       cmake-properties - CMake Properties Reference

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.

   AUTOGEN_TARGETS_FOLDER
       Name of FOLDER for *_automoc targets that are added automatically by CMake for targets for
       which AUTOMOC is enabled.

       If not set, CMake uses the FOLDER property of the parent target as  a  default  value  for
       this  property.  See also the documentation for the FOLDER target property and the AUTOMOC
       target property.

   AUTOMOC_TARGETS_FOLDER
       Name of FOLDER for *_automoc targets that are added automatically by CMake for targets for
       which AUTOMOC is enabled.

       This property is obsolete.  Use AUTOGEN_TARGETS_FOLDER instead.

       If  not  set,  CMake  uses the FOLDER property of the parent target as a default value for
       this property.  See also the documentation for the FOLDER target property and the  AUTOMOC
       target property.

   CMAKE_C_KNOWN_FEATURES
       List of C features known to this version of CMake.

       The  features  listed  in  this  global  property  may  be  known to be available to the C

       cxx_template_template_parameters
              Template template parameters, as defined in ISO/IEC 14882:1998.

   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.

   JOB_POOLS
       Ninja only: List of available pools.

       A pool is a named integer property and defines the maximum number of concurrent jobs which
       can   be  started  by  a  rule  assigned  to  the  pool.   The  JOB_POOLS  property  is  a
       semicolon-separated list of pairs using the syntax NAME=integer (without a space after the
       equality sign).

       For instance:

          set_property(GLOBAL PROPERTY JOB_POOLS two_jobs=2 ten_jobs=10)

       Defined   pools   could   be   used   globally   by   setting  CMAKE_JOB_POOL_COMPILE  and
       CMAKE_JOB_POOL_LINK or per target by setting the target  properties  JOB_POOL_COMPILE  and
       JOB_POOL_LINK.

       Build  targets  provided  by  CMake that are meant for individual interactive use, such as
       install, are placed in the console pool automatically.

   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.

   ECLIPSE_EXTRA_NATURES
       List of natures to add to the generated Eclipse project file.

       Eclipse projects specify language plugins by using natures. This property should be set to
       the unique identifier for a nature (which looks like a Java package name).

   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  and  the  Ninja  generator  prefix  compiler commands with the given
       launcher command line.  This is intended to allow launchers to  intercept  build  problems
       with  high  granularity.   Other  generators ignore this property because their underlying
       build systems provide no hook to wrap individual commands with a launcher.

   RULE_LAUNCH_CUSTOM
       Specify a launcher for custom rules.

       Makefile Generators and the Ninja generator prefix custom commands with the given launcher
       command  line.   This is intended to allow launchers to intercept build problems with high
       granularity.  Other generators ignore this property because their underlying build systems
       provide no hook to wrap individual commands with a launcher.

   RULE_LAUNCH_LINK
       Specify a launcher for link rules.

       Makefile  Generators  and  the  Ninja  generator prefix link and archive commands with the
       given launcher command line.  This is intended  to  allow  launchers  to  intercept  build
       problems  with  high  granularity.   Other  generators  ignore this property because their
       underlying build systems provide no hook to wrap individual commands with a launcher.

   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_MESSAGES
       Specify whether to report the completion of each target.

       This property  specifies  whether  Makefile  Generators  should  add  a  progress  message
       describing that each target has been completed.  If the property is not set the default is
       ON.  Set the property to OFF to disable target completion messages.

       This option is intended to reduce build output when little or no work needs to be done  to
       bring the build tree up to date.

       If  a  CMAKE_TARGET_MESSAGES  cache  entry  exists its value initializes the value of this
       property.

       Non-Makefile generators currently ignore this property.

       See the counterpart  property  RULE_MESSAGES  to  disable  everything  except  for  target
       completion messages.

   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.

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
       Set  to  true to tell Makefile Generators not to remove the outputs of custom commands for
       this directory during the make clean operation.   This  is  ignored  on  other  generators
       because it is not possible to implement.

   CMAKE_CONFIGURE_DEPENDS
       Tell  CMake  about additional input files to the configuration process.  If any named file
       is modified the build system will re-run CMake to re-configure the file and  generate  the
       build system again.

