L/path/to -lA ...
 
      in order to link to library A.  An analysis was performed to order
      multiple link directories such that the linker would find library A in
      the desired location, but there are cases in which this does not work.
      CMake versions 2.6 and above use the more reliable approach of passing
      the full path to libraries directly to the linker in most cases.  The
      example code now produces something like
 
        ... /path/to/libA.so ....
 
      Unfortunately this change can break code like
 
        target_link_libraries(myexe /path/to/libA.so B)
 
      where "B" is meant to find "/path/to/libB.so".  This code is wrong
      because the user is asking the linker to find library B but has not
      provided a linker search path (which may be added with the
      link_directories command).  However, with the old linking
      implementation the code would work accidentally because the linker
      search path added for library A allowed library B to be found.
 
      In order to support projects depending on linker search paths added by
      linking to libraries with known full paths, the OLD behavior for this
      policy will add the linker search paths even though they are not
      needed for their own libraries.  When this policy is set to OLD, CMake
      will produce a link line such as
 
        ... -L/path/to /path/to/libA.so -lB ...
 
      which will allow library B to be found as it was previously.  When
      this policy is set to NEW, CMake will produce a link line such as
 
        ... /path/to/libA.so -lB ...
 
      which more accurately matches what the project specified.
 
      The setting for this policy used when generating the link line is that
      in effect when the target is created by an add_executable or
      add_library command.  For the example described above, the code
 
        cmake_policy(SET CMP0003 OLD) # or cmake_policy(VERSION 2.4)
        add_executable(myexe myexe.c)
        target_link_libraries(myexe /path/to/libA.so B)
 
      will work and suppress the warning for this policy.  It may also be
      updated to work with the corrected linking approach:
 
        cmake_policy(SET CMP0003 NEW) # or cmake_policy(VERSION 2.6)
        link_directories(/path/to) # needed to find library B
        add_executable(myexe myexe.c)
        target_link_libraries(myexe /path/to/libA.so B)
 
      Even better, library B may be specified with a full path:
 
        add_executable(myexe myexe.c)
        target_link_libraries(myexe /path/to/libA.so /path/to/libB.so)
 
      When all items on the link line have known paths CMake does not check
      this policy so it has no effect.
 
      Note that the warning for this policy will be issued for at most one
      target.  This avoids flooding users with messages for every target
      when setting the policy once will probably fix all targets.
 
      This policy was introduced in CMake version 2.6.0.  CMake version 2.6
      warns when the policy is not set and uses OLD behavior.  Use the
      cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0004
      Libraries linked may not have leading or trailing whitespace.
 
      CMake versions 2.4 and below silently removed leading and trailing
      whitespace from libraries linked with code like
 
        target_link_libraries(myexe " A ")
 
      This could lead to subtle errors in user projects.
 
      The OLD behavior for this policy is to silently remove leading and
      trailing whitespace.  The NEW behavior for this policy is to diagnose
      the existence of such whitespace as an error.  The setting for this
      policy used when checking the library names is that in effect when the
      target is created by an add_executable or add_library command.
 
      This policy was introduced in CMake version 2.6.0.  CMake version 2.6
      warns when the policy is not set and uses OLD behavior.  Use the
      cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0005
      Preprocessor definition values are now escaped automatically.
 
      This policy determines whether or not CMake should generate escaped
      preprocessor definition values added via add_definitions.  CMake
      versions 2.4 and below assumed that only trivial values would be given
      for macros in add_definitions calls.  It did not attempt to escape
      non-trivial values such as string literals in generated build rules.
      CMake versions 2.6 and above support escaping of most values, but
      cannot assume the user has not added escapes already in an attempt to
      work around limitations in earlier versions.
 
      The OLD behavior for this policy is to place definition values given
      to add_definitions directly in the generated build rules without
      attempting to escape anything.  The NEW behavior for this policy is to
      generate correct escapes for all native build tools automatically.
      See documentation of the COMPILE_DEFINITIONS target property for
      limitations of the escaping implementation.
 
