cpack version 2.8.10
------------------------------------------------------------------------------
Name
 
  cpack - Packaging driver provided by CMake.
 
------------------------------------------------------------------------------
Usage
 
  cpack -G <generator> [options]
 
------------------------------------------------------------------------------
Description
 
The "cpack" executable is the CMake packaging program.  CMake-generated build
trees created for projects that use the INSTALL_* commands have packaging
support.  This program will generate the package.
 
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
 
  -G <generator>
      Use the specified generator to generate package.
 
      CPack may support multiple native packaging systems on certain
      platforms.  A generator is responsible for generating input files for
      particular system and invoking that systems.  Possible generator names
      are specified in the Generators section.
 
  -C <Configuration>
      Specify the project configuration
 
      This option specifies the configuration that the project was build
      with, for example 'Debug', 'Release'.
 
  -D <var>=<value>
      Set a CPack variable.
 
      Set a variable that can be used by the generator.
 
  --config <config file>
      Specify the config file.
 
      Specify the config file to use to create the package.  By default
      CPackConfig.cmake in the current directory will be used.
 
  --verbose,-V
      enable verbose output
 
      Run cpack with verbose output.
 
  --debug
      enable debug output (for CPack developers)
 
      Run cpack with debug output (for CPack developers).
 
  -P <package name>
      override/define CPACK_PACKAGE_NAME
 
      If the package name is not specified on cpack commmand line
      thenCPack.cmake defines it as CMAKE_PROJECT_NAME
 
  -R <package version>
      override/define CPACK_PACKAGE_VERSION
 
      If version is not specified on cpack command line thenCPack.cmake
      defines it from CPACK_PACKAGE_VERSION_[MAJOR|MINOR|PATCH]look into
      CPack.cmake for detail
 
  -B <package directory>
      override/define CPACK_PACKAGE_DIRECTORY
 
      The directory where CPack will be doing its packaging work.The
      resulting package will be found there.  Inside this directoryCPack
      creates '_CPack_Packages' sub-directory which is theCPack temporary
      directory.
 
  --vendor <vendor name>
      override/define CPACK_PACKAGE_VENDOR
 
      If vendor is not specified on cpack command line (or inside
      CMakeLists.txt) thenCPack.cmake defines it with a default value

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 inconsistent 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.
 
  break
      Break from an enclosing foreach or while loop.
 
        break()
 
      Breaks from an enclosing foreach loop or while loop
 
  cmake_minimum_required
      Set the minimum required version of cmake for a project.
 
        cmake_minimum_required(VERSION major[.minor[.patch[.tweak]]]
                                [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[.tweak]]])
 
      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[.tweak]])
 
      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 unset (unless variable
      CMAKE_POLICY_DEFAULT_CMP<NNNN> sets a default).  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(<input> <output>
                        [COPYONLY] [ESCAPE_QUOTES] [@ONLY]
                        [NEWLINE_STYLE [UNIX|DOS|WIN32|LF|CRLF] ])
 
      Copies a file <input> to file <output> and substitutes variable values
      referenced in the file content.  If <input> is a relative path it is
      evaluated with respect to the current source directory.  The <input>
      must be a file, not a directory.  If <output> is a relative path it is
      evaluated with respect to the current binary directory.  If <output>
      names an existing directory the input file is placed in that directory
      with its original name.
 
      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.  Any occurrences of
      #cmakedefine01 VAR will be replaced with either #define VAR 1 or
      #define VAR 0 depending on whether VAR evaluates to TRUE or FALSE in
      CMake.
 
      With NEWLINE_STYLE the line ending could be adjusted:
 
          'UNIX' or 'LF' for \n, 'DOS', 'WIN32' or 'CRLF' for \r\n.
 
      COPYONLY must not be used with NEWLINE_STYLE.
 
 
  else
      Starts the else portion of an if block.
 
        else(expression)
 
      See the if command.
 
  elseif
      Starts the elseif portion of an if block.

  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>]

                        [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.

              [EXPECTED_HASH ALGO=value] [EXPECTED_MD5 sum]
              [TLS_VERIFY on|off] [TLS_CAINFO file])
        file(UPLOAD filename url [INACTIVITY_TIMEOUT timeout]
              [TIMEOUT timeout] [STATUS status] [LOG log] [SHOW_PROGRESS])
 
      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.
 
      MD5, SHA1, SHA224, SHA256, SHA384, and SHA512 will compute a
      cryptographic hash of the content of a file.
 
      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.  (We do not recommend using GLOB to
      collect a list of source files from your source tree.  If no
      CMakeLists.txt file changes when a source is added or removed then the
      generated build system cannot know when to ask CMake to regenerate.)
 
      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
 
      RENAME moves a file or directory within a filesystem, replacing the
      destination atomically.
 
      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.  This command will also convert the native list
      delimiters for a list of paths like the PATH environment variable.
 
      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 should be specified as an integer.  The
      INACTIVITY_TIMEOUT specifies an integer number of seconds of
      inactivity after which the operation should terminate.  If
      EXPECTED_HASH ALGO=value is specified, the operation will verify that
      the downloaded file's actual hash matches the expected value, where
      ALGO is one of MD5, SHA1, SHA224, SHA256, SHA384, or SHA512.  If it
      does not match, the operation fails with an error.  ("EXPECTED_MD5
      sum" is short-hand for "EXPECTED_HASH MD5=sum".) If SHOW_PROGRESS is
      specified, progress information will be printed as status messages
      until the operation is complete.  For https URLs CMake must be built
      with OpenSSL.  TLS/SSL certificates are not checked by default.  Set
      TLS_VERIFY to ON to check certificates and/or use EXPECTED_HASH to
      verify downloaded content.  Set TLS_CAINFO to specify a custom
      Certificate Authority file.  If either TLS option is not given CMake
      will check variables CMAKE_TLS_VERIFY and CMAKE_TLS_CAINFO,
      respectively.
 
      UPLOAD will upload the given file to the given URL.  If LOG var is
      specified a log of the upload 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 should be specified as an integer.  The
      INACTIVITY_TIMEOUT specifies an integer number of seconds of
      inactivity after which the operation should terminate.  If
      SHOW_PROGRESS is specified, progress information will be printed as
      status messages until the operation is complete.
 
      The file() command also provides COPY and INSTALL signatures:
 
        file(<COPY|INSTALL> files... DESTINATION <dir>
              [FILE_PERMISSIONS permissions...]
              [DIRECTORY_PERMISSIONS permissions...]
              [NO_SOURCE_PERMISSIONS] [USE_SOURCE_PERMISSIONS]
              [FILES_MATCHING]
              [[PATTERN <pattern> | REGEX <regex>]
              [EXCLUDE] [PERMISSIONS permissions...]] [...])
 
      The COPY signature copies files, directories, and symlinks to a
      destination folder.  Relative input paths are evaluated with respect
      to the current source directory, and a relative destination is
      evaluated with respect to the current build directory.  Copying
      preserves input file timestamps, and optimizes out a file if it exists
      at the destination with the same timestamp.  Copying preserves input
      permissions unless explicit permissions or NO_SOURCE_PERMISSIONS are
      given (default is USE_SOURCE_PERMISSIONS).  See the install(DIRECTORY)
      command for documentation of permissions, PATTERN, REGEX, and EXCLUDE
      options.
 
      The INSTALL signature differs slightly from COPY: it prints status
      messages, and NO_SOURCE_PERMISSIONS is default.  Installation scripts
      generated by the install() command use this signature (with some
      undocumented options for internal use).
 
  find_file
      Find the full path to a file.
 
          find_file(<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_file(<VAR> name1 [PATHS path1
      path2 ...])
 
          find_file(
                    <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_file 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_file(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_file(<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/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
          <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/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
          <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/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
          <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.

      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

      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.
 
      If the global property FIND_LIBRARY_USE_LIB64_PATHS is set all search
      paths will be tested as normal, with "64/" appended, and with all
      matches of "lib/" replaced with "lib64/".  This property is
      automatically set for the platforms that are known to need it if at
      least one of the languages supported by the PROJECT command is
      enabled.
 
  find_package
      Load settings for an external project.
 
        find_package(<package> [version] [EXACT] [QUIET] [MODULE]
                      [REQUIRED] [[COMPONENTS] [components...]]
                      [OPTIONAL_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 MODULE option disables
      the second signature documented below.  The REQUIRED option stops
      processing with an error message if the package cannot be found.
 
      A package-specific list of required components may be listed after the
      COMPONENTS option (or after the REQUIRED option if present).
      Additional optional components may be listed after
      OPTIONAL_COMPONENTS.  Available components and their influence on
      whether a package is considered to be found are defined by the target
      package.
 
      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] and/or component list is given to a recursive invocation
      inside a find-module, the corresponding arguments are forwarded
      automatically from the outer call (including the EXACT flag for
      [version]).  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 and the MODULE option is not given the command
      proceeds to Config mode.
 
      The complete Config mode command signature is:
 
        find_package(<package> [version] [EXACT] [QUIET]
                      [REQUIRED] [[COMPONENTS] [components...]]
                      [CONFIG|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_PACKAGE_REGISTRY]
                      [NO_CMAKE_BUILDS_PATH]
                      [NO_CMAKE_SYSTEM_PATH]
                      [NO_CMAKE_SYSTEM_PACKAGE_REGISTRY]
                      [CMAKE_FIND_ROOT_PATH_BOTH |
                      ONLY_CMAKE_FIND_ROOT_PATH |
                      NO_CMAKE_FIND_ROOT_PATH])
 
      The CONFIG option may be used to skip Module mode explicitly and
      switch to Config mode.  It is synonymous to using NO_MODULE.  Config
      mode 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.
 
      All configuration files which have been considered by CMake while
      searching for an installation of the package with an appropriate
      version are stored in the cmake variable <package>_CONSIDERED_CONFIGS,
      the associated versions in <package>_CONSIDERED_VERSIONS.
 
      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 configuration 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.  A basic version file containing generic version
      matching code can be created using the macro
      write_basic_package_version_file(), see its documentation for more
      details.  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>/(lib/<arch>|lib|share)/cmake/<name>*/          (U)
        <prefix>/(lib/<arch>|lib|share)/<name>*/                (U)
        <prefix>/(lib/<arch>|lib|share)/<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).
      Paths with lib/<arch> are enabled if CMAKE_LIBRARY_ARCHITECTURE is
      set.  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.
 
          <package>_DIR
          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 paths stored in the CMake user package registry.  This can
      be skipped if NO_CMAKE_PACKAGE_REGISTRY is passed.  On Windows a
      <package> may appear under registry key
 
        HKEY_CURRENT_USER\Software\Kitware\CMake\Packages\<package>
 
      as a REG_SZ value, with arbitrary name, that specifies the directory
      containing the package configuration file.  On UNIX platforms a
      <package> may appear under the directory
 
        ~/.cmake/packages/<package>
 
      as a file, with arbitrary name, whose content specifies the directory
      containing the package configuration file.  See the export(PACKAGE)
      command to create user package registry entries for project build
      trees.
 
      7.  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
 
      8.  Search paths stored in the CMake system package registry.  This
      can be skipped if NO_CMAKE_SYSTEM_PACKAGE_REGISTRY is passed.  On
      Windows a <package> may appear under registry key
 
        HKEY_LOCAL_MACHINE\Software\Kitware\CMake\Packages\<package>
 
      as a REG_SZ value, with arbitrary name, that specifies the directory
      containing the package configuration file.  There is no system package
      registry on non-Windows platforms.
 
      9.  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.
 
      Every non-REQUIRED find_package() call can be disabled by setting the
      variable CMAKE_DISABLE_FIND_PACKAGE_<package> to TRUE.  See the
      documentation for the CMAKE_DISABLE_FIND_PACKAGE_<package> variable
      for more information.
 
      When loading a find module or package configuration file find_package
      defines variables to provide information about the call arguments (and
      restores their original state before returning):
 
        <package>_FIND_REQUIRED      = true if REQUIRED option was given
        <package>_FIND_QUIETLY      = true if QUIET option was given
        <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
        <package>_FIND_VERSION_EXACT = true if EXACT option was given
        <package>_FIND_COMPONENTS    = list of requested components
        <package>_FIND_REQUIRED_<c>  = true if component <c> is required
                                      false if component <c> is optional
 
      In Module mode the loaded find module is responsible to honor the
      request detailed by these variables; see the find module for details.
      In Config mode find_package handles REQUIRED, QUIET, and version
      options automatically but leaves it to the package configuration file
      to handle components in a way that makes sense for the package.  The
      package configuration file may set <package>_FOUND to false to tell
      find_package that component requirements are not satisfied.
 
      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]]
                    [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 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 ...])
 
          find_program(
                    <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 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.
 
      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>/[s]bin for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_PROGRAM_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.
 
          <prefix>/[s]bin for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_PROGRAM_PATH
          CMAKE_APPBUNDLE_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
         
 
      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>/[s]bin for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_PROGRAM_PATH
          CMAKE_SYSTEM_APPBUNDLE_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_PROGRAM.  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_program(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_program(<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.
 
  foreach
      Evaluate a group of commands for each value in a list.
 
        foreach(loop_var arg1 arg2 ...)
          COMMAND1(ARGS ...)
          COMMAND2(ARGS ...)
          ...
        endforeach(loop_var)
 
      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(loop_var RANGE total)
        foreach(loop_var RANGE start stop [step])
 
      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.
 
        foreach(loop_var IN [LISTS [list1 [...]]]
                            [ITEMS [item1 [...]]])
 