       Specify  files  as a semicolon-separated list of paths.  Relative paths are interpreted as
       relative to the current source directory.

   COMPILE_DEFINITIONS
       Preprocessor definitions for compiling a directory's sources.

       This property specifies the list of options given so far to the add_definitions() command.

       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  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 7.0 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.

       Contents of COMPILE_DEFINITIONS may use "generator expressions" with  the  syntax  $<...>.
       See   the  cmake-generator-expressions(7)  manual  for  available  expressions.   See  the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

       The  corresponding  COMPILE_DEFINITIONS_<CONFIG>  property   may   be   set   to   specify
       per-configuration  definitions.   Generator  expressions  should  be  preferred instead of
       setting the alternative property.

   COMPILE_OPTIONS
       List of options to pass to the compiler.

       This property holds a ;-list of options given so far to the add_compile_options() command.

       This property is used to initialize the COMPILE_OPTIONS target property when a  target  is
       created, which is used by the generators to set the options for the compiler.

       Contents  of  COMPILE_OPTIONS may use "generator expressions" with the syntax $<...>.  See
       the  cmake-generator-expressions(7)   manual   for   available   expressions.    See   the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   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  directory
       property instead.

       This built-in read-only property does not exist if policy CMP0059 is set to NEW.

   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 is used to populate the INCLUDE_DIRECTORIES target property, which  is  used
       by the generators to set the include directories for the compiler.

       In  addition  to  accepting  values  from  that command, values may be set directly on any
       directory using the set_property() command.  A directory gets its initial value  from  its
       parent  directory  if  it  has  one.   The  intial value of the INCLUDE_DIRECTORIES target
       property comes from the value of this property.  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.

       Contents of INCLUDE_DIRECTORIES may use "generator expressions" with  the  syntax  $<...>.
       See   the  cmake-generator-expressions(7)  manual  for  available  expressions.   See  the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   INCLUDE_REGULAR_EXPRESSION
       Include file scanning regular expression.

       This property specifies the regular expression used during dependency  scanning  to  match
       include files that should be followed.  See the include_regular_expression() command for a
       high-level interface to set this property.

   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.

   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.

   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.

   VS_GLOBAL_SECTION_POST_<section>
       Specify a postSolution global section in Visual Studio.

       Setting a property like this generates an entry of the  following  form  in  the  solution
       file:

          GlobalSection(<section>) = postSolution
            <contents based on property value>
          EndGlobalSection

       The property must be set to a semicolon-separated list of key=value pairs.  Each such pair
       will be transformed into an entry in the solution global section.  Whitespace  around  key
       and value is ignored.  List elements which do not contain an equal sign are skipped.

       This property only works for Visual Studio 7 and above; it is ignored on other generators.
       The property only applies  when  set  on  a  directory  whose  CMakeLists.txt  contains  a
       project() command.

       Note    that    CMake    generates    postSolution   sections   ExtensibilityGlobals   and
       ExtensibilityAddIns by default.  If you set the corresponding property, it  will  override
       the  default  section.   For  example, setting VS_GLOBAL_SECTION_POST_ExtensibilityGlobals
       will override the default contents of  the  ExtensibilityGlobals  section,  while  keeping
       ExtensibilityAddIns on its default.

   VS_GLOBAL_SECTION_PRE_<section>
       Specify a preSolution global section in Visual Studio.

       Setting  a  property  like  this  generates an entry of the following form in the solution
       file:

          GlobalSection(<section>) = preSolution
            <contents based on property value>
          EndGlobalSection

       The property must be set to a semicolon-separated list of key=value pairs.  Each such pair
       will  be  transformed into an entry in the solution global section.  Whitespace around key
       and value is ignored.  List elements which do not contain an equal sign are skipped.

       This property only works for Visual Studio 7 and above; it is ignored on other generators.
       The  property  only  applies  when  set  on  a  directory  whose CMakeLists.txt contains a
       project() command.

       compiler  processes  (e.g.  4).   This  property  is  initialized  by  the  value  of  the
       CMAKE_ANDROID_PROCESS_MAX variable if it is set when a target is created.