      This policy was introduced in CMake version 2.6.0.  CMake version 2.6
      warns when the policy is not set and uses OLD behavior.  Use the
      cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0006
      Installing MACOSX_BUNDLE targets requires a BUNDLE DESTINATION.
 
      This policy determines whether the install(TARGETS) command must be
      given a BUNDLE DESTINATION when asked to install a target with the
      MACOSX_BUNDLE property set.  CMake 2.4 and below did not distinguish
      application bundles from normal executables when installing targets.
      CMake 2.6 provides a BUNDLE option to the install(TARGETS) command
      that specifies rules specific to application bundles on the Mac.
      Projects should use this option when installing a target with the
      MACOSX_BUNDLE property set.
 
      The OLD behavior for this policy is to fall back to the RUNTIME
      DESTINATION if a BUNDLE DESTINATION is not given.  The NEW behavior
      for this policy is to produce an error if a bundle target is installed
      without a BUNDLE DESTINATION.
 
      This policy was introduced in CMake version 2.6.0.  CMake version 2.6
      warns when the policy is not set and uses OLD behavior.  Use the
      cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0007
      list command no longer ignores empty elements.
 
      This policy determines whether the list command will ignore empty
      elements in the list.  CMake 2.4 and below list commands ignored all
      empty elements in the list.  For example, a;b;;c would have length 3
      and not 4.  The OLD behavior for this policy is to ignore empty list
      elements.  The NEW behavior for this policy is to correctly count
      empty elements in a list.
 
      This policy was introduced in CMake version 2.6.0.  CMake version 2.6
      warns when the policy is not set and uses OLD behavior.  Use the
      cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0008
      Libraries linked by full-path must have a valid library file name.
 
      In CMake 2.4 and below it is possible to write code like
 
        target_link_libraries(myexe /full/path/to/somelib)
 
      where "somelib" is supposed to be a valid library file name such as
      "libsomelib.a" or "somelib.lib".  For Makefile generators this
      produces an error at build time because the dependency on the full
      path cannot be found.  For VS IDE and Xcode generators this used to
      work by accident because CMake would always split off the library
      directory and ask the linker to search for the library by name
      (-lsomelib or somelib.lib).  Despite the failure with Makefiles, some
      projects have code like this and build only with VS and/or Xcode.
      This version of CMake prefers to pass the full path directly to the
      native build tool, which will fail in this case because it does not
      name a valid library file.
 
      This policy determines what to do with full paths that do not appear
      to name a valid library file.  The OLD behavior for this policy is to
      split the library name from the path and ask the linker to search for
      it.  The NEW behavior for this policy is to trust the given path and
      pass it directly to the native build tool unchanged.
 
      This policy was introduced in CMake version 2.6.1.  CMake version 2.6
      warns when the policy is not set and uses OLD behavior.  Use the
      cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0009
      FILE GLOB_RECURSE calls should not follow symlinks by default.
 
      In CMake 2.6.1 and below, FILE GLOB_RECURSE calls would follow through
      symlinks, sometimes coming up with unexpectedly large result sets
      because of symlinks to top level directories that contain hundreds of
      thousands of files.
 
      This policy determines whether or not to follow symlinks encountered
      during a FILE GLOB_RECURSE call.  The OLD behavior for this policy is
      to follow the symlinks.  The NEW behavior for this policy is not to
      follow the symlinks by default, but only if FOLLOW_SYMLINKS is given
      as an additional argument to the FILE command.
 
      This policy was introduced in CMake version 2.6.2.  CMake version 2.6
      warns when the policy is not set and uses OLD behavior.  Use the
      cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0010
      Bad variable reference syntax is an error.
 
      In CMake 2.6.2 and below, incorrect variable reference syntax such as
      a missing close-brace ("${FOO") was reported but did not stop
      processing of CMake code.  This policy determines whether a bad
      variable reference is an error.  The OLD behavior for this policy is
      to warn about the error, leave the string untouched, and continue.
      The NEW behavior for this policy is to report an error.
 