      Iterates over a precise list of items.  The LISTS option names
      list-valued variables to be traversed, including empty elements (an
      empty string is a zero-length list).  The ITEMS option ends argument
      parsing and includes all arguments following it in the iteration.
 
  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 past 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, VAR will be
      set to "NOTFOUND".  Some supported properties include: VARIABLES,
      CACHE_VARIABLES, COMMANDS, MACROS, and COMPONENTS.
 
      See also the more general get_property() command.
 
  get_directory_property
      Get a property of DIRECTORY scope.
 
        get_directory_property(<variable> [DIRECTORY <dir>] <prop-name>)
 
      Store a property of directory scope in the named variable.  If the
      property is not defined the empty-string is returned.  The DIRECTORY
      argument specifies another directory from which to retrieve the
      property value.  The specified directory must have already been
      traversed by CMake.
 
        get_directory_property(<variable> [DIRECTORY <dir>]
                                DEFINITION <var-name>)
 
      Get a variable definition from a directory.  This form is useful to
      get a variable definition from another directory.
 
      See also the more general get_property() command.
 
  get_filename_component
      Get a specific component of a full filename.
 
        get_filename_component(<VAR> FileName
                                PATH|ABSOLUTE|NAME|EXT|NAME_WE|REALPATH
                                [CACHE])
 
      Set <VAR> to be the path (PATH), file name (NAME), file extension
      (EXT), file name without extension (NAME_WE) of FileName, the full
      path (ABSOLUTE), or the full path with all symlinks resolved
      (REALPATH).  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(<VAR> FileName
                                PROGRAM [PROGRAM_ARGS <ARG_VAR>]
                                [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 <ARG_VAR>.  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>  |
                      CACHE    <entry>  |
                      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.
 
      CACHE scope must name one cache entry.
 
      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.
 
  if
      Conditionally execute a group of commands.
 
        if(expression)
          # then section.
          COMMAND1(ARGS ...)
          COMMAND2(ARGS ...)
          ...
        elseif(expression2)
          # elseif section.
          COMMAND1(ARGS ...)
          COMMAND2(ARGS ...)
          ...
        else(expression)
          # 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 expression in the
      else and endif clause is optional.  Long expressions can be used and
      there is a traditional order of precedence.  Parenthetical expressions
      are evaluated first followed by unary operators such as EXISTS,
      COMMAND, and DEFINED.  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(<constant>)
 
      True if the constant is 1, ON, YES, TRUE, Y, or a non-zero number.
      False if the constant is 0, OFF, NO, FALSE, N, IGNORE, NOTFOUND, '',
      or ends in the suffix '-NOTFOUND'.  Named boolean constants are
      case-insensitive.  If the argument is not one of these constants, it
      is treated as a variable:
 
        if(<variable>)
 
      True if the variable is defined to a value that is not a false
      constant.  False otherwise.  (Note macro arguments are not variables.)
 
        if(NOT <expression>)
 
      True if the expression is not true.
 
        if(<expr1> AND <expr2>)
 
      True if both expressions would be considered true individually.
 
        if(<expr1> OR <expr2>)
 
      True if either expression would be considered true individually.
 
        if(COMMAND command-name)
 
      True if the given name is a command, macro or function that can be
      invoked.
 
        if(POLICY policy-id)
 
      True if the given name is an existing policy (of the form CMP<NNNN>).
 
        if(TARGET target-name)
 
      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 the file
      time stamps are exactly the same, an IS_NEWER_THAN comparison returns
      true, so that any dependent build operations will occur in the event
      of a tie.  This includes the case of passing the same file name for
      both file1 and file2.
 
        if(IS_DIRECTORY directory-name)
 
      True if the given name is a directory.  Behavior is well-defined only
      for full paths.
 
        if(IS_SYMLINK file-name)
 
      True if the given name is a symbolic link.  Behavior is well-defined
      only for full paths.
 
        if(IS_ABSOLUTE path)
 
      True if the given path is an absolute path.
 
        if(<variable|string> MATCHES regex)
 
      True if the given string or variable's value matches the given regular
      expression.
 
        if(<variable|string> LESS <variable|string>)
        if(<variable|string> GREATER <variable|string>)
        if(<variable|string> EQUAL <variable|string>)
 
      True if the given string or variable's value is a valid number and the
      inequality or equality is true.
 
        if(<variable|string> STRLESS <variable|string>)
        if(<variable|string> STRGREATER <variable|string>)
        if(<variable|string> STREQUAL <variable|string>)
 
      True if the given string or variable's value is lexicographically less
      (or greater, or equal) than the string or variable on the right.
 
        if(<variable|string> VERSION_LESS <variable|string>)
        if(<variable|string> VERSION_EQUAL <variable|string>)
        if(<variable|string> VERSION_GREATER <variable|string>)
 
      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.
 
        if((expression) AND (expression OR (expression)))
 
      The expressions inside the parenthesis are evaluated first and then
      the remaining expression is evaluated as in the previous examples.
      Where there are nested parenthesis the innermost are evaluated as part
      of evaluating the expression that contains them.
 
      The if command was written very early in CMake's history, predating
      the ${} variable evaluation syntax, and for convenience evaluates
      variables named by its arguments as shown in the above signatures.
      Note that normal variable evaluation with ${} applies before the if
      command even receives the arguments.  Therefore code like
 
        set(var1 OFF)
        set(var2 "var1")
        if(${var2})
 
      appears to the if command as
 
        if(var1)
 
      and is evaluated according to the if(<variable>) case documented
      above.  The result is OFF which is false.  However, if we remove the
      ${} from the example then the command sees
 
        if(var2)
 
      which is true because var2 is defined to "var1" which is not a false
      constant.
 
      Automatic evaluation applies in the other cases whenever the
      above-documented signature accepts <variable|string>:
 
      1) The left hand argument to MATCHES is first checked to see if it is
      a defined variable, if so the variable's value is used, otherwise the
      original value is used.
 
      2) If the left hand argument to MATCHES is missing it returns false
      without error
 
      3) Both left and right hand arguments to LESS GREATER EQUAL are
      independently tested to see if they are defined variables, if so their
      defined values are used otherwise the original value is used.
 
      4) Both left and right hand arguments to STRLESS STREQUAL STRGREATER
      are independently tested to see if they are defined variables, if so
      their defined values are used otherwise the original value is used.
 
      5) Both left and right hand argumemnts to VERSION_LESS VERSION_EQUAL
      VERSION_GREATER are independently tested to see if they are defined
      variables, if so their defined values are used otherwise the original
      value is used.
 
      6) The right hand argument to NOT is tested to see if it is a boolean
      constant, if so the value is used, otherwise it is assumed to be a
      variable and it is dereferenced.
 
      7) The left and right hand arguments to AND OR are independently
      tested to see if they are boolean constants, if so they are used as
      such, otherwise they are assumed to be variables and are dereferenced.
 
 
 
  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 first in CMAKE_MODULE_PATH, then in the
      CMake module directory.  There is one exception to this: if the file
      which calls include() is located itself in the CMake module directory,
      then first the CMake module directory is searched and
      CMAKE_MODULE_PATH afterwards.  See also policy CMP0017.
 
      See the cmake_policy() command documentation for discussion of the
      NO_POLICY_SCOPE option.
 
  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.
 
      The list subcommands APPEND, INSERT, REMOVE_AT, REMOVE_ITEM,
      REMOVE_DUPLICATES, REVERSE and SORT may create new values for the list
      within the current CMake variable scope.  Similar to the SET command,
      the LIST command creates new variable values in the current scope,
      even if the list itself is actually defined in a parent scope.  To
      propagate the results of these operations upwards, use SET with
      PARENT_SCOPE, SET with CACHE INTERNAL, or some other means of value
      propagation.
 
      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.
 
 
  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 past 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([STATUS|WARNING|AUTHOR_WARNING|FATAL_ERROR|SEND_ERROR]
                "message to display" ...)
 
      The optional keyword determines the type of message:
 
        (none)        = Important information
        STATUS        = Incidental information
        WARNING        = CMake Warning, continue processing
        AUTHOR_WARNING = CMake Warning (dev), continue processing
        SEND_ERROR    = CMake Error, continue but skip generation
        FATAL_ERROR    = CMake Error, stop all processing
 
      The CMake command-line tool displays STATUS messages on stdout and all
      other message types on stderr.  The CMake GUI displays all messages in
      its log area.  The interactive dialogs (ccmake and CMakeSetup) show
      STATUS messages one at a time on a status line and other messages in
      interactive pop-up boxes.
 
      CMake Warning and Error message text displays using a simple markup
      language.  Non-indented text is formatted in line-wrapped paragraphs
      delimited by newlines.  Indented text is considered pre-formatted.
 
  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.
 
      If you have options that depend on the values of other options, see
      the module help for CMakeDependentOption.
 
  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
      Parse space-separated arguments into a semicolon-separated list.
 
        separate_arguments(<var> <UNIX|WINDOWS>_COMMAND "<args>")
 
      Parses a unix- or windows-style command-line string "<args>" and
      stores a semicolon-separated list of the arguments in <var>.  The
      entire command line must be given in one "<args>" argument.
 
      The UNIX_COMMAND mode separates arguments by unquoted whitespace.  It
      recognizes both single-quote and double-quote pairs.  A backslash
      escapes the next literal character (\" is "); there are no special
      escapes (\n is just n).
 
      The WINDOWS_COMMAND mode parses a windows command-line using the same
      syntax the runtime library uses to construct argv at startup.  It
      separates arguments by whitespace that is not double-quoted.
      Backslashes are literal unless they precede double-quotes.  See the
      MSDN article "Parsing C Command-Line Arguments" for details.
 
        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, cache or environment 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.  Normally, set will set a
      regular CMake variable.  If CACHE is present, then the <variable> is
      put in the cache instead, unless it is already in the cache.  See
      section 'Variable types in CMake' below for details of regular and
      cache variables and their interactions.  If CACHE is used, <type> and
      <docstring> are 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, the cache variable is marked as internal, and
      will not be shown to the user in tools like cmake-gui.  This is
      intended for values that should be persisted in the cache, but which
      users should not normally change.  INTERNAL implies FORCE.
 
      Normally, set(...CACHE...) creates cache variables, but does not
      modify them.  If FORCE is specified, the value of the cache variable
      is set, even if the variable is already in the cache.  This should
      normally be avoided, as it will remove any changes to the cache
      variable's value 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).  PARENT_SCOPE cannot be combined with CACHE.
 
      If <value> is not specified then the variable is removed instead of
      set.  See also: the unset() command.
 
        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.
 
      *** Variable types in CMake ***
 
      In CMake there are two types of variables: normal variables and cache
      variables.  Normal variables are meant for the internal use of the
      script (just like variables in most programming languages); they are
      not persisted across CMake runs.  Cache variables (unless set with
      INTERNAL) are mostly intended for configuration settings where the
      first CMake run determines a suitable default value, which the user
      can then override, by editing the cache with tools such as ccmake or
      cmake-gui.  Cache variables are stored in the CMake cache file, and
      are persisted across CMake runs.
 
      Both types can exist at the same time with the same name but different
      values.  When ${FOO} is evaluated, CMake first looks for a normal
      variable 'FOO' in scope and uses it if set.  If and only if no normal
      variable exists then it falls back to the cache variable 'FOO'.
 
      Some examples:
 
      The code 'set(FOO "x")' sets the normal variable 'FOO'.  It does not
      touch the cache, but it will hide any existing cache value 'FOO'.
 
      The code 'set(FOO "x" CACHE ...)' checks for 'FOO' in the cache,
      ignoring any normal variable of the same name.  If 'FOO' is in the
      cache then nothing happens to either the normal variable or the cache
      variable.  If 'FOO' is not in the cache, then it is added to the
      cache.
 
      Finally, whenever a cache variable is added or modified by a command,
      CMake also *removes* the normal variable of the same name from the
      current scope so that an immediately following evaluation of it will
      expose the newly cached value.
 
      Normally projects should avoid using normal and cache variables of the
      same name, as this interaction can be hard to follow.  However, in
      some situations it can be useful.  One example (used by some
      projects):
 
      A project has a subproject in its source tree.  The child project has
      its own CMakeLists.txt, which is included from the parent
      CMakeLists.txt using add_subdirectory().  Now, if the parent and the
      child project provide the same option (for example a compiler option),
      the parent gets the first chance to add a user-editable option to the
      cache.  Normally, the child would then use the same value that the
      parent uses.  However, it may be necessary to hard-code the value for
      the child project's option while still allowing the user to edit the
      value used by the parent project.  The parent project can achieve this
      simply by setting a normal variable with the same name as the option
      in a scope sufficient to hide the option's cache variable from the
      child completely.  The parent has already set the cache variable, so
      the child's set(...CACHE...) will do nothing, and evaluating the
      option variable will use the value from the normal variable, which
      hides the cache variable.
 
  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 ...]]    |
                      CACHE    [entry1 [entry2 ...]]>
                      [APPEND] [APPEND_STRING]
                      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.  Note that source
      file properties are visible only to targets added in the same
      directory (CMakeLists.txt).
 
      TEST scope may name zero or more existing tests.
 
      CACHE scope must name zero or more cache existing entries.
 