   ANDROID_PROGUARD
       When  this property is set to true that enables the ProGuard tool to shrink, optimize, and
       obfuscate the code by removing unused code and renaming classes, fields, and methods  with
       semantically   obscure   names.   This  property  is  initialized  by  the  value  of  the
       CMAKE_ANDROID_PROGUARD variable if it is set when a target is created.

   ANDROID_PROGUARD_CONFIG_PATH
       Set the Android property that specifies the location of the ProGuard  config  file.  Leave
       empty  to  use the default one.  This a string property that contains the path to ProGuard

       stlport_shared e.g. "STLport Shared" This property is initialized  by  the  value  of  the
       variable:CMAKE_ANDROID_STL_TYPE variable 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 the ARCHIVE_OUTPUT_DIRECTORY target property, 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
       CMAKE_ARCHIVE_OUTPUT_DIRECTORY_<CONFIG> variable if it is set when a target is created.

       Contents of ARCHIVE_OUTPUT_DIRECTORY_<CONFIG> may use generator expressions.

   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.
       The  property  value  may  use generator expressions.  Multi-configuration generators (VS,
       Xcode) append a  per-configuration  subdirectory  to  the  specified  directory  unless  a
       generator expression is used.

       This  property  is initialized by the value of the variable CMAKE_ARCHIVE_OUTPUT_DIRECTORY
       if it is set when a target is created.

       See also the ARCHIVE_OUTPUT_DIRECTORY_<CONFIG> target property.

   ARCHIVE_OUTPUT_NAME_<CONFIG>
       Per-configuration output name for ARCHIVE target files.

       This is the configuration-specific version of the ARCHIVE_OUTPUT_NAME target property.

   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.

       See also the ARCHIVE_OUTPUT_NAME_<CONFIG> target property.

   AUTOGEN_TARGET_DEPENDS
       Target dependencies of the corresponding _automoc target.

       Targets  which  have their AUTOMOC target ON have a corresponding _automoc target which is
       used to  autogenerate  generate  moc  files.   As  this  _automoc  target  is  created  at
       generate-time,  it  is not possible to define dependencies of it, such as to create inputs
       for the moc executable.

       The AUTOGEN_TARGET_DEPENDS target property can be set instead to a  list  of  dependencies
       for the _automoc target.  The buildsystem will be generated to depend on its contents.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   AUTOMOC_MOC_OPTIONS
       Additional options for moc when using AUTOMOC

       This  property  is only used if the AUTOMOC property is ON 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.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   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() or QT5_WRAP_CPP() macro.
       Currently Qt4 and Qt5 are supported.  When this property is set ON, 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, header files with the same base name (like foo.h) or _p appended to
       the base name (like foo_p.h) are parsed for Q_OBJECT macros, and if  found,  moc  is  also
       executed  on  those files.  AUTOMOC checks multiple header alternative extensions, such as
       hpp, hxx etc when searching for headers.  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  CMAKE_AUTOMOC variable 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 enabling the CMAKE_AUTOMOC_RELAXED_MODE variable the  rules  for  searching  the  files
       which  will  be  processed by moc can be relaxed.  See the documentation for this variable
       for more details.

       The global property AUTOGEN_TARGETS_FOLDER can  be  used  to  group  the  automoc  targets
       together in an IDE, e.g.  in MSVS.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   AUTOUIC
       Should the target be processed with autouic (for Qt projects).

       AUTOUIC  is  a  boolean  specifying  whether  CMake  will handle the Qt uic code generator
       automatically, i.e. without having  to  use  the  QT4_WRAP_UI()  or  QT5_WRAP_UI()  macro.
       Currently Qt4 and Qt5 are supported.

       When  this  property  is ON, CMake will scan the source files at build time and invoke uic
       accordingly.  If an #include statement like #include "ui_foo.h" is  found  in  foo.cpp,  a
       foo.ui file is expected next to foo.cpp, and uic is run on the foo.ui file.  This property
       is initialized by the value of the CMAKE_AUTOUIC variable if it is set when  a  target  is
       created.