      This policy was introduced in CMake version 2.6.3.  CMake version 2.6
      warns when the policy is not set and uses OLD behavior.  Use the
      cmake_policy command to set it to OLD or NEW explicitly.
 
  CMP0011
      Included scripts do automatic cmake_policy PUSH and POP.
 
      In CMake 2.6.2 and below, CMake Policy settings in scripts loaded by
      the include() and find_package() commands would affect the includer.
      Explicit invocations of cmake_policy(PUSH) and cmake_policy(POP) were
      required to isolate policy changes and protect the includer.  While
      some scripts intend to affect the policies of their includer, most do
      not.  In CMake 2.6.3 and above, include() and find_package() by
      default PUSH and POP an entry on the policy stack around an included
      script, but provide a NO_POLICY_SCOPE option to disable it.  This
      policy determines whether or not to imply NO_POLICY_SCOPE for
      compatibility.  The OLD behavior for this policy is to imply
      NO_POLICY_SCOPE for include() and find_package() commands.  The NEW
      behavior for this policy is to allow the commands to do their default
      cmake_policy PUSH and POP.
 
      This policy was introduced in CMake version 2.6.3.  CMake version 2.6
      warns when the policy is not set and uses OLD behavior.  Use the
      cmake_policy command to set it to OLD or NEW explicitly.
 
------------------------------------------------------------------------------
Variables
 
------------------------------------------------------------------------------
Variables That Change Behavior
 
  BUILD_SHARED_LIBS
      Global flag to cause add_library to create shared libraries if on.
 
      If present and true, this will cause all libraries to be built shared
      unless the library was explicitly added as a static library.  This
      variable is often added to projects as an OPTION so that each user of
      a project can decide if they want to build the project using shared or
      static libraries.
 
  CMAKE_BACKWARDS_COMPATIBILITY
      Version of cmake required to build project
 
      From the point of view of backwards compatibility, this specifies what
      version of CMake should be supported.  By default this value is the
      version number of CMake that you are running.  You can set this to an
      older version of CMake to support deprecated commands of CMake in
      projects that were written to use older versions of CMake.  This can
      be set by the user or set at the beginning of a CMakeLists file.
 
  CMAKE_BUILD_TYPE
      Specifies the build type for make based generators.
 
      This specifies what build type will be built in this tree.  Possible
      values are empty, Debug, Release, RelWithDebInfo and MinSizeRel.  This
      variable is only supported for make based generators.  If this
      variable is supported, then CMake will also provide initial values for
      the variables with the name
      CMAKE_C_FLAGS_[Debug|Release|RelWithDebInfo|MinSizeRel].  For example,
      if CMAKE_BUILD_TYPE is Debug, then CMAKE_C_FLAGS_DEBUG will be added
      to the CMAKE_C_FLAGS.
 
  CMAKE_COLOR_MAKEFILE
      Enables color output when using the Makefile generator.
 
      When enabled, the generated Makefiles will produce colored output.
      Default is ON.
 
  CMAKE_CONFIGURATION_TYPES
      Specifies the available build types.
 
      This specifies what build types will be available such as Debug,
      Release, RelWithDebInfo etc.  This has reasonable defaults on most
      platforms.  But can be extended to provide other build types.  See
      also CMAKE_BUILD_TYPE.
 
  CMAKE_FIND_LIBRARY_PREFIXES
      Prefixes to prepend when looking for libraries.
 
      This specifies what prefixes to add to library names when the
      find_library command looks for libraries.  On UNIX systems this is
      typically lib, meaning that when trying to find the foo library it
      will look for libfoo.
 
  CMAKE_FIND_LIBRARY_SUFFIXES
      Suffixes to append when looking for libraries.
 
      This specifies what suffixes to add to library names when the
      find_library command looks for libraries.  On Windows systems this is
      typically .lib and .dll, meaning that when trying to find the foo
      library it will look for foo.dll etc.
 