      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.If the APPEND_STRING option is given the string is append to any
      existing property value as string, i.e.  it results in a longer string
      and not a list of strings.
 
  site_name
      Set the given variable to the name of the computer.
 
        site_name(variable)
 
 
  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>

        string(RANDOM [LENGTH <length>] [ALPHABET <alphabet>]
                [RANDOM_SEED <seed>] <output variable>)
        string(FIND <string> <substring> <output variable> [REVERSE])
 
      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.
 
      MD5, SHA1, SHA224, SHA256, SHA384, and SHA512 will compute a
      cryptographic hash of the input string.
 
      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.  If length is -1
      the remainder of the string starting at begin will be returned.
 
      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.
      If an integer RANDOM_SEED is given, its value will be used to seed the
      random number generator.
 
      FIND will return the position where the given substring was found in
      the supplied string.  If the REVERSE flag was used, the command will
      search for the position of the last occurrence of the specified
      substring.
 
      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
          -        Inside brackets, specifies an inclusive range between
                    characters on either side e.g. [a-f] is [abcdef]
          *        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
                    by all regular expression-related commands, including
                    e.g. if( MATCHES ), in the variables CMAKE_MATCH_(0..9).
 
  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.

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.  ;-)
 
------------------------------------------------------------------------------
Standard CMake Modules
 
------------------------------------------------------------------------------
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.  By 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.  By 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 languages.
 
  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.
 
  FIND_LIBRARY_USE_OPENBSD_VERSIONING
      Whether FIND_LIBRARY should find OpenBSD-style shared libraries.
 
      This property is a boolean specifying whether the FIND_LIBRARY command
      should find shared libraries with OpenBSD-style versioned extension:
      ".so.<major>.<minor>".  The property is set to true on OpenBSD and
      false on other platforms.
 
  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.
 
  GLOBAL_DEPENDS_NO_CYCLES
      Disallow global target dependency graph cycles.
 
      CMake automatically analyzes the global inter-target dependency graph
      at the beginning of native build system generation.  It reports an
      error if the dependency graph contains a cycle that does not consist
      of all STATIC library targets.  This property tells CMake to disallow
      all cycles completely, even among static libraries.
 
  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.
 
  PREDEFINED_TARGETS_FOLDER
      Name of FOLDER for targets that are added automatically by CMake.
 
      If not set, CMake uses "CMakePredefinedTargets" as a default value for
      this property.  Targets such as INSTALL, PACKAGE and RUN_TESTS will be
      organized into this FOLDER.  See also the documentation for the FOLDER
      target property.
 
  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.
 
  RULE_LAUNCH_COMPILE
      Specify a launcher for compile rules.
 
      Makefile generators prefix compiler commands with the given launcher
      command line.  This is intended to allow launchers to intercept build
      problems with high granularity.  Non-Makefile generators currently
      ignore this property.
 
  RULE_LAUNCH_CUSTOM
      Specify a launcher for custom rules.
 
      Makefile generators prefix custom commands with the given launcher
      command line.  This is intended to allow launchers to intercept build
      problems with high granularity.  Non-Makefile generators currently
      ignore this property.
 
  RULE_LAUNCH_LINK
      Specify a launcher for link rules.
 
      Makefile generators prefix link and archive commands with the given
      launcher command line.  This is intended to allow launchers to
      intercept build problems with high granularity.  Non-Makefile
      generators currently ignore this property.
 
  RULE_MESSAGES
      Specify whether to report a message for each make rule.
 
      This property specifies whether Makefile generators should add a
      progress message describing what each build rule does.  If the
      property is not set the default is ON.  Set the property to OFF to
      disable granular messages and report only as each target completes.
      This is intended to allow scripted builds to avoid the build time cost
      of detailed reports.  If a CMAKE_RULE_MESSAGES cache entry exists its
      value initializes the value of this property.  Non-Makefile generators
      currently ignore 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.
 
  USE_FOLDERS
      Use the FOLDER target property to organize targets into folders.
 
      If not set, CMake treats this property as OFF by default.  CMake
      generators that are capable of organizing into a hierarchy of folders
      use the values of the FOLDER target property to name those folders.
      See also the documentation for the FOLDER target property.
 
  __CMAKE_DELETE_CACHE_CHANGE_VARS_
      Internal property
 
      Used to detect compiler changes, Do not set.
 
------------------------------------------------------------------------------
Properties on Cache Entries
 
  ADVANCED
      True if entry should be hidden by default in GUIs.
 
      This is a boolean value indicating whether the entry is considered
      interesting only for advanced configuration.  The mark_as_advanced()
      command modifies this property.
 
  HELPSTRING
      Help associated with entry in GUIs.
 
      This string summarizes the purpose of an entry to help users set it
      through a CMake GUI.
 
  MODIFIED
      Internal management property.  Do not set or get.
 
      This is an internal cache entry property managed by CMake to track
      interactive user modification of entries.  Ignore it.
 
  STRINGS
      Enumerate possible STRING entry values for GUI selection.
 
      For cache entries with type STRING, this enumerates a set of values.
      CMake GUIs may use this to provide a selection widget instead of a
      generic string entry field.  This is for convenience only.  CMake does
      not enforce that the value matches one of those listed.
 
  TYPE
      Widget type for entry in GUIs.
 
      Cache entry values are always strings, but CMake GUIs present widgets
      to help users set values.  The GUIs use this property as a hint to
      determine the widget type.  Valid TYPE values are:
 
        BOOL          = Boolean ON/OFF value.
        PATH          = Path to a directory.
        FILEPATH      = Path to a file.
        STRING        = Generic string value.
        INTERNAL      = Do not present in GUI at all.
        STATIC        = Value managed by CMake, do not change.
        UNINITIALIZED = Type not yet specified.
 
      Generally the TYPE of a cache entry should be set by the command which
      creates it (set, option, find_library, etc.).
 
  VALUE
      Value of a cache entry.
 
      This property maps to the actual value of a cache entry.  Setting this
      property always sets the value without checking, so use with care.
 
------------------------------------------------------------------------------
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 semicolon-separated
      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 definition
      values with spaces (but NMake does).
 
      Disclaimer: 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.  Known limitations include:
 
        #          - broken almost everywhere
        ;          - broken in VS IDE and Borland Makefiles
        ,          - broken in VS IDE
        %          - broken in some cases in NMake
        & |        - broken in some cases on MinGW
        ^ < > \"  - broken in most Make tools on Windows
 
      CMake does not reject these values outright because they do work in
      some cases.  Use with caution.
 
  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 property specifies the list of directories given so far to the
      include_directories command.  This property exists on directories and
      targets.  In addition to accepting values from the include_directories
      command, values may be set directly on any directory or any target
      using the set_property command.  A target gets its initial value for
      this property from the value of the directory property.  A directory
      gets its initial value from its parent directory if it has one.  Both
      directory and target property values are adjusted by calls to the
      include_directories command.
 
      The target property values are used by the generators to set the
      include paths for the compiler.  See also the include_directories
      command.
 
  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.
 
  INTERPROCEDURAL_OPTIMIZATION
      Enable interprocedural optimization for targets in a directory.
 
      If set to true, enables interprocedural optimizations if they are
      known to be supported by the compiler.
 
  INTERPROCEDURAL_OPTIMIZATION_<CONFIG>
      Per-configuration interprocedural optimization for a directory.
 
      This is a per-configuration version of INTERPROCEDURAL_OPTIMIZATION.
      If set, this property overrides the generic property for the named
      configuration.
 
  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.
 
  RULE_LAUNCH_COMPILE
      Specify a launcher for compile rules.
 
      See the global property of the same name for details.  This overrides
      the global property for a directory.
 
  RULE_LAUNCH_CUSTOM
      Specify a launcher for custom rules.
 
      See the global property of the same name for details.  This overrides
      the global property for a directory.
 
  RULE_LAUNCH_LINK
      Specify a launcher for link rules.
 
      See the global property of the same name for details.  This overrides
      the global property for a directory.
 
  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 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 semicolon-separated
      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 definition
      values with spaces (but NMake does).  Xcode does not support
      per-configuration definitions on source files.
 
      Disclaimer: 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.  Known limitations include:
 
        #          - broken almost everywhere
        ;          - broken in VS IDE and Borland Makefiles
        ,          - broken in VS IDE
        %          - broken in some cases in NMake
        & |        - broken in some cases on MinGW
        ^ < > \"  - broken in most Make tools on Windows
 
      CMake does not reject these values outright because they do work in
      some cases.  Use with caution.
 
  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.
 
  Fortran_FORMAT
      Set to FIXED or FREE to indicate the Fortran source layout.
 
      This property tells CMake whether a given Fortran source file uses
      fixed-format or free-format.  CMake will pass the corresponding format
      flag to the compiler.  Consider using the target-wide Fortran_FORMAT
      property if all source files in a target share the same format.
 
  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 terms 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.
 
  LABELS
      Specify a list of text labels associated with a source file.
 
      This property has meaning only when the source file is listed in a
      target whose LABELS property is also set.  No other semantics are
      currently specified.
 
  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.  Setting this
      property for a file means this file will be compiled.  Do not set this
      for header or files that should not be compiled.
 
  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, CFBundle, 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.  Module library targets with the BUNDLE
      property set are built as Mac OS X CFBundle bundles 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>".  For cfbundles the content
      folder is "<name>.bundle/Contents" (unless the extension is changed).
      See the PUBLIC_HEADER, PRIVATE_HEADER, and RESOURCE target properties
      for specifying files meant for Headers, PrivateHeaders, 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.
 
------------------------------------------------------------------------------
Properties on Targets
 
  <CONFIG>_OUTPUT_NAME
      Old per-configuration target file base name.
 
      This is a configuration-specific version of OUTPUT_NAME.  Use
      OUTPUT_NAME_<CONFIG> instead.
 
  <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.  Multi-configuration generators (VS, Xcode) append a
      per-configuration subdirectory to the specified directory.  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.
 
  ARCHIVE_OUTPUT_DIRECTORY_<CONFIG>
      Per-configuration output directory for ARCHIVE target files.
 
      This is a per-configuration version of ARCHIVE_OUTPUT_DIRECTORY, but
      multi-configuration generators (VS, Xcode) do NOT append a
      per-configuration subdirectory to the specified directory.  This
      property is initialized by the value of the variable
      CMAKE_ARCHIVE_OUTPUT_DIRECTORY_<CONFIG> if it is set when a target is
      created.
 
  ARCHIVE_OUTPUT_NAME
      Output name for ARCHIVE target files.
 
      This property specifies the base name for archive target files.  It
      overrides OUTPUT_NAME and OUTPUT_NAME_<CONFIG> properties.  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.
 
  ARCHIVE_OUTPUT_NAME_<CONFIG>
      Per-configuration output name for ARCHIVE target files.
 
      This is the configuration-specific version of ARCHIVE_OUTPUT_NAME.
 
  AUTOMOC
      Should the target be processed with automoc (for Qt projects).
 
      AUTOMOC is a boolean specifying whether CMake will handle the Qt moc
      preprocessor automatically, i.e.  without having to use the
      QT4_WRAP_CPP() macro.  Currently Qt4 is supported.  When this property
      is set to TRUE, CMake will scan the source files at build time and
      invoke moc accordingly.  If an #include statement like #include
      "moc_foo.cpp" is found, the Q_OBJECT class declaration is expected in
      the header, and moc is run on the header file.  If an #include
      statement like #include "foo.moc" is found, then a Q_OBJECT is
      expected in the current source file and moc is run on the file itself.
      Additionally, all header files are parsed for Q_OBJECT macros, and if
      found, moc is also executed on those files.  The resulting moc files,
      which are not included as shown above in any of the source files are
      included in a generated <targetname>_automoc.cpp file, which is
      compiled as part of the target.This property is initialized by the
      value of the variable CMAKE_AUTOMOC if it is set when a target is
      created.
 
      Additional command line options for moc can be set via the
      AUTOMOC_MOC_OPTIONS property.
 
      By setting the CMAKE_AUTOMOC_RELAXED_MODE variable to TRUE the rules
      for searching the files which will be processed by moc can be relaxed.
      See the documentation for this variable for more details.
 
  AUTOMOC_MOC_OPTIONS
      Additional options for moc when using automoc (see the AUTOMOC
      property)
 
      This property is only used if the AUTOMOC property is set to TRUE for
      this target.  In this case, it holds additional command line options
      which will be used when moc is executed during the build, i.e.  it is
      equivalent to the optional OPTIONS argument of the qt4_wrap_cpp()
      macro.
 
      By default it is empty.
 
  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.  This property is initialized by the value of the
      variable CMAKE_BUILD_WITH_INSTALL_RPATH if it is set when a target is
      created.
 
  BUNDLE
      This target is a CFBundle on the Mac.
 
      If a module library target has this property set to true it will be
      built as a CFBundle when built on the mac.  It will have the directory
      structure required for a CFBundle and will be suitable to be used for
      creating Browser Plugins or other application resources.
 
  BUNDLE_EXTENSION
      The file extension used to name a BUNDLE target on the Mac.
 
      The default value is "bundle" - you can also use "plugin" or whatever
      file extension is required by the host app for your bundle.
 
  COMPILE_DEFINITIONS
      Preprocessor definitions for compiling a target's sources.
 
      The COMPILE_DEFINITIONS property may be set to a semicolon-separated
      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 definition
      values with spaces (but NMake does).
 