       Additional  command  line  options  for uic can be set via the AUTOUIC_OPTIONS source file
       property on the foo.ui file.  The global property AUTOGEN_TARGETS_FOLDER can  be  used  to
       group the autouic targets together in an IDE, e.g. in MSVS.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   AUTOUIC_OPTIONS
       Additional options for uic when using AUTOUIC

       This  property  holds  additional  command  line  options  which  will be used when uic is
       executed during the build via AUTOUIC, i.e. it  is  equivalent  to  the  optional  OPTIONS
       argument of the qt4_wrap_ui() macro.

       By default it is empty.

       This  property  is initialized by the value of the CMAKE_AUTOUIC_OPTIONS variable if it is
       set when a target is created.

       The options set on the target may be overridden by AUTOUIC_OPTIONS set on the  .ui  source
       file.

       This   property  may  use  "generator  expressions"  with  the  syntax  $<...>.   See  the
       cmake-generator-expressions(7) manual for available expressions.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   AUTORCC
       Should the target be processed with autorcc (for Qt projects).

       AUTORCC is a boolean specifying whether CMake  will  handle  the  Qt  rcc  code  generator
       automatically,  i.e.  without having to use the QT4_ADD_RESOURCES() or QT5_ADD_RESOURCES()
       macro.  Currently Qt4 and Qt5 are supported.

       When this property is ON, CMake will handle .qrc files added as target  sources  at  build
       time  and  invoke  rcc  accordingly.   This  property  is  initialized by the value of the
       CMAKE_AUTORCC variable if it is set when a target is created.

       Additional command line options for rcc can be set via  the  AUTORCC_OPTIONS  source  file
       property on the .qrc file.

       The  global  property  AUTOGEN_TARGETS_FOLDER  can  be  used  to group the autorcc targets
       together in an IDE, e.g. in MSVS.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   AUTORCC_OPTIONS
       Additional options for rcc when using AUTORCC

       This property holds additional command line  options  which  will  be  used  when  rcc  is
       executed  during  the  build  via  AUTORCC,  i.e. it is equivalent to the optional OPTIONS
       argument of the qt4_add_resources() macro.

       By default it is empty.

       This property is initialized by the value of the CMAKE_AUTORCC_OPTIONS variable if  it  is
       set when a target is created.

       The  options set on the target may be overridden by AUTORCC_OPTIONS set on the .qrc source
       file.

       See the cmake-qt(7) manual for more information on using CMake with Qt.

   BINARY_DIR
       This read-only property reports the value of the CMAKE_CURRENT_BINARY_DIR variable in  the
       directory in which the target was defined.

   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_EXTENSION
       The file extension used to name a BUNDLE target on the OS X and iOS.

       The default value is bundle - you can also  use  plugin  or  whatever  file  extension  is
       required by the host app for your bundle.

   BUNDLE
       This target is a CFBundle on the OS X.

       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.

   C_EXTENSIONS
       Boolean specifying whether compiler specific extensions are requested.

       This  property  specifies  whether  compiler specific extensions should be used.  For some
       compilers, this results in adding a flag such as -std=gnu11 instead  of  -std=c11  to  the
       compile line.  This property is ON by default.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

       This property is initialized by the value of the CMAKE_C_EXTENSIONS variable if it is  set
       when a target is created.

   C_STANDARD
       The C standard whose features are requested to build this target.

       This  property specifies the C standard whose features are requested to build this target.
       For some compilers, this results in adding a flag such as -std=gnu11 to the compile  line.
       For compilers that have no notion of a standard level, such as MSVC, this has no effect.

       Supported values are 90, 99 and 11.

       If  the  value requested does not result in a compile flag being added for the compiler in
       use, a previous standard flag will be added instead.  This means that using:

          set_property(TARGET tgt PROPERTY C_STANDARD 11)

       with a compiler which does not support -std=gnu11 or an equivalent flag will not result in
       an  error or warning, but will instead add the -std=gnu99 or -std=gnu90 flag if supported.
       This "decay" behavior may be controlled with the C_STANDARD_REQUIRED target property.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

       This  property  is  initialized by the value of the CMAKE_C_STANDARD variable if it is set
       when a target is created.