  CMAKE_INCLUDE_PATH
      Path used for searching by FIND_FILE() and FIND_PATH().
 
      Specifies a path which will be used both by FIND_FILE() and
      FIND_PATH().  Both commands will check each of the contained
      directories for the existence of the file which is currently searched.
      By default it is empty, it is intended to be set by the project.  See
      also CMAKE_SYSTEM_INCLUDE_PATH, CMAKE_PREFIX_PATH.
 
  CMAKE_INSTALL_PREFIX
      Install directory used by install.
 
      If "make install" is invoked or INSTALL is built, this directory is
      pre-pended onto all install directories.  This variable defaults to
      /usr/local on UNIX and c:/Program Files on Windows.
 
  CMAKE_LIBRARY_PATH
      Path used for searching by FIND_LIBRARY().
 
      Specifies a path which will be used by FIND_LIBRARY().  FIND_LIBRARY()
      will check each of the contained directories for the existence of the
      library which is currently searched.  By default it is empty, it is
      intended to be set by the project.  See also
      CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_PREFIX_PATH.
 
  CMAKE_MFC_FLAG
      Tell cmake to use MFC for an executable or dll.
 
      This can be set in a CMakeLists.txt file and will enable MFC in the
      application.  It should be set to 1 for static the static MFC library,
      and 2 for the shared MFC library.  This is used in visual studio 6 and
      7 project files.  The CMakeSetup dialog uses MFC and the
      CMakeLists.txt looks like this:
 
      ADD_DEFINITIONS(-D_AFXDLL)
 
      set(CMAKE_MFC_FLAG 2)
 
      add_executable(CMakeSetup WIN32 ${SRCS})
 
 
  CMAKE_MODULE_PATH
      Path to look for cmake modules to load.
 
      Specifies a path to override the default seach path for CMake modules.
      For example include commands will look in this path first for modules
      to include.
 
  CMAKE_NOT_USING_CONFIG_FLAGS
      Skip _BUILD_TYPE flags if true.
 
      This is an internal flag used by the generators in CMake to tell CMake
      to skip the _BUILD_TYPE flags.
 
  CMAKE_PREFIX_PATH
      Path used for searching by FIND_XXX(), with appropriate suffixes
      added.
 
      Specifies a path which will be used by the FIND_XXX() commands.  It
      contains the "base" directories, the FIND_XXX() commands append
      appropriate subdirectories to the base directories.  So FIND_PROGRAM()
      adds /bin to each of the directories in the path, FIND_LIBRARY()
      appends /lib to each of the directories, and FIND_PATH() and
      FIND_FILE() append /include .  By default it is empty, it is intended
      to be set by the project.  See also CMAKE_SYSTEM_PREFIX_PATH,
      CMAKE_INCLUDE_PATH, CMAKE_LIBRARY_PATH, CMAKE_PROGRAM_PATH.
 
  CMAKE_PROGRAM_PATH
      Path used for searching by FIND_PROGRAM().
 
      Specifies a path which will be used by FIND_PROGRAM().  FIND_PROGRAM()
      will check each of the contained directories for the existence of the
      program which is currently searched.  By default it is empty, it is
      intended to be set by the project.  See also
      CMAKE_SYSTEM_PROGRAM_PATH, CMAKE_PREFIX_PATH.
 
  CMAKE_SYSTEM_INCLUDE_PATH
      Path used for searching by FIND_FILE() and FIND_PATH().
 
      Specifies a path which will be used both by FIND_FILE() and
      FIND_PATH().  Both commands will check each of the contained
      directories for the existence of the file which is currently searched.
      By default it contains the standard directories for the current
      system.  It is NOT intended to be modified by the project, use
      CMAKE_INCLUDE_PATH for this.  See also CMAKE_SYSTEM_PREFIX_PATH.
 
  CMAKE_SYSTEM_LIBRARY_PATH
      Path used for searching by FIND_LIBRARY().
 
