cpack version 2.8.9
------------------------------------------------------------------------------
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
          inconsitent sets of components.
 
     
 
          GROUP names the component group of which this component is a
          part. If not provided, the component will be a standalone
          component, not part of any component group. Component groups are
          described with the cpack_add_component_group command, detailed
          below.
 
     
 
          INSTALL_TYPES lists the installation types of which this component
          is a part. When one of these installations types is selected, this
          component will automatically be selected. Installation types are
          described with the cpack_add_install_type command, detailed below.
 
     
 
          DOWNLOADED indicates that this component should be downloaded
          on-the-fly by the installer, rather than packaged in with the
          installer itself. For more information, see the cpack_configure_downloads
          command.
 
     
 
          ARCHIVE_FILE provides a name for the archive file created by CPack
          to be used for downloaded components. If not supplied, CPack will
          create a file with some name based on CPACK_PACKAGE_FILE_NAME and
          the name of the component. See cpack_configure_downloads for more
          information.
 
 
  cpack_add_component_group
      Describes a group of related CPack installation components.
 
            cpack_add_component_group(groupname
                                    [DISPLAY_NAME name]
                                    [DESCRIPTION description]
                                    [PARENT_GROUP parent]
                                    [EXPANDED]
                                    [BOLD_TITLE])
 
     
 
          The cpack_add_component_group describes a group of installation
          components, which will be placed together within the listing of
          options. Typically, component groups allow the user to
          select/deselect all of the components within a single group via a
          single group-level option. Use component groups to reduce the
          complexity of installers with many options. groupname is an
          arbitrary name used to identify the group in the GROUP argument of
          the cpack_add_component command, which is used to place a
          component in a group. The name of the group must not conflict with
          the name of any component.
 
     
 
          DISPLAY_NAME is the displayed name of the component group, used in
          graphical installers to display the component group name. This
          value can be any string.
 
     
 
          DESCRIPTION is an extended description of the component group,
          used in graphical installers to give the user additional
          information about the components within that group. Descriptions
          can span multiple lines using "\n" as the line
          separator. Typically, these descriptions should be no more than a
          few lines long.
 
     
 
          PARENT_GROUP, if supplied, names the parent group of this group.
          Parent groups are used to establish a hierarchy of groups,
          providing an arbitrary hierarchy of groups.
 
     
 
          EXPANDED indicates that, by default, the group should show up as
          "expanded", so that the user immediately sees all of the
          components within the group. Otherwise, the group will initially
          show up as a single entry.
 
     
 
          BOLD_TITLE indicates that the group title should appear in bold,
          to call the user's attention to the group.
 
 
  cpack_add_install_type
      Add a new installation type containing a set of predefined component
      selections to the graphical installer.
 
            cpack_add_install_type(typename
                                  [DISPLAY_NAME name])
 
     
 
          The cpack_add_install_type command identifies a set of preselected
          components that represents a common use case for an
          application. For example, a "Developer" install type might include
          an application along with its header and library files, while an
          "End user" install type might just include the application's
          executable. Each component identifies itself with one or more
          install types via the INSTALL_TYPES argument to
          cpack_add_component.
 
     
 
          DISPLAY_NAME is the displayed name of the install type, which will
          typically show up in a drop-down box within a graphical
          installer. This value can be any string.
 
 
  cpack_configure_downloads
      Configure CPack to download selected components on-the-fly as part of
      the installation process.
 
            cpack_configure_downloads(site
                                      [UPLOAD_DIRECTORY dirname]
                                      [ALL]
                                      [ADD_REMOVE|NO_ADD_REMOVE])
 
     
 
          The cpack_configure_downloads command configures installation-time
          downloads of selected components. For each downloadable component,
          CPack will create an archive containing the contents of that
          component, which should be uploaded to the given site. When the
          user selects that component for installation, the installer will
          download and extract the component in place. This feature is
          useful for creating small installers that only download the
          requested components, saving bandwidth. Additionally, the
          installers are small enough that they will be installed as part of
          the normal installation process, and the "Change" button in
          Windows Add/Remove Programs control panel will allow one to add or
          remove parts of the application after the original
          installation. On Windows, the downloaded-components functionality
          requires the ZipDLL plug-in for NSIS, available at:
 
     
 
            http://nsis.sourceforge.net/ZipDLL_plug-in
 
     
 
          On Mac OS X, installers that download components on-the-fly can
          only be built and installed on system using Mac OS X 10.5 or
          later.
 
     
 
          The site argument is a URL where the archives for downloadable
          components will reside, e.g., http://www.cmake.org/files/2.6.1/installer/
          All of the archives produced by CPack should be uploaded to that location.
 
     
 
          UPLOAD_DIRECTORY is the local directory where CPack will create the
          various archives for each of the components. The contents of this
          directory should be uploaded to a location accessible by the URL given
          in the site argument. If omitted, CPack will use the directory
          CPackUploads inside the CMake binary directory to store the generated
          archives.
 
     
 
          The ALL flag indicates that all components be downloaded. Otherwise, only
          those components explicitly marked as DOWNLOADED or that have a specified
          ARCHIVE_FILE will be downloaded. Additionally, the ALL option implies
          ADD_REMOVE (unless NO_ADD_REMOVE is specified).
 