      Contents of COMPILE_DEFINITIONS may use "generator expressions" with
      the syntax "$<...>".  Generator expressions are evaluted during build
      system generation to produce information specific to each build
      configuration.  Valid expressions are:
 
        $<0:...>                  = empty string (ignores "...")
        $<1:...>                  = content of "..."
        $<CONFIG:cfg>            = '1' if config is "cfg", else '0'
        $<CONFIGURATION>          = configuration name
        $<BOOL:...>              = '1' if the '...' is true, else '0'
        $<STREQUAL:a,b>          = '1' if a is STREQUAL b, else '0'
        $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
        $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
        $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
        $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
        $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)
 
      where "tgt" is the name of a target.  Target file expressions produce
      a full path, but _DIR and _NAME versions can produce the directory and
      file name components:
 
        $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
        $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
        $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>
 
     
 
        $<TARGET_PROPERTY:tgt,prop>  = The value of the property prop
 
      on the target tgt.  Note that tgt is not added as a dependency of
 
      the target this expression is evaluated on.
 
      Boolean expressions:
 
        $<AND:?[,?]...>          = '1' if all '?' are '1', else '0'
        $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
        $<NOT:?>                  = '0' if '?' is '1', else '1'
 
      where '?' is always either '0' or '1'.
 
      Expressions with an implicit 'this' target:
 
        $<TARGET_PROPERTY:prop>  = The value of the property prop on
 
      the target on which the generator expression is evaluated.
 
      Disclaimer: 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.  Known limitations include:
 
        #          - broken almost everywhere
        ;          - broken in VS IDE and Borland Makefiles
        ,          - broken in VS IDE
        %          - broken in some cases in NMake
        & |        - broken in some cases on MinGW
        ^ < > \"  - broken in most Make tools on Windows
 
      CMake does not reject these values outright because they do work in
      some cases.  Use with caution.
 
  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 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.  For non-DLL platforms that
      require all symbols to be resolved at link time, such as Mac OS X, the
      module will "link" to the executable using a flag like
      "-bundle_loader".  For other non-DLL platforms the link rule is simply
      ignored since the dynamic loader will automatically bind symbols when
      the module is loaded.
 
  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.
 
  FOLDER
      Set the folder name.  Use to organize targets in an IDE.
 
      Targets with no FOLDER property will appear as top level entities in
      IDEs like Visual Studio.  Targets with the same FOLDER property value
      will appear next to each other in a folder of that name.  To nest
      folders, use FOLDER values such as 'GUI/Dialogs' with '/' characters
      separating folder levels.
 
  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_FORMAT
      Set to FIXED or FREE to indicate the Fortran source layout.
 
      This property tells CMake whether the Fortran source files in a target
      use fixed-format or free-format.  CMake will pass the corresponding
      format flag to the compiler.  Use the source-specific Fortran_FORMAT
      property to change the format of a specific source file.  If the
      variable CMAKE_Fortran_FORMAT is set when a target is created its
      value is used to initialize this property.
 
  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.
 
      Note that some compilers will automatically search the module output
      directory for modules USEd during compilation but others will not.  If
      your sources USE modules their location must be specified by
      INCLUDE_DIRECTORIES regardless of 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.
 
  GNUtoMS
      Convert GNU import library (.dll.a) to MS format (.lib).
 
      When linking a shared library or executable that exports symbols using
      GNU tools on Windows (MinGW/MSYS) with Visual Studio installed convert
      the import library (.dll.a) from GNU to MS format (.lib).  Both import
      libraries will be installed by install(TARGETS) and exported by
      install(EXPORT) and export() to be linked by applications with either
      GNU- or MS-compatible tools.
 
      If the variable CMAKE_GNUtoMS is set when a target is created its
      value is used to initialize this property.  The variable must be set
      prior to the first command that enables a language such as project()
      or enable_language().  CMake provides the variable as an option to the
      user automatically when configuring on Windows with GNU tools.
 
  HAS_CXX
      Link the target using the C++ linker tool (obsolete).
 
      This is equivalent to setting the LINKER_LANGUAGE property to CXX.
      See that property's documentation for details.
 
  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.
 
      Set this to the list of 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.
 
      Set this to the location of the ".lib" part of a windows DLL.  Ignored
      for non-imported targets.
 
  IMPORTED_IMPLIB_<CONFIG>
      <CONFIG>-specific version of IMPORTED_IMPLIB property.
 
      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.  Set this property to the list of 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>
      <CONFIG>-specific version of IMPORTED_LINK_DEPENDENT_LIBRARIES.
 
      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_LANGUAGES
      Languages compiled into an IMPORTED static library.
 
      Set this to the list of languages of source files compiled to produce
      a STATIC IMPORTED library (such as "C" or "CXX").  CMake accounts for
      these languages when computing how to link a target to the imported
      library.  For example, when a C executable links to an imported C++
      static library CMake chooses the C++ linker to satisfy language
      runtime dependencies of the static library.
 
      This property is ignored for targets that are not STATIC libraries.
      This property is ignored for non-imported targets.
 
  IMPORTED_LINK_INTERFACE_LANGUAGES_<CONFIG>
      <CONFIG>-specific version of IMPORTED_LINK_INTERFACE_LANGUAGES.
 
      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.
 
      Set this to the list of 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>
      <CONFIG>-specific version of IMPORTED_LINK_INTERFACE_LIBRARIES.
 
      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_MULTIPLICITY
      Repetition count for cycles of IMPORTED static libraries.
 
      This is LINK_INTERFACE_MULTIPLICITY for IMPORTED targets.
 
  IMPORTED_LINK_INTERFACE_MULTIPLICITY_<CONFIG>
      <CONFIG>-specific version of IMPORTED_LINK_INTERFACE_MULTIPLICITY.
 
      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.
 
      Set this to 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.
 
      Projects may skip IMPORTED_LOCATION if the configuration-specific
      property IMPORTED_LOCATION_<CONFIG> is set.  To get the location of an
      imported target read one of the LOCATION or LOCATION_<CONFIG>
      properties.
 
  IMPORTED_LOCATION_<CONFIG>
      <CONFIG>-specific version of IMPORTED_LOCATION property.
 
      Configuration names correspond to those provided by the project from
      which the target is imported.
 
  IMPORTED_NO_SONAME
      Specifies that an IMPORTED shared library target has no "soname".
 
      Set this property to true for an imported shared library file that has
      no "soname" field.  CMake may adjust generated link commands for some
      platforms to prevent the linker from using the path to the library in
      place of its missing soname.  Ignored for non-imported targets.
 
  IMPORTED_NO_SONAME_<CONFIG>
      <CONFIG>-specific version of IMPORTED_NO_SONAME property.
 
      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.
 
      Set this to 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>
      <CONFIG>-specific version of IMPORTED_SONAME property.
 
      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.
 
  INCLUDE_DIRECTORIES
      List of preprocessor include file search directories.
 
      This property specifies the list of directories given so far to the
      include_directories command.  This property exists on directories and
      targets.  In addition to accepting values from the include_directories
      command, values may be set directly on any directory or any target
      using the set_property command.  A target gets its initial value for
      this property from the value of the directory property.  A directory
      gets its initial value from its parent directory if it has one.  Both
      directory and target property values are adjusted by calls to the
      include_directories command.
 
      The target property values are used by the generators to set the
      include paths for the compiler.  See also the include_directories
      command.
 
      Contents of INCLUDE_DIRECTORIES may use "generator expressions" with
      the syntax "$<...>".  Generator expressions are evaluted during build
      system generation to produce information specific to each build
      configuration.  Valid expressions are:
 
        $<0:...>                  = empty string (ignores "...")
        $<1:...>                  = content of "..."
        $<CONFIG:cfg>            = '1' if config is "cfg", else '0'
        $<CONFIGURATION>          = configuration name
        $<BOOL:...>              = '1' if the '...' is true, else '0'
        $<STREQUAL:a,b>          = '1' if a is STREQUAL b, else '0'
        $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
        $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
        $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
        $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
        $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)
 
      where "tgt" is the name of a target.  Target file expressions produce
      a full path, but _DIR and _NAME versions can produce the directory and
      file name components:
 
        $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
        $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
        $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>
 
     
 
        $<TARGET_PROPERTY:tgt,prop>  = The value of the property prop
 
      on the target tgt.  Note that tgt is not added as a dependency of
 
      the target this expression is evaluated on.
 
      Boolean expressions:
 
        $<AND:?[,?]...>          = '1' if all '?' are '1', else '0'
        $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
        $<NOT:?>                  = '0' if '?' is '1', else '1'
 
      where '?' is always either '0' or '1'.
 
      Expressions with an implicit 'this' target:
 
        $<TARGET_PROPERTY:prop>  = The value of the property prop on
 
      the target on which the generator expression is evaluated.
 
 
  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).  This property is initialized
      by the value of the variable CMAKE_INSTALL_RPATH if it is set when a
      target is created.
 
  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.  This property is initialized by the value of
      the variable CMAKE_INSTALL_RPATH_USE_LINK_PATH if it is set when a
      target is created.
 
  INTERPROCEDURAL_OPTIMIZATION
      Enable interprocedural optimization for a target.
 
      If set to true, enables interprocedural optimizations if they are
      known to be supported by the compiler.
 
  INTERPROCEDURAL_OPTIMIZATION_<CONFIG>
      Per-configuration interprocedural optimization for a target.
 
      This is a per-configuration version of INTERPROCEDURAL_OPTIMIZATION.
      If set, this property overrides the generic property for the named
      configuration.
 
  LABELS
      Specify a list of text labels associated with a target.
 
      Target label semantics are currently unspecified.
 
  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.  Multi-configuration generators (VS, Xcode) append a
      per-configuration subdirectory to the specified directory.  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.
 
  LIBRARY_OUTPUT_DIRECTORY_<CONFIG>
      Per-configuration output directory for LIBRARY target files.
 
      This is a per-configuration version of LIBRARY_OUTPUT_DIRECTORY, but
      multi-configuration generators (VS, Xcode) do NOT append a
      per-configuration subdirectory to the specified directory.  This
      property is initialized by the value of the variable
      CMAKE_LIBRARY_OUTPUT_DIRECTORY_<CONFIG> if it is set when a target is
      created.
 
  LIBRARY_OUTPUT_NAME
      Output name for LIBRARY target files.
 
      This property specifies the base name for library target files.  It
      overrides OUTPUT_NAME and OUTPUT_NAME_<CONFIG> properties.  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.
 
  LIBRARY_OUTPUT_NAME_<CONFIG>
      Per-configuration output name for LIBRARY target files.
 
      This is the configuration-specific version of LIBRARY_OUTPUT_NAME.
 
  LINKER_LANGUAGE
      Specifies language whose compiler will invoke the linker.
 
      For executables, shared libraries, and modules, this sets the language
      whose compiler is used to link the target (such as "C" or "CXX").  A
      typical value for an executable is the language of the source file
      providing the program entry point (main).  If not set, the language
      with the highest linker preference value is the default.  See
      documentation of CMAKE_<LANG>_LINKER_PREFERENCE variables.
 
  LINK_DEPENDS
      Additional files on which a target binary depends for linking.
 
      Specifies a semicolon-separated list of full-paths to files on which
      the link rule for this target depends.  The target binary will be
      linked if any of the named files is newer than it.
 
      This property is ignored by non-Makefile generators.  It is intended
      to specify dependencies on "linker scripts" for custom Makefile link
      rules.
 
  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 explicit 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 initialized by the
      value of the variable CMAKE_LINK_INTERFACE_LIBRARIES if it is set when
      a target is created.  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_INTERFACE_MULTIPLICITY
      Repetition count for STATIC libraries with cyclic dependencies.
 
      When linking to a STATIC library target with cyclic dependencies the
      linker may need to scan more than once through the archives in the
      strongly connected component of the dependency graph.  CMake by
      default constructs the link line so that the linker will scan through
      the component at least twice.  This property specifies the minimum
      number of scans if it is larger than the default.  CMake uses the
      largest value specified by any target in a component.
 
  LINK_INTERFACE_MULTIPLICITY_<CONFIG>
      Per-configuration repetition count for cycles of STATIC libraries.
 
      This is the configuration-specific version of
      LINK_INTERFACE_MULTIPLICITY.  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 CMake adds an option at the
      end of the library list (if necessary) to set the linker search type
      back to its starting type.  This property switches the final linker
      search type to -Bstatic regardless of how it started.  See also
      LINK_SEARCH_START_STATIC.
 
  LINK_SEARCH_START_STATIC
      Assume the linker looks for static libraries by default.
 
      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
      assumed to be -Bdynamic at the beginning of the library list.  This
      property switches the assumption to -Bstatic.  It is intended for use
      when linking an executable statically (e.g.  with the GNU -static
      option).  See also LINK_SEARCH_END_STATIC.
 
  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.  In
      CMake 2.8.4 and above add_custom_command recognizes generator
      expressions to refer to target locations anywhere in the command.
      Therefore this property is not needed for creating custom commands.
 
      Do not set properties that affect the location of a target after
      reading this property.  These include properties whose names match
      "(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIRECTORY)(_<CONFIG>)?",
      "(IMPLIB_)?(PREFIX|SUFFIX)", or "LINKER_LANGUAGE".  Failure to follow
      this rule is not diagnosed and leaves the location of the target
      undefined.
 
  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.
 
      Do not set properties that affect the location of a target after
      reading this property.  These include properties whose names match
      "(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIRECTORY)(_<CONFIG>)?",
      "(IMPLIB_)?(PREFIX|SUFFIX)", or "LINKER_LANGUAGE".  Failure to follow
      this rule is not diagnosed and leaves the location of the target
      undefined.
 
  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.  This
      property is initialized by the value of the variable
      CMAKE_MACOSX_BUNDLE if it is set when a target is created.
 