      Specifies a path which will be used by FIND_LIBRARY().  FIND_LIBRARY()
      will check each of the contained directories for the existence of the
      library which is currently searched.  By default it contains the
      standard directories for the current system.  It is NOT intended to be
      modified by the project, use CMAKE_SYSTEM_LIBRARY_PATH for this.  See
      also CMAKE_SYSTEM_PREFIX_PATH.
 
  CMAKE_SYSTEM_PREFIX_PATH
      Path used for searching by FIND_XXX(), with appropriate suffixes
      added.
 
      Specifies a path which will be used by the FIND_XXX() commands.  It
      contains the "base" directories, the FIND_XXX() commands append
      appropriate subdirectories to the base directories.  So FIND_PROGRAM()
      adds /bin to each of the directories in the path, FIND_LIBRARY()
      appends /lib to each of the directories, and FIND_PATH() and
      FIND_FILE() append /include .  By default this contains the standard
      directories for the current system.  It is NOT intended to be modified
      by the project, use CMAKE_PREFIX_PATH for this.  See also
      CMAKE_SYSTEM_INCLUDE_PATH, CMAKE_SYSTEM_LIBRARY_PATH,
      CMAKE_SYSTEM_PROGRAM_PATH.
 
  CMAKE_SYSTEM_PROGRAM_PATH
      Path used for searching by FIND_PROGRAM().
 
      Specifies a path which will be used by FIND_PROGRAM().  FIND_PROGRAM()
      will check each of the contained directories for the existence of the
      program which is currently searched.  By default it contains the
      standard directories for the current system.  It is NOT intended to be
      modified by the project, use CMAKE_PROGRAM_PATH for this.  See also
      CMAKE_SYSTEM_PREFIX_PATH.
 
  CMAKE_USER_MAKE_RULES_OVERRIDE
      Specify a file that can change the build rule variables.
 
      If this variable is set, it should to point to a CMakeLists.txt file
      that will be read in by CMake after all the system settings have been
      set, but before they have been used.  This would allow you to override
      any variables that need to be changed for some special project.
 
------------------------------------------------------------------------------
Variables That Describe the System
 
  APPLE
      True if running on Mac OSX.
 
      Set to true on Mac OSX.
 
  BORLAND
      True of the borland compiler is being used.
 
      This is set to true if the Borland compiler is being used.
 
  CMAKE_CL_64
      Using the 64 bit compiler from Microsoft
 
      Set to true when using the 64 bit cl compiler from Microsoft.
 
  CMAKE_COMPILER_2005
      Using the Visual Studio 2005 compiler from Microsoft
 
      Set to true when using the Visual Studio 2005 compiler from Microsoft.
 
  CMAKE_HOST_APPLE
      True for Apple OSXoperating systems.
 
      Set to true when the host system is Apple OSX.
 
  CMAKE_HOST_SYSTEM
      Name of system cmake is being run on.
 
      The same as CMAKE_SYSTEM but for the host system instead of the target
      system when cross compiling.
 
  CMAKE_HOST_SYSTEM_NAME
      Name of the OS CMake is running on.
 
      The same as CMAKE_SYSTEM_NAME but for the host system instead of the
      target system when cross compiling.
 
  CMAKE_HOST_SYSTEM_PROCESSOR
      The name of the CPU CMake is running on.
 
      The same as CMAKE_SYSTEM_PROCESSOR but for the host system instead of
      the target system when cross compiling.
 
  CMAKE_HOST_SYSTEM_VERSION
      OS version CMake is running on.
 
      The same as CMAKE_SYSTEM_VERSION but for the host system instead of
      the target system when cross compiling.
 
  CMAKE_HOST_UNIX
      True for UNIX and UNIX like operating systems.
 
      Set to true when the host system is UNIX or UNIX like (i.e.  APPLE and
      CYGWIN).
 
  CMAKE_HOST_WIN32
      True on windows systems, including win64.
 
      Set to true when the host system is Windows and on cygwin.
 