   C_STANDARD_REQUIRED
       Boolean describing whether the value of C_STANDARD is a requirement.

       If this property is set to ON, then the value of the C_STANDARD target property is treated
       as  a  requirement.   If  this property is OFF or unset, the C_STANDARD target property is
       treated as optional and may "decay" to  a  previous  standard  if  the  requested  is  not
       available.   For compilers that have no notion of a standard level, such as MSVC, this has
       no effect.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

       This  property is initialized by the value of the CMAKE_C_STANDARD_REQUIRED variable if it
       is set when a target is created.

   COMPATIBLE_INTERFACE_BOOL
       Properties which must be compatible with their link interface

       The COMPATIBLE_INTERFACE_BOOL property may contain a list of properties  for  this  target
       which  must  be  consistent  when evaluated as a boolean with the INTERFACE variant of the
       property in all linked dependees.  For example, if a property FOO  appears  in  the  list,
       then for each dependee, the INTERFACE_FOO property content in all of its dependencies must
       be consistent with each other, and with the FOO property in the depender.

       Consistency in this sense has the meaning that if the property is set, then it  must  have
       the same boolean value as all others, and if the property is not set, then it is ignored.

       Note  that  for  each  dependee, the set of properties specified in this property must not
       intersect with the set specified in any of the other Compatible Interface Properties.

   COMPATIBLE_INTERFACE_NUMBER_MAX
       Properties whose maximum value from the link interface will be used.

       The COMPATIBLE_INTERFACE_NUMBER_MAX property may contain a list  of  properties  for  this
       target  whose  maximum  value may be read at generate time when evaluated in the INTERFACE
       variant of the property in all linked dependees.  For example, if a property  FOO  appears
       in  the  list,  then  for  each dependee, the INTERFACE_FOO property content in all of its
       dependencies will be compared with each other and with the FOO property in  the  depender.
       When reading the FOO property at generate time, the maximum value will be returned. If the
       property is not set, then it is ignored.

       Note that for each dependee, the set of properties specified in  this  property  must  not
       intersect with the set specified in any of the other Compatible Interface Properties.

   COMPATIBLE_INTERFACE_NUMBER_MIN
       Properties whose maximum value from the link interface will be used.

       The  COMPATIBLE_INTERFACE_NUMBER_MIN  property  may  contain a list of properties for this
       target whose minimum value may be read at generate time when evaluated  in  the  INTERFACE
       variant  of  the property of all linked dependees.  For example, if a property FOO appears
       in the list, then for each dependee, the INTERFACE_FOO property  content  in  all  of  its
       dependencies  will  be compared with each other and with the FOO property in the depender.
       When reading the FOO property at generate time, the minimum value will  be  returned.   If
       the property is not set, then it is ignored.

       Note  that  for  each  dependee, the set of properties specified in this property must not
       intersect with the set specified in any of the other Compatible Interface Properties.

   COMPATIBLE_INTERFACE_STRING
       Properties which must be string-compatible with their link interface

       The COMPATIBLE_INTERFACE_STRING property may contain a list of properties for this  target
       which must be the same when evaluated as a string in the INTERFACE variant of the property
       all linked dependees.  For example, if a property FOO appears in the list, then  for  each
       dependee, the INTERFACE_FOO property content in all of its dependencies must be equal with
       each other, and with the FOO property in the depender.  If the property is not  set,  then
       it is ignored.

       Note  that  for  each  dependee, the set of properties specified in this property must not
       intersect with the set specified in any of the other Compatible Interface Properties.

   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).

       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 7.0 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.

       Contents  of  COMPILE_DEFINITIONS  may use "generator expressions" with the syntax $<...>.
       See  the  cmake-generator-expressions(7)  manual  for  available  expressions.   See   the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

       The   corresponding   COMPILE_DEFINITIONS_<CONFIG>   property   may   be  set  to  specify
       per-configuration definitions.  Generator  expressions  should  be  preferred  instead  of
       setting the alternative property.