  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.
 
      Set this to the list of 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
      this property is set and no matching configurations are available,
      then the imported target is considered to be not found.  This property
      is ignored for non-imported targets.
 
  NO_SONAME
      Whether to set "soname" when linking a shared library or module.
 
      Enable this boolean property if a generated shared library or module
      should not have "soname" set.  Default is to set "soname" on all
      shared libraries and modules as long as the platform supports it.
      Generally, use this property only for leaf private libraries or
      plugins.  If you use it on normal shared libraries which other targets
      link against, on some platforms a linker will insert a full path to
      the library (as specified at link time) into the dynamic section of
      the dependent binary.  Therefore, once installed, dynamic loader may
      eventually fail to locate the library for the binary.
 
  OSX_ARCHITECTURES
      Target specific architectures for OS X.
 
      The OSX_ARCHITECTURES property sets the target binary architecture for
      targets on OS X.  This property is initialized by the value of the
      variable CMAKE_OSX_ARCHITECTURES if it is set when a target is
      created.  Use OSX_ARCHITECTURES_<CONFIG> to set the binary
      architectures on a per-configuration basis.  <CONFIG> is an upper-case
      name (ex: "OSX_ARCHITECTURES_DEBUG").
 
  OSX_ARCHITECTURES_<CONFIG>
      Per-configuration OS X binary architectures for a target.
 
      This property is the configuration-specific version of
      OSX_ARCHITECTURES.
 
  OUTPUT_NAME
      Output name for target files.
 
      This sets the base name for output files created for an executable or
      library target.  If not set, the logical target name is used by
      default.
 
  OUTPUT_NAME_<CONFIG>
      Per-configuration target file base name.
 
      This is the configuration-specific version of OUTPUT_NAME.
 
  PDB_NAME
      Output name for MS debug symbols .pdb file.
 
      Set the base name for debug symbols file created for an executable or
      library target.  If not set, the logical target name is used by
      default.
 
      This property is not implemented by the Visual Studio 6 generator.
 
  PDB_NAME_<CONFIG>
      Per-configuration name for MS debug symbols .pdb file.
 
      This is the configuration-specific version of PDB_NAME.
 
      This property is not implemented by the Visual Studio 6 generator.
 
  PDB_OUTPUT_DIRECTORY
      Output directory for MS debug symbols .pdb files.
 
      This property specifies the directory into which the MS debug symbols
      will be placed.  This property is initialized by the value of the
      variable CMAKE_PDB_OUTPUT_DIRECTORY if it is set when a target is
      created.
 
      This property is not implemented by the Visual Studio 6 generator.
 
  PDB_OUTPUT_DIRECTORY_<CONFIG>
      Per-configuration output directory for MS debug symbols .pdb files.
 
      This is a per-configuration version of PDB_OUTPUT_DIRECTORY, but
      multi-configuration generators (VS, Xcode) do NOT append a
      per-configuration subdirectory to the specified directory.  This
      property is initialized by the value of the variable
      CMAKE_PDB_OUTPUT_DIRECTORY_<CONFIG> if it is set when a target is
      created.
 
      This property is not implemented by the Visual Studio 6 generator.
 
  POSITION_INDEPENDENT_CODE
      Whether to create a position-independent target
 
      The POSITION_INDEPENDENT_CODE property determines whether position
      independent executables or shared libraries will be created.  This
      property is true by default for SHARED and MODULE library targets and
      false otherwise.  This property is initialized by the value of the
      variable CMAKE_POSITION_INDEPENDENT_CODE if it is set when a target is
      created.
 
  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
      Studio.
 
  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.
 
  RULE_LAUNCH_COMPILE
      Specify a launcher for compile rules.
 
      See the global property of the same name for details.  This overrides
      the global and directory property for a target.
 
  RULE_LAUNCH_CUSTOM
      Specify a launcher for custom rules.
 
      See the global property of the same name for details.  This overrides
      the global and directory property for a target.
 
  RULE_LAUNCH_LINK
      Specify a launcher for link rules.
 
      See the global property of the same name for details.  This overrides
      the global and directory property for a target.
 
  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.  Multi-configuration generators (VS, Xcode) append a
      per-configuration subdirectory to the specified directory.  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.
 
  RUNTIME_OUTPUT_DIRECTORY_<CONFIG>
      Per-configuration output directory for RUNTIME target files.
 
      This is a per-configuration version of RUNTIME_OUTPUT_DIRECTORY, but
      multi-configuration generators (VS, Xcode) do NOT append a
      per-configuration subdirectory to the specified directory.  This
      property is initialized by the value of the variable
      CMAKE_RUNTIME_OUTPUT_DIRECTORY_<CONFIG> if it is set when a target is
      created.
 
  RUNTIME_OUTPUT_NAME
      Output name for RUNTIME target files.
 
      This property specifies the base name for runtime target files.  It
      overrides OUTPUT_NAME and OUTPUT_NAME_<CONFIG> properties.  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.
 
  RUNTIME_OUTPUT_NAME_<CONFIG>
      Per-configuration output name for RUNTIME target files.
 
      This is the configuration-specific version of RUNTIME_OUTPUT_NAME.
 
  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.
      This property is initialized by the value of the variable
      CMAKE_SKIP_BUILD_RPATH if it is set when a target is created.
 
  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.
      SOVERSION is ignored if NO_SONAME property is set.  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.
 
  STATIC_LIBRARY_FLAGS_<CONFIG>
      Per-configuration flags for creating a static library.
 
      This is the configuration-specific version of STATIC_LIBRARY_FLAGS.
 
  SUFFIX
      What comes after the target name.
 
      A target property that can be set to override the suffix (such as
      ".so" or ".exe") on the name of a library, module or executable.
 
  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_DOTNET_REFERENCES
      Visual Studio managed project .NET references
 
      Adds one or more semicolon-delimited .NET references to a generated
      Visual Studio project.  For example, "System;System.Windows.Forms".
 
  VS_GLOBAL_<variable>
      Visual Studio project-specific global variable.
 
      Tell the Visual Studio generator to set the global variable
      '<variable>' to a given value in the generated Visual Studio project.
      Ignored on other generators.  Qt integration works better if
      VS_GLOBAL_QtVersion is set to the version FindQt4.cmake found.  For
      example, "4.7.3"
 
  VS_GLOBAL_KEYWORD
      Visual Studio project keyword.
 
      Sets the "keyword" attribute for a generated Visual Studio project.
      Defaults to "Win32Proj".  You may wish to override this value with
      "ManagedCProj", for example, in a Visual Studio managed C++ unit test
      project.
 
  VS_GLOBAL_PROJECT_TYPES
      Visual Studio project type(s).
 
      Can be set to one or more UUIDs recognized by Visual Studio to
      indicate the type of project.  This value is copied verbatim into the
      generated project file.  Example for a managed C++ unit testing
      project:
 
        {3AC096D0-A1C2-E12C-1390-A8335801FDAB};{8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942}
 
      UUIDs are semicolon-delimited.
 
  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_AUXPATH
      Visual Studio Source Code Control Aux Path.
 
      Can be set to change the visual studio source code control auxpath
      property.
 
  VS_SCC_LOCALPATH
      Visual Studio Source Code Control Local Path.
 
      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.
 
  VS_WINRT_EXTENSIONS
      Visual Studio project C++/CX language extensions for Windows Runtime
 
      Can be set to enable C++/CX language extensions.
 
  VS_WINRT_REFERENCES
      Visual Studio project Windows Runtime Metadata references
 
      Adds one or more semicolon-delimited WinRT references to a generated
      Visual Studio project.  For example, "Windows;Windows.UI.Core".
 
  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 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.  This property is
      initialized by the value of the variable CMAKE_WIN32_EXECUTABLE if it
      is set when a target is created.
 
  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
 
  ATTACHED_FILES
      Attach a list of files to a dashboard submission.
 
      Set this property to a list of files that will be encoded and
      submitted to the dashboard as an addition to the test result.
 
  ATTACHED_FILES_ON_FAIL
      Attach a list of files to a dashboard submission if the test fails.
 
      Same as ATTACHED_FILES, but these files will only be included if the
      test does not pass.
 
  COST
      Set this to a floating point value.  Tests in a test set will be run
      in descending order of cost.
 
      This property describes the cost of a test.  You can explicitly set
      this value; tests with higher COST values will run first.
 
  DEPENDS
      Specifies that this test should only be run after the specified list
      of tests.
 
      Set this to a list of tests that must finish before this test is run.
 
  ENVIRONMENT
      Specify environment variables that should be defined for running a
      test.
 
      If set to a list of environment variables and values of the form
      MYVAR=value those environment variables will be defined while running
      the test.  The environment is restored to its previous state after the
      test is done.
 
  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"
 
  LABELS
      Specify a list of text labels associated with a test.
 
      The list is reported in dashboard submissions.
 
  MEASUREMENT
      Specify a CDASH measurement and value to be reported for a test.
 
      If set to a name then that name will be reported to CDASH 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.
 
  PROCESSORS
      How many process slots this test requires
 
      Denotes the number of processors that this test will require.  This is
      typically used for MPI tests, and should be used in conjunction with
      the ctest_test PARALLEL_LEVEL option.
 
  REQUIRED_FILES
      List of files required to run the test.
 
      If set to a list of files, the test will not be run unless all of the
      files exist.
 
  RESOURCE_LOCK
      Specify a list of resources that are locked by this test.
 
      If multiple tests specify the same resource lock, they are guaranteed
      not to run concurrently.
 
  RUN_SERIAL
      Do not run this test in parallel with any other test.
 
      Use this option in conjunction with the ctest_test PARALLEL_LEVEL
      option to specify that this test should not be run in parallel with
      any other tests.
 
  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 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.
 
  WORKING_DIRECTORY
      The directory from which the test executable will be called.
 
      If this is not set it is called from the directory the test executable
      is located in.
 
------------------------------------------------------------------------------
Variables
 
  CPACK_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION
      Ask CPack to error out as soon as a file with absolute INSTALL
      DESTINATION is encountered.
 
      The fatal error is emitted before the installation of the offending
      file takes place.  Some CPack generators, like NSIS,enforce this
      internally.  This variable triggers the definition
      ofCMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION when CPack runsVariables
      common to all CPack generators
 
------------------------------------------------------------------------------
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_ABSOLUTE_DESTINATION_FILES
      List of files which have been installed using an ABSOLUTE DESTINATION
      path.
 
      This variable is defined by CMake-generated cmake_install.cmake
      scripts.  It can be used (read-only) by program or script that source
      those install scripts.  This is used by some CPack generators (e.g.
      RPM).
 
  CMAKE_AUTOMOC_RELAXED_MODE
      Switch between strict and relaxed automoc mode.
 
      By default, automoc behaves exactly as described in the documentation
      of the AUTOMOC target property.  When set to TRUE, it accepts more
      input and tries to find the correct input file for moc even if it
      differs from the documented behaviour.  In this mode it e.g.  also
      checks whether a header file is intended to be processed by moc when a
      "foo.moc" file has been included.
 
      Relaxed mode has to be enabled for KDE4 compatibility.
 
  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_DISABLE_FIND_PACKAGE_<PackageName>
      Variable for disabling find_package() calls.
 
      Every non-REQUIRED find_package() call in a project can be disabled by
      setting the variable CMAKE_DISABLE_FIND_PACKAGE_<PackageName> to TRUE.
      This can be used to build a project without an optional package,
      although that package is installed.
 
      This switch should be used during the initial CMake run.  Otherwise if
      the package has already been found in a previous CMake run, the
      variables which have been stored in the cache will still be there.  In
      the case it is recommended to remove the cache variables for this
      package from the cache using the cache editor or cmake -U
 
  CMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION
      Ask cmake_install.cmake script to error out as soon as a file with
      absolute INSTALL DESTINATION is encountered.
 
      The fatal error is emitted before the installation of the offending
      file takes place.  This variable is used by CMake-generated
      cmake_install.cmake scripts.  If ones set this variable to ON while
      running the script, it may get fatal error messages from the script.
 
  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_FIND_PACKAGE_WARN_NO_MODULE
      Tell find_package to warn if called without an explicit mode.
 
      If find_package is called without an explicit mode option (MODULE,
      CONFIG or NO_MODULE) and no Find<pkg>.cmake module is in
      CMAKE_MODULE_PATH then CMake implicitly assumes that the caller
      intends to search for a package configuration file.  If no package
      configuration file is found then the wording of the failure message
      must account for both the case that the package is really missing and
      the case that the project has a bug and failed to provide the intended
      Find module.  If instead the caller specifies an explicit mode option
      then the failure message can be more specific.
 
      Set CMAKE_FIND_PACKAGE_WARN_NO_MODULE to TRUE to tell find_package to
      warn when it implicitly assumes Config mode.  This helps developers
      enforce use of an explicit mode in all calls to find_package within a
      project.
 
  CMAKE_IGNORE_PATH
      Path to be ignored by FIND_XXX() commands.
 
      Specifies directories to be ignored by searches in FIND_XXX()
      commands.  This is useful in cross-compiled environments where some
      system directories contain incompatible but possibly linkable
      libraries.  For example, on cross-compiled cluster environments, this
      allows a user to ignore directories containing libraries meant for the
      front-end machine that modules like FindX11 (and others) would
      normally search.  By default this is empty; it is intended to be set
      by the project.  Note that CMAKE_IGNORE_PATH takes a list of directory
      names, NOT a list of prefixes.  If you want to ignore paths under
      prefixes (bin, include, lib, etc.), you'll need to specify them
      explicitly.  See also CMAKE_PREFIX_PATH, CMAKE_LIBRARY_PATH,
      CMAKE_INCLUDE_PATH, CMAKE_PROGRAM_PATH.
 