  CMAKE_OBJECT_PATH_MAX
      Maximum object file full-path length allowed by native build tools.
 
      CMake computes for every source file an object file name that is
      unique to the source file and deterministic with respect to the full
      path to the source file.  This allows multiple source files in a
      target to share the same name if they lie in different directories
      without rebuilding when one is added or removed.  However, it can
      produce long full paths in a few cases, so CMake shortens the path
      using a hashing scheme when the full path to an object file exceeds a
      limit.  CMake has a built-in limit for each platform that is
      sufficient for common tools, but some native tools may have a lower
      limit.  This variable may be set to specify the limit explicitly.  The
      value must be an integer no less than 128.
 
  CMAKE_SYSTEM
      Name of system cmake is compiling for.
 
      This variable is the composite of CMAKE_SYSTEM_NAMEand
      CMAKE_SYSTEM_VERSION, like this
      ${CMAKE_SYSTEM_NAME}-${CMAKE_SYSTEM_VERSION}.  If CMAKE_SYSTEM_VERSION
      is not set, then CMAKE_SYSTEM is the same as CMAKE_SYSTEM_NAME.
 
  CMAKE_SYSTEM_NAME
      Name of the OS CMake is building for.
 
      This is the name of the operating system on which CMake is targeting.
      On systems that have the uname command, this variable is set to the
      output of uname -s.  Linux, Windows, and Darwin for Mac OSX are the
      values found on the big three operating systems.
 
  CMAKE_SYSTEM_PROCESSOR
      The name of the CPU CMake is building for.
 
      On systems that support uname, this variable is set to the output of
      uname -p, on windows it is set to the value of the environment
      variable PROCESSOR_ARCHITECTURE
 
  CMAKE_SYSTEM_VERSION
      OS version CMake is building for.
 
      A numeric version string for the system, on systems that support
      uname, this variable is set to the output of uname -r.  On other
      systems this is set to major-minor version numbers.

      any variables that need to be changed for some language.
 
------------------------------------------------------------------------------
Variables that Control the Build
 
  CMAKE_<CONFIG>_POSTFIX
      Default filename postfix for libraries under configuration <CONFIG>.
 
      When a non-executable target is created its <CONFIG>_POSTFIX target
      property is initialized with the value of this variable if it is set.
 
  CMAKE_ARCHIVE_OUTPUT_DIRECTORY
      Where to put all the ARCHIVE targets when built.
 
      This variable is used to initialize the ARCHIVE_OUTPUT_DIRECTORY
      property on all the targets.  See that target property for additional
      information.
 
  CMAKE_BUILD_WITH_INSTALL_RPATH
      Use the install path for the RPATH
 
      Normally CMake uses the build tree for the RPATH when building
      executables etc on systems that use RPATH.  When the software is
      installed the executables etc are relinked by CMake to have the
      install RPATH.  If this variable is set to true then the software is
      always built with the install path for the RPATH and does not need to
      be relinked when installed.
 
  CMAKE_DEBUG_POSTFIX
      See variable CMAKE_<CONFIG>_POSTFIX.
 
      This variable is a special case of the more-general
      CMAKE_<CONFIG>_POSTFIX variable for the DEBUG configuration.
 
  CMAKE_EXE_LINKER_FLAGS
      Linker flags used to create executables.
 
      Flags used by the linker when creating an executable.
 
  CMAKE_EXE_LINKER_FLAGS_[CMAKE_BUILD_TYPE]
      Flag used when linking an executable.
 
      Same as CMAKE_C_FLAGS_* but used by the linker when creating
      executables.
 
  CMAKE_Fortran_MODULE_DIRECTORY
      Fortran module output directory.
 
      This variable is used to initialize the Fortran_MODULE_DIRECTORY
      property on all the targets.  See that target property for additional
      information.
 
  CMAKE_INSTALL_NAME_DIR
      Mac OSX directory name for installed targets.
 
      CMAKE_INSTALL_NAME_DIR is used to initialize the INSTALL_NAME_DIR
      property on all targets.  See that target property for more
      information.
 