   COMPILE_FEATURES
       Compiler features enabled for this target.

       The  list  of  features  in  this  property  are  a  subset  of the features listed in the
       CMAKE_CXX_COMPILE_FEATURES variable.

       Contents of COMPILE_FEATURES may use "generator expressions" with the syntax $<...>.   See
       the   cmake-generator-expressions(7)   manual   for   available   expressions.    See  the
       cmake-compile-features(7) manual for  information  on  compile  features  and  a  list  of
       supported compilers.

   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.

       This   property   is   deprecated.    Use   the   COMPILE_OPTIONS    property    or    the
       target_compile_options command instead.

   COMPILE_OPTIONS
       List of options to pass to the compiler.

       This  property  holds  a  ;-list  of  options  specified  so  far for its target.  Use the
       target_compile_options() command to append more options.

       This property is intialized by the COMPILE_OPTIONS directory property  when  a  target  is
       created, and is used by the generators to set the options for the compiler.

       Contents  of  COMPILE_OPTIONS may use "generator expressions" with the syntax $<...>.  See
       the  cmake-generator-expressions(7)   manual   for   available   expressions.    See   the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   COMPILE_PDB_NAME
       Output  name  for  the  MS debug symbol .pdb file generated by the compiler while building
       source files.

       This property specifies the base name for the debug symbols file.  If not set, the default
       is unspecified.

       NOTE:
          The  compiler-generated  program  database files are specified by the /Fd compiler flag
          and are not the same as linker-generated program database files specified by  the  /pdb
          linker flag.  Use the PDB_NAME property to specify the latter.

          This property is not implemented by the Visual Studio 6 generator.

   COMPILE_PDB_NAME_<CONFIG>
       Per-configuration  output name for the MS debug symbol .pdb file generated by the compiler
       while building source files.

       This is the configuration-specific version of COMPILE_PDB_NAME.

       NOTE:
          The compiler-generated program database files are specified by the  /Fd  compiler  flag
          and  are  not the same as linker-generated program database files specified by the /pdb
          linker flag.  Use the PDB_NAME_<CONFIG> property to specify the latter.

          This property is not implemented by the Visual Studio 6 generator.

   COMPILE_PDB_OUTPUT_DIRECTORY
       Output directory for the MS debug  symbol  .pdb  file  generated  by  the  compiler  while
       building source files.

       This  property  specifies  the directory into which the MS debug symbols will be placed by
       the   compiler.    This   property    is    initialized    by    the    value    of    the
       CMAKE_COMPILE_PDB_OUTPUT_DIRECTORY variable if it is set when a target is created.

       NOTE:
          The  compiler-generated  program  database files are specified by the /Fd compiler flag
          and are not the same as linker-generated program database files specified by  the  /pdb
          linker flag.  Use the PDB_OUTPUT_DIRECTORY property to specify the latter.

          This property is not implemented by the Visual Studio 6 generator.

   COMPILE_PDB_OUTPUT_DIRECTORY_<CONFIG>
       Per-configuration  output  directory  for  the  MS debug symbol .pdb file generated by the
       compiler while building source files.

       This   is   a   per-configuration    version    of    COMPILE_PDB_OUTPUT_DIRECTORY,    but
       multi-configuration  generators (VS, Xcode) do NOT append a per-configuration subdirectory
       to  the  specified  directory.   This  property  is  initialized  by  the  value  of   the
       CMAKE_COMPILE_PDB_OUTPUT_DIRECTORY_<CONFIG>  variable  if  it  is  set  when  a  target is
       created.

       NOTE:
          The compiler-generated program database files are specified by the  /Fd  compiler  flag
          and  are  not the same as linker-generated program database files specified by the /pdb
          linker flag.  Use the PDB_OUTPUT_DIRECTORY_<CONFIG> property to specify the latter.

          This property is not implemented by the Visual Studio 6 generator.

   <CONFIG>_OUTPUT_NAME
       Old per-configuration target file base name.  Use OUTPUT_NAME_<CONFIG> instead.

       This is a configuration-specific version of the OUTPUT_NAME target property.

   <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.