     
 
          ADD_REMOVE indicates that CPack should install a copy of the installer
          that can be called from Windows' Add/Remove Programs dialog (via the
          "Modify" button) to change the set of installed components. NO_ADD_REMOVE
          turns off this behavior. This option is ignored on Mac OS X.
 
 
  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.
 
        elseif(expression)

  execute_process
      Execute one or more child processes.
 
        execute_process(COMMAND <cmd1> [args1...]]
                        [COMMAND <cmd2> [args2...] [...]]
                        [WORKING_DIRECTORY <directory>]
                        [TIMEOUT <seconds>]
                        [RESULT_VARIABLE <variable>]
                        [OUTPUT_VARIABLE <variable>]
                        [ERROR_VARIABLE <variable>]
                        [INPUT_FILE <file>]
                        [OUTPUT_FILE <file>]
                        [ERROR_FILE <file>]
                        [OUTPUT_QUIET]
                        [ERROR_QUIET]
                        [OUTPUT_STRIP_TRAILING_WHITESPACE]
                        [ERROR_STRIP_TRAILING_WHITESPACE])
 
      Runs the given sequence of one or more commands with the standard
      output of each process piped to the standard input of the next.  A
      single standard error pipe is used for all processes.  If
      WORKING_DIRECTORY is given the named directory will be set as the
      current working directory of the child processes.  If TIMEOUT is given
      the child processes will be terminated if they do not finish in the
      specified number of seconds (fractions are allowed).  If
      RESULT_VARIABLE is given the variable will be set to contain the
      result of running the processes.  This will be an integer return code
      from the last child or a string describing an error condition.  If
      OUTPUT_VARIABLE or ERROR_VARIABLE are given the variable named will be
      set with the contents of the standard output and standard error pipes
      respectively.  If the same variable is named for both pipes their
      output will be merged in the order produced.  If INPUT_FILE,
      OUTPUT_FILE, or ERROR_FILE is given the file named will be attached to
      the standard input of the first process, standard output of the last
      process, or standard error of all processes respectively.  If
      OUTPUT_QUIET or ERROR_QUIET is given then the standard output or
      standard error results will be quietly ignored.  If more than one
      OUTPUT_* or ERROR_* option is given for the same pipe the precedence
      is not specified.  If no OUTPUT_* or ERROR_* options are given the
      output will be shared with the corresponding pipes of the CMake
      process itself.
 
      The execute_process command is a newer more powerful version of
      exec_program, but the old command has been kept for compatibility.
 
  file

      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_MD5 sum is specified, the operation will verify that the
      downloaded file's actual md5 sum matches the expected value.  If it
      does not match, the operation fails with an error.  If SHOW_PROGRESS
      is specified, progress information will be printed as status messages
      until the operation is complete.
 
      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

          PATH
          LIB
 
      5.  Search cmake variables defined in the Platform files for the

      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

          "ONLY"  - Only try to find frameworks.
          "NEVER" - Never try to find frameworks.
 
      On Darwin or systems supporting OS X Application Bundles, the cmake
      variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
      following:
 
          "FIRST"  - Try to find application bundles before standard
                    programs. This is the default on Darwin.
          "LAST"  - Try to find application bundles after standard
                    programs.
          "ONLY"  - Only try to find application bundles.
          "NEVER" - Never try to find application bundles.
 
      The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
      directories to be prepended to all other search directories.  This
      effectively "re-roots" the entire search under given locations.  By
      default it is empty.  It is especially useful when cross-compiling to
      point to the root directory of the target environment and CMake will
      search there too.  By default at first the directories listed in
      CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
      searched.  The default behavior can be adjusted by setting
      CMAKE_FIND_ROOT_PATH_MODE_LIBRARY.  This behavior can be manually
      overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
      the search order will be as described above.  If
      NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
      used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
      directories will be searched.
 
      The default search order is designed to be most-specific to
      least-specific for common use cases.  Projects may override the order
      by simply calling the command multiple times and using the NO_*
      options:
 
          find_library(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_library(<VAR> NAMES name)
 
      Once one of the calls succeeds the result variable will be set and
      stored in the cache so that no call will search again.
 
      If the library found is a framework, then VAR will be set to the full
      path to the framework <fullPath>/A.framework.  When a full path to a
      framework is used as a library, CMake will use a -framework A, and a
      -F<fullPath> to link the framework to the target.
 
      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, "", 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(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>

        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
          -        Matches any character in range on either side of a dash
          *        Matches preceding pattern zero or more times
          +        Matches preceding pattern one or more times
          ?        Matches preceding pattern zero or once only
          |        Matches a pattern on either side of the |
          ()        Saves a matched subexpression, which can be referenced
                    in the REGEX REPLACE operation. Additionally it is saved
                    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).
 
      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.
 
  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>)?" or
      "(IMPLIB_)?(PREFIX|SUFFIX)".  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>)?" or
      "(IMPLIB_)?(PREFIX|SUFFIX)".  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.
 
  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.
 
  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