  CMAKE_INSTALL_RPATH
      The rpath to use for installed targets.
 
      A semicolon-separated list specifying the rpath to use in installed
      targets (for platforms that support it).  This is used to initialize
      the target property INSTALL_RPATH for all targets.
 
  CMAKE_INSTALL_RPATH_USE_LINK_PATH
      Add paths to linker search and installed rpath.
 
      CMAKE_INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true
      will append directories in the linker search path and outside the
      project to the INSTALL_RPATH.  This is used to initialize the target
      property INSTALL_RPATH_USE_LINK_PATH for all targets.
 
  CMAKE_LIBRARY_OUTPUT_DIRECTORY
      Where to put all the LIBRARY targets when built.
 
      This variable is used to initialize the LIBRARY_OUTPUT_DIRECTORY
      property on all the targets.  See that target property for additional
      information.
 
  CMAKE_LIBRARY_PATH_FLAG
      The flag used to add a library search path to a compiler.
 
      The flag used to specify a library directory to the compiler.  On most
      compilers this is "-L".
 
  CMAKE_LINK_DEF_FILE_FLAG 
      Linker flag used to specify a .def file for dll creation.
 
      The flag used to add a .def file when creating a dll on Windows, this
      is only defined on Windows.
 
  CMAKE_LINK_LIBRARY_FILE_FLAG
      Flag used to link a library specified by a path to its file.
 
      The flag used before a library file path is given to the linker.  This
      is needed only on very few platforms.
 
  CMAKE_LINK_LIBRARY_FLAG
      Flag used to link a library into an executable.
 
      The flag used to specify a library to link to an executable.  On most
      compilers this is "-l".
 
  CMAKE_RUNTIME_OUTPUT_DIRECTORY
      Where to put all the RUNTIME targets when built.
 
      This variable is used to initialize the RUNTIME_OUTPUT_DIRECTORY
      property on all the targets.  See that target property for additional
      information.
 
  CMAKE_SKIP_BUILD_RPATH
      Do not include RPATHs in the build tree.
 
      Normally CMake uses the build tree for the RPATH when building
      executables etc on systems that use RPATH.  When the software is
      installed the executables etc are relinked by CMake to have the
      install RPATH.  If this variable is set to true then the software is
      always built with no RPATH.
 
  CMAKE_USE_RELATIVE_PATHS
      Use relative paths (May not work!).
 
      If this is set to TRUE, then the CMake will use relative paths between
      the source and binary tree.  This option does not work for more
      complicated projects, and relative paths are used when possible.  In
      general, it is not possible to move CMake generated makefiles to a
      different location regardless of the value of this variable.
 
  EXECUTABLE_OUTPUT_PATH
      Old executable location variable.
 
      This variable should no longer be used as of CMake 2.6.  Use the
      RUNTIME_OUTPUT_DIRECTORY target property instead.  It will override
      this variable if it is set.
 
      If set, this is the directory where all executables built during the
      build process will be placed.
 
  LIBRARY_OUTPUT_PATH
      Old library location variable.
 
      This variable should no longer be used as of CMake 2.6.  Use the
      ARCHIVE_OUTPUT_DIRECTORY, LIBRARY_OUTPUT_DIRECTORY, and
      RUNTIME_OUTPUT_DIRECTORY target properties instead.  They will
      override this variable if they are set.
 
      If set, this is the directory where all the libraries built during the
      build process will be placed.
 
------------------------------------------------------------------------------
Variables that Provide Information
 
variables defined by cmake, that give information about the project, and
cmake
 
  CMAKE_AR
      Name of archiving tool for static libraries.
 
      This specifies name of the program that creates archive or static
      libraries.
 
  CMAKE_BINARY_DIR
      The path to the top level of the build tree.
 
      This is the full path to the top level of the current CMake build
      tree.  For an in-source build, this would be the same as
      CMAKE_SOURCE_DIR.
 