   CROSSCOMPILING_EMULATOR
       Use  the given emulator to run executables created when crosscompiling.  This command will
       be added as a prefix to add_test() test commands for built target system executables.

   CXX_EXTENSIONS
       Boolean specifying whether compiler specific extensions are requested.

       This property specifies whether compiler specific extensions should  be  used.   For  some
       compilers, this results in adding a flag such as -std=gnu++11 instead of -std=c++11 to the
       compile line.  This property is ON by default.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

       This  property  is  initialized by the value of the CMAKE_CXX_EXTENSIONS variable if it is
       set when a target is created.

   CXX_STANDARD
       The C++ standard whose features are requested to build this target.

       This property specifies the C++ standard  whose  features  are  requested  to  build  this
       target.   For  some  compilers,  this results in adding a flag such as -std=gnu++11 to the
       compile line.  For compilers that have no notion of a standard level, such as  MSVC,  this
       has no effect.

       Supported values are 98, 11 and 14.

       If  the  value requested does not result in a compile flag being added for the compiler in
       use, a previous standard flag will be added instead.  This means that using:

          set_property(TARGET tgt PROPERTY CXX_STANDARD 11)

       with a compiler which does not support -std=gnu++11 or an equivalent flag will not  result
       in  an  error  or  warning, but will instead add the -std=gnu++98 flag if supported.  This
       "decay" behavior may be controlled with the CXX_STANDARD_REQUIRED target property.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

       This  property is initialized by the value of the CMAKE_CXX_STANDARD variable if it is set
       when a target is created.

   CXX_STANDARD_REQUIRED
       Boolean describing whether the value of CXX_STANDARD is a requirement.

       If this property is set to ON, then the value  of  the  CXX_STANDARD  target  property  is
       treated  as  a  requirement.   If  this  property is OFF or unset, the CXX_STANDARD target
       property is treated as optional and may "decay" to a previous standard if the requested is
       not  available.  For compilers that have no notion of a standard level, such as MSVC, this
       has no effect.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

       This  property  is initialized by the value of the CMAKE_CXX_STANDARD_REQUIRED variable if
       it is set when a target is created.

   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  or  outside  to  properly
       setup dllexport/dllimport decorations.

   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.

   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  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.

       This  property  is  initialized by the value of the variable CMAKE_ENABLE_EXPORTS if it is
       set when a target is created.

   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.

   EXCLUDE_FROM_DEFAULT_BUILD_<CONFIG>
       Per-configuration version of target exclusion from "Build Solution".

       This  is the configuration-specific version of EXCLUDE_FROM_DEFAULT_BUILD.  If the generic
       EXCLUDE_FROM_DEFAULT_BUILD is also set on  a  target,  EXCLUDE_FROM_DEFAULT_BUILD_<CONFIG>
       takes precedence in configurations for which it has a value.

   EXCLUDE_FROM_DEFAULT_BUILD
       Exclude target from "Build Solution".

       This property is only used by Visual Studio generators 7 and above.  When set to TRUE, the
       target will not be built when you press "Build Solution".

   EXPORT_NAME
       Exported name for target files.

       This sets the name for the IMPORTED target generated when it this target is  is  exported.
       If not set, the logical target name is used by default.

   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.

   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.

   FRAMEWORK
       Build SHARED library as Framework Bundle on the OS X and iOS.

       If  a  SHARED library target has this property set to TRUE it will be built as a framework
       when built on the OS X and iOS.  It will have  the  directory  structure  required  for  a
       framework and will be suitable to be used with the -framework option

       To  customize  Info.plist  file  in  the framework, use MACOSX_FRAMEWORK_INFO_PLIST target
       property.

       For OS X see also the FRAMEWORK_VERSION target property.

       Example of creation dynamicFramework:

          add_library(dynamicFramework SHARED
                      dynamicFramework.c
                      dynamicFramework.h
          )
          set_target_properties(dynamicFramework PROPERTIES
            FRAMEWORK TRUE
            FRAMEWORK_VERSION C
            MACOSX_FRAMEWORK_IDENTIFIER com.cmake.dynamicFramework
            MACOSX_FRAMEWORK_INFO_PLIST Info.plist
            PUBLIC_HEADER dynamicFramework.h
            XCODE_ATTRIBUTE_CODE_SIGN_IDENTITY "iPhone Developer"
          )

   FRAMEWORK_VERSION
       Version of a framework created using the FRAMEWORK target property (e.g. A).