  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_DEFAULT_COMPONENT_NAME
      Default component used in install() commands.
 
      If an install() command is used without the COMPONENT argument, these
      files will be grouped into a default component.  The name of this
      default install component will be taken from this variable.  It
      defaults to "Unspecified".
 
  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.
 
      On UNIX one can use the DESTDIR mechanism in order to relocate the
      whole installation.  DESTDIR means DESTination DIRectory.  It is
      commonly used by makefile users in order to install software at
      non-default location.  It is usually invoked like this:
 
        make DESTDIR=/home/john install
 
      which will install the concerned software using the installation
      prefix, e.g.  "/usr/local" pre-pended with the DESTDIR value which
      finally gives "/home/john/usr/local".
 
      WARNING: DESTDIR may not be used on Windows because installation
      prefix usually contains a drive letter like in "C:/Program Files"
      which cannot be pre-pended with some other prefix.
 
  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 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 used 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
      List of directories to search for CMake modules.
 
      Commands like include() and find_package() search for files in
      directories listed by this variable before checking the default
      modules that come with CMake.
 
  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_POLICY_DEFAULT_CMP<NNNN>
      Default for CMake Policy CMP<NNNN> when it is otherwise left unset.
 
      Commands cmake_minimum_required(VERSION) and cmake_policy(VERSION) by
      default leave policies introduced after the given version unset.  Set
      CMAKE_POLICY_DEFAULT_CMP<NNNN> to OLD or NEW to specify the default
      for policy CMP<NNNN>, where <NNNN> is the policy number.
 
      This variable should not be set by a project in CMake code; use
      cmake_policy(SET) instead.  Users running CMake may set this variable
      in the cache (e.g.  -DCMAKE_POLICY_DEFAULT_CMP<NNNN>=<OLD|NEW>) to set
      a policy not otherwise set by the project.  Set to OLD to quiet a
      policy warning while using old behavior or to NEW to try building the
      project with new behavior.
 
  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_SKIP_INSTALL_ALL_DEPENDENCY
      Don't make the install target depend on the all target.
 
      By default, the "install" target depends on the "all" target.  This
      has the effect, that when "make install" is invoked or INSTALL is
      built, first the "all" target is built, then the installation starts.
      If CMAKE_SKIP_INSTALL_ALL_DEPENDENCY is set to TRUE, this dependency
      is not created, so the installation process will start immediately,
      independent from whether the project has been completely built or not.
 
  CMAKE_SYSTEM_IGNORE_PATH
      Path to be ignored by FIND_XXX() commands.
 
      Specifies directories to be ignored by searches in FIND_XXX()
      commands.  This is useful in cross-compiled environments where some
      system directories contain incompatible but possibly linkable
      libraries.  For example, on cross-compiled cluster environments, this
      allows a user to ignore directories containing libraries meant for the
      front-end machine that modules like FindX11 (and others) would
      normally search.  By default this contains a list of directories
      containing incompatible binaries for the host system.  See also
      CMAKE_SYSTEM_PREFIX_PATH, CMAKE_SYSTEM_LIBRARY_PATH,
      CMAKE_SYSTEM_INCLUDE_PATH, and CMAKE_SYSTEM_PROGRAM_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_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, and CMAKE_SYSTEM_IGNORE_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 CMake file that overrides platform information.
 
      CMake loads the specified file while enabling support for each
      language from either the project() or enable_language() commands.  It
      is loaded after CMake's builtin compiler and platform information
      modules have been loaded but before the information is used.  The file
      may set platform information variables to override CMake's defaults.
 
      This feature is intended for use only in overriding information
      variables that must be set before CMake builds its first test project
      to check that the compiler for a language works.  It should not be
      used to load a file in cases that a normal include() will work.  Use
      it only as a last resort for behavior that cannot be achieved any
      other way.  For example, one may set CMAKE_C_FLAGS_INIT to change the
      default value used to initialize CMAKE_C_FLAGS before it is cached.
      The override file should NOT be used to set anything that could be set
      after languages are enabled, such as variables like
      CMAKE_RUNTIME_OUTPUT_DIRECTORY that affect the placement of binaries.
      Information set in the file will be used for try_compile and try_run
      builds too.
 
  CMAKE_WARN_ON_ABSOLUTE_INSTALL_DESTINATION
      Ask cmake_install.cmake script to warn each time a file with absolute
      INSTALL DESTINATION is encountered.
 
      This variable is used by CMake-generated cmake_install.cmake scripts.
      If ones set this variable to ON while running the script, it may get
      warning messages from the script.
 
------------------------------------------------------------------------------
Variables That Describe the System
 
  APPLE
      True if running on Mac OSX.
 
      Set to true on Mac OSX.
 
  BORLAND
      True if the borland compiler is being used.
 
      This is set to true if the Borland compiler is being used.

      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.

      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_LIBRARY_ARCHITECTURE_REGEX
      Regex matching possible target architecture library directory names.
 
      This is used to detect CMAKE_<lang>_LIBRARY_ARCHITECTURE from the
      implicit linker search path by matching the <arch> name.
 
  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_NAME and
      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.
 
  CYGWIN
      True for cygwin.
 
      Set to true when using CYGWIN.
 
  MSVC
      True when using Microsoft Visual C
 
      Set to true when the compiler is some version of Microsoft Visual C.

  MSVC90
      True when using Microsoft Visual C 9.0
 
      Set to true when the compiler is version 9.0 of Microsoft Visual C.
 
  MSVC_IDE
      True when using the Microsoft Visual C IDE
 
      Set to true when the target platform is the Microsoft Visual C IDE, as
      opposed to the command line compiler.
 
  MSVC_VERSION
      The version of Microsoft Visual C/C++ being used if any.
 
      Known version numbers are:
 
        1200 = VS  6.0
        1300 = VS  7.0
        1310 = VS  7.1
        1400 = VS  8.0
        1500 = VS  9.0

------------------------------------------------------------------------------
Variables common to all CPack generators
 
  CPACK_ABSOLUTE_DESTINATION_FILES
      List of files which have been installed using an ABSOLUTE DESTINATION
      path.
 
      This variable is a Read-Only variable which is set internally by CPack
      during installation and before packaging using
      CMAKE_ABSOLUTE_DESTINATION_FILES defined in cmake_install.cmake
      scripts.  The value can be used within CPack project configuration
      file and/or CPack<GEN>.cmake file of <GEN> generator.
 
  CPACK_BINARY_<GENNAME>
      CPack generated options for binary generators
 
      The CPack.cmake module generates (when CPACK_GENERATOR is not set) a
      set of CMake options (see CMake option command) which may then be used
      to select the CPack generator(s) to be used when launching the package
      target.
 
  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_COMPONENT_INCLUDE_TOPLEVEL_DIRECTORY
      Boolean toggle to include/exclude top level directory (component
      case).
 
      Similar usage as CPACK_INCLUDE_TOPLEVEL_DIRECTORY but for the
      component case.  See CPACK_INCLUDE_TOPLEVEL_DIRECTORY documentation
      for the detail.
 
  CPACK_CREATE_DESKTOP_LINKS
      List of desktop links to create
 
  CPACK_GENERATOR
      List of CPack generators to use
 
      If not specified, CPack will create a set of options
      CPACK_BINARY_<GENNAME> (e.g., CPACK_BINARY_NSIS) allowing the user to
      enable/disable individual generators.  This variable may be used on
      the command line as well as in:
 
          cpack -D CPACK_GENERATOR="ZIP;TGZ" /path/to/build/tree
 
 
  CPACK_INCLUDE_TOPLEVEL_DIRECTORY
      Boolean toggle to include/exclude top level directory.
 
      When preparing a package CPack installs the item under the so-called
      top level directory.  The purpose of is to include (set to 1 or ON or
      TRUE) the top level directory in the package or not (set to 0 or OFF
      or FALSE).
 
      Each CPack generator as a built-in default value for this variable.
      E.g.  Archive generators (ZIP, TGZ, ...) includes the top level
      whereas RPM or DEB don't.  The user may override the default value by
      setting this variable.
 
      There is a similar variable CPACK_COMPONENT_INCLUDE_TOPLEVEL_DIRECTORY
      which may be used to override the behavior for the component packaging
      case which may have different default value for historical (now
      backward compatibility) reason.
 
  CPACK_INSTALLED_DIRECTORIES
      Extra directories to install
 
  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_INSTALL_COMMANDS
      Extra commands to install components
 
  CPACK_INSTALL_SCRIPT
      Extra CMake script provided by the user.
 
      If set this CMake script will be executed by CPack during its local
      [CPack-private] installation which is done right before packaging the
      files.  The script is not called by e.g.: make install.
 
  CPACK_MONOLITHIC_INSTALL
      Disables the component-based installation mechanism.
 
      When set the component specification is ignored and all installed
      items are put in a single "MONOLITHIC" package.  Some CPack generators
      do monolithic packaging by default and may be asked to do component
      packaging by setting CPACK_<GENNAME>_COMPONENT_INSTALL to 1/TRUE.
 
  CPACK_OUTPUT_CONFIG_FILE
      The name of the CPack binary configuration file.
 
      This file is the CPack configuration generated by the CPack module for
      binary installers.  Defaults to CPackConfig.cmake.
 
  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_DIRECTORY
      The directory in which CPack is doing its packaging.
 
      If it is not set then this will default (internally) to the build dir.
      This variable may be defined in CPack config file or from the cpack
      command line option "-B".  If set the command line option override the
      value found in the config file.
 
  CPACK_PACKAGE_EXECUTABLES
      Lists each of the executables and associated text label to be used to
      create Start Menu shortcuts.
 
      For example, setting this to the list ccmake;CMake will create a
      shortcut named "CMake" that will execute the installed executable
      ccmake.  Not all CPack generators use it (at least NSIS and OSXX11
      do).
 
  CPACK_PACKAGE_FILE_NAME
      The name of the package file to generate, not including the extension.
 
      For example, cmake-2.6.1-Linux-i686.  The default value is
 
        ${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}.
 
 
  CPACK_PACKAGE_ICON
      A branding image that will be displayed inside the installer (used by
      GUI installers).
 
  CPACK_PACKAGE_INSTALL_DIRECTORY
      Installation directory on the target system.
 
      This may be used by some CPack generators like NSIS to create an
      installation directory e.g., "CMake 2.5" below the installation
      prefix.  All installed element will be put inside this directory.
 
  CPACK_PACKAGE_INSTALL_REGISTRY_KEY
      Registry key used when installing this project.
 
      This is only used by installer for Windows.
 
 
  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
      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_PACKAGE_VERSION_MAJOR
      Package major Version
 
  CPACK_PACKAGE_VERSION_MINOR
      Package minor Version
 
  CPACK_PACKAGE_VERSION_PATCH
      Package patch Version
 
  CPACK_PACKAGING_INSTALL_PREFIX
      The prefix used in the built package.
 
      Each CPack generator has a default value (like /usr).  This default
      value may be overwritten from the CMakeLists.txt or the cpack command
      line by setting an alternative value.
 
      e.g.  set(CPACK_PACKAGING_INSTALL_PREFIX "/opt")
 
      This is not the same purpose as CMAKE_INSTALL_PREFIX which is used
      when installing from the build tree without building a package.
 
  CPACK_PROJECT_CONFIG_FILE
      CPack-time project CPack configuration file.
 
      This file included at cpack time, once per generator after CPack has
      set CPACK_GENERATOR to the actual generator being used.  It allows
      per-generator setting of CPACK_* variables at cpack time.
 
  CPACK_RESOURCE_FILE_LICENSE
      License to be embedded in the installer
 
      It will typically be displayed to the user by the produced installer
      (often with an explicit "Accept" button, for graphical installers)
      prior to installation.  This license file is NOT added to installed
      file but is used by some CPack generators like NSIS.  If you want to
      install a license file (may be the same as this one) along with your
      project you must add an appropriate CMake INSTALL command in your
      CMakeLists.txt.
 
  CPACK_RESOURCE_FILE_README
      ReadMe file to be embedded in the installer
 
      It typically describes in some detail the purpose of the project
      during the installation.  Not all CPack generators uses this file.
 
  CPACK_RESOURCE_FILE_WELCOME
      Welcome file to be embedded in the installer.
 
      It welcomes users to this installer.  Typically used in the graphical
      installers on Windows and Mac OS X.
 
  CPACK_SET_DESTDIR
      Boolean toggle to make CPack use DESTDIR mechanism when packaging.
 
      DESTDIR means DESTination DIRectory.  It is commonly used by makefile
      users in order to install software at non-default location.  It is a
      basic relocation mechanism that should not be used on Windows (see
      CMAKE_INSTALL_PREFIX documentation).  It is usually invoked like this:
 
        make DESTDIR=/home/john install
 
      which will install the concerned software using the installation
      prefix, e.g.  "/usr/local" pre-pended with the DESTDIR value which
      finally gives "/home/john/usr/local".  When preparing a package, CPack
      first installs the items to be packaged in a local (to the build tree)
      directory by using the same DESTDIR mechanism.  Nevertheless, if
      CPACK_SET_DESTDIR is set then CPack will set DESTDIR before doing the
      local install.  The most noticeable difference is that without
      CPACK_SET_DESTDIR, CPack uses CPACK_PACKAGING_INSTALL_PREFIX as a
      prefix whereas with CPACK_SET_DESTDIR set, CPack will use
      CMAKE_INSTALL_PREFIX as a prefix.
 