  CMAKE_BUILD_TOOL
      Tool used for the acutal build process.
 
      This variable is set to the program that will be needed to build the
      output of CMake.  If the generator selected was Visual Studio 6, the
      CMAKE_MAKE_PROGRAM will be set to msdev, for Unix makefiles it will be
      set to make or gmake, and for Visual Studio 7 it set to devenv.  For
      Nmake Makefiles the value is nmake.  This can be useful for adding
      special flags and commands based on the final build environment.
 
  CMAKE_CACHEFILE_DIR
      The directory with the CMakeCache.txt file.
 
      This is the full path to the directory that has the CMakeCache.txt
      file in it.  This is the same as CMAKE_BINARY_DIR.
 
  CMAKE_CACHE_MAJOR_VERSION
      Major version of CMake used to create the CMakeCache.txt file
 
      This is stores the major version of CMake used to write a CMake cache
      file.  It is only different when a different version of CMake is run
      on a previously created cache file.
 
  CMAKE_CACHE_MINOR_VERSION
      Minor version of CMake used to create the CMakeCache.txt file
 
      This is stores the minor version of CMake used to write a CMake cache
      file.  It is only different when a different version of CMake is run
      on a previously created cache file.
 
  CMAKE_CACHE_RELEASE_VERSION
      Release version of CMake used to create the CMakeCache.txt file
 
      This is stores the release version of CMake used to write a CMake
      cache file.  It is only different when a different version of CMake is
      run on a previously created cache file.
 
  CMAKE_CFG_INTDIR
      Build time configuration directory for project.
 
      This is a variable that is used to provide developers access to the
      intermediate directory used by Visual Studio IDE projects.  For
      example, if building Debug all executables and libraries end up in a
      Debug directory.  On UNIX systems this variable is set to ".".
      However, with Visual Studio this variable is set to $(IntDir).
      $(IntDir) is expanded by the IDE only.  So this variable should only
      be used in custom commands that will be run during the build process.
      This variable should not be used directly in a CMake command.  CMake
      has no way of knowing if Debug or Release will be picked by the IDE
      for a build type.  If a program needs to know the directory it was
      built in, it can use CMAKE_INTDIR.  CMAKE_INTDIR is a C/C++
      preprocessor macro that is defined on the command line of the
      compiler.  If it has a value, it will be the intermediate directory
      used to build the file.  This way an executable or a library can find
      files that are located in the build directory.
 
  CMAKE_COMMAND
      The full path to the cmake executable.
 
      This is the full path to the CMake executable cmake which is useful
      from custom commands that want to use the cmake -E option for portable
      system commands.  (e.g.  /usr/local/bin/cmake
 
  CMAKE_CROSSCOMPILING
      Is CMake currently cross compiling.
 
      This variable will be set to true by CMake if CMake is cross
      compiling.  Specifically if the build platform is different from the
      target platform.
 
  CMAKE_CTEST_COMMAND
      Full path to ctest command installed with cmake.
 
      This is the full path to the CTest executable ctest which is useful
      from custom commands that want to use the cmake -E option for portable
      system commands.
 
  CMAKE_CURRENT_BINARY_DIR
      The path to the binary directory currently being processed.
 
      This the full path to the build directory that is currently being
      processed by cmake.  Each directory added by add_subdirectory will
      create a binary directory in the build tree, and as it is being
      processed this variable will be set.  For in-source builds this is the
      current source directory being processed.
 
  CMAKE_CURRENT_LIST_FILE
      Full path to the listfile currently being processed.
 
      As CMake processes the listfiles in your project this variable will
      always be set to the one currently being processed.  See also

      path is modified to look for 64 bit libraries first.
 
  CMAKE_SKIP_RPATH
      If true, do not add run time path information.
 
      If this is set to TRUE, then the rpath information is not added to
      compiled executables.  The defaultis to add rpath information if the
      platform supports it.This allows for easy running from the build tree.
 
  CMAKE_SOURCE_DIR
      The path to the top level of the source tree.