      Manually setting CPACK_SET_DESTDIR may help (or simply be necessary)
      if some install rules uses absolute DESTINATION (see CMake INSTALL
      command).  However, starting with CPack/CMake 2.8.3 RPM and DEB
      installers tries to handle DESTDIR automatically so that it is seldom
      necessary for the user to set it.
 
  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_IGNORE_FILES
      Pattern of files in the source tree that won't be packaged when
      building a source package.
 
      This is a list of regular expression patterns (that must be properly
      escaped), e.g., /CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*
 
  CPACK_SOURCE_OUTPUT_CONFIG_FILE
      The name of the CPack source configuration file.
 
      This file is the CPack configuration generated by the CPack module for
      source installers.  Defaults to CPackSourceConfig.cmake.
 
  CPACK_SOURCE_PACKAGE_FILE_NAME
      The name of the source package
 
      For example 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_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).
 
  CPACK_SYSTEM_NAME
      System name, defaults to the value of ${CMAKE_SYSTEM_NAME}.
 
  CPACK_TOPLEVEL_TAG
      Directory for the installed files
 
  CPACK_WARN_ON_ABSOLUTE_INSTALL_DESTINATION
      Ask CPack to warn each time a file with absolute INSTALL DESTINATION
      is encountered.
 
      This variable triggers the definition of
      CMAKE_WARN_ON_ABSOLUTE_INSTALL_DESTINATION when CPack runs
      cmake_install.cmake scripts.
 
------------------------------------------------------------------------------
Variables concerning CPack Components
 
  CPACK_<GENNAME>_COMPONENT_INSTALL
      Enable/Disable component install for CPack generator <GENNAME>.
 
      Each CPack Generator (RPM, DEB, ARCHIVE, NSIS, DMG, etc...) has a
      legacy default behavior.  e.g.  RPM builds monolithic whereas NSIS
      builds component.  One can change the default behavior by setting this
      variable to 0/1 or OFF/ON.
 
  CPACK_COMPONENTS_ALL
      The list of component to install
 
      The default value of this variable is computed by CPack and contains
      all components defined by the project.  The user may set it to only
      include the specified components.
 
  CPACK_COMPONENTS_GROUPING
      Specify how components are grouped for multi-package component-aware
      CPack generators.
 
      Some generators like RPM or ARCHIVE family (TGZ, ZIP, ...) generates
      several packages files when asked for component packaging.  They group
      the component differently depending on the value of this variable:
 
        - ONE_PER_GROUP (default): creates one package file per component group
        - ALL_COMPONENTS_IN_ONE : creates a single package with all (requested) component
        - IGNORE : creates one package per component, i.e. IGNORE component group
 
      One can specify different grouping for different CPack generator by
      using a CPACK_PROJECT_CONFIG_FILE.
 
  CPACK_COMPONENT_<compName>_DEPENDS
      The dependencies (list of components) on which this component depends.
 
  CPACK_COMPONENT_<compName>_DESCRIPTION
      The description of a component
 
  CPACK_COMPONENT_<compName>_DISPLAY_NAME
      The name to be displayed for a component
 
  CPACK_COMPONENT_<compName>_GROUP
      The group of a component
 
  CPACK_COMPONENT_<compName>_REQUIRED
      True is this component is required
 
------------------------------------------------------------------------------
Variables for Languages
 
  CMAKE_<LANG>_ARCHIVE_APPEND
      Rule variable to append to a static archive.
 
      This is a rule variable that tells CMake how to append to a static
      archive.  It is used in place of CMAKE_<LANG>_CREATE_STATIC_LIBRARY on
      some platforms in order to support large object counts.  See also
      CMAKE_<LANG>_ARCHIVE_CREATE and CMAKE_<LANG>_ARCHIVE_FINISH.
 
  CMAKE_<LANG>_ARCHIVE_CREATE
      Rule variable to create a new static archive.
 
      This is a rule variable that tells CMake how to create a static
      archive.  It is used in place of CMAKE_<LANG>_CREATE_STATIC_LIBRARY on
      some platforms in order to support large object counts.  See also
      CMAKE_<LANG>_ARCHIVE_APPEND and CMAKE_<LANG>_ARCHIVE_FINISH.
 
  CMAKE_<LANG>_ARCHIVE_FINISH
      Rule variable to finish an existing static archive.
 
      This is a rule variable that tells CMake how to finish a static
      archive.  It is used in place of CMAKE_<LANG>_CREATE_STATIC_LIBRARY on
      some platforms in order to support large object counts.  See also
      CMAKE_<LANG>_ARCHIVE_CREATE and CMAKE_<LANG>_ARCHIVE_APPEND.
 
  CMAKE_<LANG>_COMPILER

      variable is defined to 1.
 
  CMAKE_<LANG>_COMPILER_VERSION
      Compiler version string.
 
      Compiler version in major[.minor[.patch[.tweak]]] format.  This
      variable is not guaranteed to be defined for all compilers or
      languages.

  CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES
      Directories implicitly searched by the compiler for header files.
 
      CMake does not explicitly specify these directories on compiler
      command lines for language <LANG>.  This prevents system include
      directories from being treated as user include directories on some
      compilers.
 
  CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES
      Implicit linker search path detected for language <LANG>.
 
      Compilers typically pass directories containing language runtime
      libraries and default library search paths when they invoke a linker.
      These paths are implicit linker search directories for the compiler's
      language.  CMake automatically detects these directories for each
      language and reports the results in this variable.
 
  CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES
      Implicit link libraries and flags detected for language <LANG>.
 
      Compilers typically pass language runtime library names and other
      flags when they invoke a linker.  These flags are implicit link
      options for the compiler's language.  CMake automatically detects
      these libraries and flags for each language and reports the results in
      this variable.
 
  CMAKE_<LANG>_LIBRARY_ARCHITECTURE
      Target architecture library directory name detected for <lang>.

      system library search directory such as <prefix>/lib/<arch> this
      variable contains the <arch> name if/as detected by CMake.
 
  CMAKE_<LANG>_LINKER_PREFERENCE
      Preference value for linker language selection.
 
      The "linker language" for executable, shared library, and module
      targets is the language whose compiler will invoke the linker.  The
      LINKER_LANGUAGE target property sets the language explicitly.
      Otherwise, the linker language is that whose linker preference value
      is highest among languages compiled and linked into the target.  See
      also the CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES variable.
 
  CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES
      True if CMAKE_<LANG>_LINKER_PREFERENCE propagates across targets.
 
      This is used when CMake selects a linker language for a target.
      Languages compiled directly into the target are always considered.  A
      language compiled into static libraries linked by the target is
      considered if this variable is true.
 
  CMAKE_<LANG>_LINK_EXECUTABLE
      Rule variable to link and executable.
 
      Rule variable to link and executable for the given language.
 
  CMAKE_<LANG>_OUTPUT_EXTENSION

      An internal variable subject to change.
 
      This is used in determining the platform and is subject to change.
 
  CMAKE_<LANG>_SIZEOF_DATA_PTR
      Size of pointer-to-data types for language <LANG>.
 
      This holds the size (in bytes) of pointer-to-data types in the target
      platform ABI.  It is defined for languages C and CXX (C++).
 
  CMAKE_<LANG>_SOURCE_FILE_EXTENSIONS
      Extensions of source files for the given language.
 
      This is the list of extensions for a given languages source files.
 
  CMAKE_COMPILER_IS_GNU<LANG>
      True if the compiler is GNU.
 
      If the selected <LANG> compiler is the GNU compiler then this is TRUE,
      if not it is FALSE.
 
  CMAKE_Fortran_MODDIR_DEFAULT
      Fortran default module output directory.
 
      Most Fortran compilers write .mod files to the current working
      directory.  For those that do not, this is set to "." and used when
      the Fortran_MODULE_DIRECTORY target property is not set.
 
  CMAKE_Fortran_MODDIR_FLAG
      Fortran flag for module output directory.
 
      This stores the flag needed to pass the value of the
      Fortran_MODULE_DIRECTORY target property to the compiler.
 
  CMAKE_Fortran_MODOUT_FLAG
      Fortran flag to enable module output.
 
      Most Fortran compilers write .mod files out by default.  For others,
      this stores the flag needed to enable module output.
 
  CMAKE_INTERNAL_PLATFORM_ABI
      An internal variable subject to change.
 
      This is used in determining the compiler ABI and is subject to change.
 
  CMAKE_USER_MAKE_RULES_OVERRIDE_<LANG>
      Specify a CMake file that overrides platform information for <LANG>.
 
      This is a language-specific version of CMAKE_USER_MAKE_RULES_OVERRIDE
      loaded only when enabling language <LANG>.

            value if the previous packaging was buggy and/or you want to put here
            a fancy Linux distro specific numbering.
 
 
  CPACK_RPM_PACKAGE_RELOCATABLE
      build a relocatable RPM
 
            Mandatory : NO
            Default  : CPACK_PACKAGE_RELOCATABLE
            If this variable is set to TRUE or ON CPackRPM will try
            to build a relocatable RPM package. A relocatable RPM may
            be installed using rpm --prefix or --relocate in order to
            install it at an alternate place see rpm(8).
            Note that currently this may fail if CPACK_SET_DESTDIR is set to ON.
            If CPACK_SET_DESTDIR is set then you will get a warning message
            but if there is file installed with absolute path you'll get
            unexpected behavior.

  CPACK_RPM_PACKAGE_VERSION
      The RPM package version
 
            Mandatory : YES
            Default  : CPACK_PACKAGE_VERSION
 
 
  CPACK_RPM_POST_INSTALL_SCRIPT_FILE
 
        CPACK_RPM_POST_UNINSTALL_SCRIPT_FILE
            Mandatory : NO
            Default  : -
            May be used to embed a post (un)installation script in the spec file.
            The refered script file(s) will be read and directly
            put after the %post or %postun section
            If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for
            each component can be overridden with
            CPACK_RPM_<COMPONENT>_POST_INSTALL_SCRIPT_FILE and
            CPACK_RPM_<COMPONENT>_POST_UNINSTALL_SCRIPT_FILE
            One may verify which scriptlet has been included with
            rpm -qp --scripts  package.rpm
 
 
  CPACK_RPM_PRE_INSTALL_SCRIPT_FILE
 
        CPACK_RPM_PRE_UNINSTALL_SCRIPT_FILE
            Mandatory : NO
            Default  : -
            May be used to embed a pre (un)installation script in the spec file.
            The refered script file(s) will be read and directly
            put after the %pre or %preun section
            If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for
            each component can be overridden with
            CPACK_RPM_<COMPONENT>_PRE_INSTALL_SCRIPT_FILE and
            CPACK_RPM_<COMPONENT>_PRE_UNINSTALL_SCRIPT_FILE
            One may verify which scriptlet has been included with
            rpm -qp --scripts  package.rpm
 
 
  CPACK_RPM_SPEC_INSTALL_POST
      [deprecated]
 
            Mandatory : NO
            Default  : -
            This way of specifying post-install script is deprecated use
            CPACK_RPM_POST_INSTALL_SCRIPT_FILE
            May be used to set an RPM post-install command inside the spec file.
            For example setting it to "/bin/true" may be used to prevent
            rpmbuild to strip binaries.
 
 
  CPACK_RPM_SPEC_MORE_DEFINE
      RPM extended spec definitions lines
 
            Mandatory : NO
            Default  : -
            May be used to add any %define lines to the generated spec file.
 
 
  CPACK_RPM_USER_BINARY_SPECFILE
      A user provided spec file
 
            Mandatory : NO
            Default  : -
            May be set by the user in order to specify a USER binary spec file
            to be used by CPackRPM instead of generating the file.
            The specified file will be processed by configure_file( @ONLY).
 
 
  CPACK_RPM_USER_FILELIST
 
        CPACK_RPM_<COMPONENT>_USER_FILELIST
            Mandatory : NO
            Default  : -
            May be used to explicitly specify %(<directive>) file line
            in the spec file. Like %config(noreplace) or any other directive
            that be found in the %files section. Since CPackRPM is generating
            the list of files (and directories) the user specified files of
            the CPACK_RPM_<COMPONENT>_USER_FILELIST list will be removed from the generated list.
 
 
------------------------------------------------------------------------------
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_AUTOMOC
      Whether to handle moc automatically for Qt targets.
 
      This variable is used to initialize the AUTOMOC property on all the
      targets.  See that target property for additional information.
 
  CMAKE_AUTOMOC_MOC_OPTIONS
      Additional options for moc when using automoc (see CMAKE_AUTOMOC).
 
      This variable is used to initialize the AUTOMOC_MOC_OPTIONS 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_FORMAT
      Set to FIXED or FREE to indicate the Fortran source layout.
 
      This variable is used to initialize the Fortran_FORMAT property on all
      the targets.  See that target property for additional information.
 
  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_GNUtoMS
      Convert GNU import libraries (.dll.a) to MS format (.lib).
 
      This variable is used to initialize the GNUtoMS property on targets
      when they are created.  See that target property for additional
      information.
 
  CMAKE_INCLUDE_CURRENT_DIR
      Automatically add the current source- and build directories to the
      include path.
 
      If this variable is enabled, CMake automatically adds in each
      directory ${CMAKE_CURRENT_SOURCE_DIR} and ${CMAKE_CURRENT_BINARY_DIR}
      to the include path for this directory.  These additional include
      directories do not propagate down to subdirectories.  This is useful
      mainly for out-of-source builds, where files generated into the build
      tree are included by files located in the source tree.
 
      By default CMAKE_INCLUDE_CURRENT_DIR is OFF.
 
  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_INTERFACE_LIBRARIES
      Default value for LINK_INTERFACE_LIBRARIES of targets.
 
      This variable is used to initialize the LINK_INTERFACE_LIBRARIES
      property on all the targets.  See that target property for additional
      information.
 
  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_MACOSX_BUNDLE
      Default value for MACOSX_BUNDLE of targets.
 
      This variable is used to initialize the MACOSX_BUNDLE property on all
      the targets.  See that target property for additional information.
 
  CMAKE_NO_BUILTIN_CHRPATH
      Do not use the builtin ELF editor to fix RPATHs on installation.
 
      When an ELF binary needs to have a different RPATH after installation
      than it does in the build tree, CMake uses a builtin editor to change
      the RPATH in the installed copy.  If this variable is set to true then
      CMake will relink the binary before installation instead of using its
      builtin editor.
 
  CMAKE_PDB_OUTPUT_DIRECTORY
      Where to put all the MS debug symbol files.
 
      This variable is used to initialize the PDB_OUTPUT_DIRECTORY property
      on all the targets.  See that target property for additional
      information.
 
  CMAKE_POSITION_INDEPENDENT_CODE
      Default value for POSITION_INDEPENDENT_CODE of targets.
 
      This variable is used to initialize the POSITION_INDEPENDENT_CODE
      property on all the targets.  See that target property for additional
      information.
 
  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_SKIP_INSTALL_RPATH
      Do not include RPATHs in the install 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 installed without RPATH, even if RPATH is enabled when
      building.  This can be useful for example to allow running tests from
      the build directory with RPATH enabled before the installation step.
      To omit RPATH in both the build and install steps, use
      CMAKE_SKIP_RPATH instead.
 
  CMAKE_TRY_COMPILE_CONFIGURATION
      Build configuration used for try_compile and try_run projects.
 
      Projects built by try_compile and try_run are built synchronously
      during the CMake configuration step.  Therefore a specific build
      configuration must be chosen even if the generated build system
      supports multiple configurations.
 
  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.
 
  CMAKE_WIN32_EXECUTABLE
      Default value for WIN32_EXECUTABLE of targets.
 
      This variable is used to initialize the WIN32_EXECUTABLE property on
      all the targets.  See that target property for additional information.
 
  EXECUTABLE_OUTPUT_PATH
      Old executable location variable.
 
      The target property RUNTIME_OUTPUT_DIRECTORY supercedes this variable
      for a target if it is set.  Executable targets are otherwise placed in
      this directory.
 
  LIBRARY_OUTPUT_PATH
      Old library location variable.
 
      The target properties ARCHIVE_OUTPUT_DIRECTORY,
      LIBRARY_OUTPUT_DIRECTORY, and RUNTIME_OUTPUT_DIRECTORY supercede this
      variable for a target if they are set.  Library targets are otherwise
      placed in this directory.
 
------------------------------------------------------------------------------
Variables that Provide Information
 
  CMAKE_AR
      Name of archiving tool for static libraries.
 
      This specifies name of the program that creates archive or static
      libraries.
 
  CMAKE_ARGC
      Number of command line arguments passed to CMake in script mode.
 
      When run in -P script mode, CMake sets this variable to the number of
      command line arguments.  See also CMAKE_ARGV0, 1, 2 ...
 
  CMAKE_ARGV0
      Command line argument passed to CMake in script mode.
 
      When run in -P script mode, CMake sets this variable to the first
      command line argument.  It then also sets CMAKE_ARGV1, CMAKE_ARGV2,
      ...  and so on, up to the number of command line arguments given.  See
      also CMAKE_ARGC.
 
  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 actual 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_BUILD_TOOL 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_PATCH_VERSION
      Patch version of CMake used to create the CMakeCache.txt file
 
      This is stores the patch 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 reference to per-configuration output subdirectory.
 
      For native build systems supporting multiple configurations in the
      build tree (such as Visual Studio and Xcode), the value is a reference
      to a build-time variable specifying the name of the per-configuration
      output subdirectory.  On Makefile generators this evaluates to "."
      because there is only one configuration in a build tree.  Example
      values:
 
        $(IntDir)        = Visual Studio 6
        $(OutDir)        = Visual Studio 7, 8, 9
        $(Configuration) = Visual Studio 10
        $(CONFIGURATION) = Xcode
        .                = Make-based tools
 
      Since these values are evaluated by the native build system, this
      variable is suitable only for use in command lines that will be
      evaluated at build time.  Example of intended usage:
 
        add_executable(mytool mytool.c)
        add_custom_command(
          OUTPUT out.txt
          COMMAND ${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool
                  ${CMAKE_CURRENT_SOURCE_DIR}/in.txt out.txt
          DEPENDS mytool in.txt
          )
        add_custom_target(drive ALL DEPENDS out.txt)
 
      Note that CMAKE_CFG_INTDIR is no longer necessary for this purpose but
      has been left for compatibility with existing projects.  Instead
      add_custom_command() recognizes executable target names in its COMMAND
      option, so "${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool"
      can be replaced by just "mytool".
 
      This variable is read-only.  Setting it is undefined behavior.  In
      multi-configuration build systems the value of this variable is passed
      as the value of preprocessor symbol "CMAKE_INTDIR" to the compilation
      of all source files.
 
  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_DIR
      Full directory of the listfile currently being processed.
 
      As CMake processes the listfiles in your project this variable will
      always be set to the directory where the listfile which is currently
      being processed (CMAKE_CURRENT_LIST_FILE) is located.  The value has
      dynamic scope.  When CMake starts processing commands in a source file
      it sets this variable to the directory where this file is located.
      When CMake finishes processing commands from the file it restores the
      previous value.  Therefore the value of the variable inside a macro or
      function is the directory of the file invoking the bottom-most entry
      on the call stack, not the directory of the file containing the macro
      or function definition.
 
      See also CMAKE_CURRENT_LIST_FILE.
 
  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.  The value has
      dynamic scope.  When CMake starts processing commands in a source file
      it sets this variable to the location of the file.  When CMake
      finishes processing commands from the file it restores the previous
      value.  Therefore the value of the variable inside a macro or function
      is the file invoking the bottom-most entry on the call stack, not the
      file containing the macro or function definition.
 
      See also CMAKE_PARENT_LIST_FILE.
 
  CMAKE_CURRENT_LIST_LINE
      The line number of the current file being processed.
 
      This is the line number of the file currently being processed by
      cmake.
 
  CMAKE_CURRENT_SOURCE_DIR
      The path to the source directory currently being processed.
 
      This the full path to the source directory that is currently being
      processed by cmake.
 
  CMAKE_DL_LIBS
      Name of library containing dlopen and dlcose.
 
      The name of the library that has dlopen and dlclose in it, usually
      -ldl on most UNIX machines.
 
  CMAKE_EDIT_COMMAND
      Full path to cmake-gui or ccmake.
 
      This is the full path to the CMake executable that can graphically
      edit the cache.  For example, cmake-gui, ccmake, or cmake -i.

  CMAKE_EXTRA_GENERATOR
      The extra generator used to build the project.
 
      When using the Eclipse, CodeBlocks or KDevelop generators, CMake
      generates Makefiles (CMAKE_GENERATOR) and additionally project files
      for the respective IDE.  This IDE project file generator is stored in
      CMAKE_EXTRA_GENERATOR (e.g.  "Eclipse CDT4").
 
  CMAKE_EXTRA_SHARED_LIBRARY_SUFFIXES
      Additional suffixes for shared libraries.
 
      Extensions for shared libraries other than that specified by
      CMAKE_SHARED_LIBRARY_SUFFIX, if any.  CMake uses this to recognize
      external shared library files during analysis of libraries linked by a
      target.
 
  CMAKE_GENERATOR
      The generator used to build the project.
 
      The name of the generator that is being used to generate the build
      files.  (e.g.  "Unix Makefiles", "Visual Studio 6", etc.)

      This specifies the minor version of the CMake executable being run.
 
  CMAKE_PARENT_LIST_FILE
      Full path to the parent listfile of the one currently being processed.
 
      As CMake processes the listfiles in your project this variable will
      always be set to the listfile that included or somehow invoked the one
      currently being processed.  See also CMAKE_CURRENT_LIST_FILE.

  CMAKE_SCRIPT_MODE_FILE
      Full path to the -P script file currently being processed.
 
      When run in -P script mode, CMake sets this variable to the full path
      of the script file.  When run to configure a CMakeLists.txt file, this
      variable is not set.
 
  CMAKE_SHARED_LIBRARY_PREFIX
      The prefix for shared libraries that you link to.
 
      The prefix to use for the name of a shared library, lib on UNIX.
 
      CMAKE_SHARED_LIBRARY_PREFIX_<LANG> overrides this for language <LANG>.
 
  CMAKE_SHARED_LIBRARY_SUFFIX
      The suffix for shared libraries that you link to.
 
      The suffix to use for the end of a shared library, .dll on Windows.
 
      CMAKE_SHARED_LIBRARY_SUFFIX_<LANG> overrides this for language <LANG>.
 
  CMAKE_SHARED_MODULE_PREFIX
      The prefix for loadable modules that you link to.
 
      The prefix to use for the name of a loadable module on this platform.
 
      CMAKE_SHARED_MODULE_PREFIX_<LANG> overrides this for language <LANG>.
 
  CMAKE_SHARED_MODULE_SUFFIX
      The suffix for shared libraries that you link to.
 
      The suffix to use for the end of a loadable module on this platform
 
      CMAKE_SHARED_MODULE_SUFFIX_<LANG> overrides this for language <LANG>.
 
  CMAKE_SIZEOF_VOID_P
      Size of a void pointer.
 
      This is set to the size of a pointer on the machine, and is determined
      by a try compile.  If a 64 bit size is found, then the library search
      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 default is to add rpath information if the
      platform supports it.  This allows for easy running from the build
      tree.  To omit RPATH in the install step, but not the build step, use
      CMAKE_SKIP_INSTALL_RPATH instead.
 
  CMAKE_SOURCE_DIR
      The path to the top level of the source tree.
 
      This is the full path to the top level of the current CMake source
      tree.  For an in-source build, this would be the same as
      CMAKE_BINARY_DIR.
 
  CMAKE_STANDARD_LIBRARIES
      Libraries linked into every executable and shared library.
 
      This is the list of libraries that are linked into all executables and
      libraries.
 
  CMAKE_STATIC_LIBRARY_PREFIX
      The prefix for static libraries that you link to.
 
      The prefix to use for the name of a static library, lib on UNIX.
 
      CMAKE_STATIC_LIBRARY_PREFIX_<LANG> overrides this for language <LANG>.
 
  CMAKE_STATIC_LIBRARY_SUFFIX
      The suffix for static libraries that you link to.
 
      The suffix to use for the end of a static library, .lib on Windows.
 
      CMAKE_STATIC_LIBRARY_SUFFIX_<LANG> overrides this for language <LANG>.
 
  CMAKE_TWEAK_VERSION
      The tweak version of cmake (i.e.  the 1 in X.X.X.1).
 
      This specifies the tweak version of the CMake executable being run.
      Releases use tweak < 20000000 and development versions use the date
      format CCYYMMDD for the tweak level.
 
  CMAKE_VERBOSE_MAKEFILE
      Create verbose makefiles if on.
 
      This variable defaults to false.  You can set this variable to true to
      make CMake produce verbose makefiles that show each command line as it
      is used.
 
  CMAKE_VERSION
      The full version of cmake in major.minor.patch[.tweak[-id]] format.
 
      This specifies the full version of the CMake executable being run.
      This variable is defined by versions 2.6.3 and higher.  See variables
      CMAKE_MAJOR_VERSION, CMAKE_MINOR_VERSION, CMAKE_PATCH_VERSION, and
      CMAKE_TWEAK_VERSION for individual version components.  The [-id]
      component appears in non-release versions and may be arbitrary text.
 
  CMAKE_VS_PLATFORM_TOOLSET
      Visual Studio Platform Toolset name.
 
      VS 10 and above use MSBuild under the hood and support multiple
      compiler toolchains.  CMake may specify a toolset explicitly, such as
      "v110" for VS 11 or "Windows7.1SDK" for 64-bit support in VS 10
      Express.  CMake provides the name of the chosen toolset in this
      variable.
 
  PROJECT_BINARY_DIR
      Full path to build directory for project.
 
      This is the binary directory of the most recent PROJECT command.
 
  PROJECT_NAME
      Name of the project given to the project command.
 
      This is the name given to the most recent PROJECT command.
 
  PROJECT_SOURCE_DIR
      Top level source directory for the current project.
 
      This is the source directory of the most recent PROJECT command.
 
  [Project name]_BINARY_DIR
      Top level binary directory for the named project.
 
      A variable is created with the name used in the PROJECT command, and
      is the binary directory for the project.  This can be useful when
      SUBDIR is used to connect several projects.
 
  [Project name]_SOURCE_DIR
      Top level source directory for the named project.
 
      A variable is created with the name used in the PROJECT command, and
      is the source directory for the project.  This can be useful when
      add_subdirectory is used to connect several projects.