       This property only affects OS X, as iOS doesn't have versioned directory structure.

   GENERATOR_FILE_NAME
       Generator's file for this target.

       An internal property used by some generators to record the name of the project or dsp file
       associated  with  this target.  Note that at configure time, this property is only set for
       targets created by include_external_msproject().

   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_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_<CONFIG>
       <CONFIG>-specific version of IMPORTED_IMPLIB property.

       Configuration names correspond to those provided by the project from which the  target  is
       imported.

   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_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_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 INTERFACE_LINK_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_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_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_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.

       This  property  is  ignored  if  the  target also has a non-empty INTERFACE_LINK_LIBRARIES
       property.

       This property is deprecated.  Use INTERFACE_LINK_LIBRARIES instead.

   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.

       This property is ignored if the  target  also  has  a  non-empty  INTERFACE_LINK_LIBRARIES
       property.

       This property is deprecated.  Use INTERFACE_LINK_LIBRARIES instead.

   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_LINK_INTERFACE_MULTIPLICITY
       Repetition count for cycles of IMPORTED static libraries.

       This is LINK_INTERFACE_MULTIPLICITY for IMPORTED targets.

   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_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_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_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
       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_SONAME_<CONFIG>
       <CONFIG>-specific version of IMPORTED_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.

   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
       target_include_directories() command.  In addition to accepting values from that  command,
       values  may be set directly on any target using the set_property() command.  A target gets
       its initial value for this property from the value of  the  INCLUDE_DIRECTORIES  directory
       property.   Both  directory  and  target  property  values  are  adjusted  by calls to the
       include_directories() command.

       The value of this property is used by the generators to set  the  include  paths  for  the
       compiler.

       Relative  paths  should  not  be  added to this property directly. Use one of the commands
       above instead to handle relative paths.

       Contents of INCLUDE_DIRECTORIES may use "generator expressions" with  the  syntax  $<...>.
       See   the  cmake-generator-expressions(7)  manual  for  available  expressions.   See  the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   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.

   INTERFACE_AUTOUIC_OPTIONS
       List of interface options to pass to uic.

       Targets may populate this property to publish the options required to  use  when  invoking
       uic.   Consuming  targets  can  add  entries to their own AUTOUIC_OPTIONS property such as
       $<TARGET_PROPERTY:foo,INTERFACE_AUTOUIC_OPTIONS> to use the uic options specified  in  the
       interface of foo. This is done automatically by the target_link_libraries() command.

       This  property  supports  generator  expressions.   See the cmake-generator-expressions(7)
       manual for available expressions.

   INTERFACE_COMPILE_DEFINITIONS
       List of public compile definitions requirements for a library.

       Targets may populate this property to publish the compile definitions required to  compile
       against  the  headers  for the target.  The target_compile_definitions() command populates
       this property with values given to the PUBLIC and INTERFACE keywords.  Projects  may  also
       get and set the property directly.

       When target dependencies are specified using target_link_libraries(), CMake will read this
       property from all target dependencies to determine the build properties of the consumer.

       Contents of INTERFACE_COMPILE_DEFINITIONS may use "generator expressions" with the  syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) -manual for more on defining buildsystem properties.

   INTERFACE_COMPILE_FEATURES
       List of public compile features requirements for a library.

       Targets may populate this property to publish the compile  features  required  to  compile
       against  the headers for the target.  The target_compile_features() command populates this
       property with values given to the PUBLIC and INTERFACE keywords.  Projects  may  also  get
       and set the property directly.

       When target dependencies are specified using target_link_libraries(), CMake will read this
       property from all target dependencies to determine the build properties of the consumer.

       Contents of INTERFACE_COMPILE_FEATURES may use "generator  expressions"  with  the  syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) -manual for more on defining buildsystem properties.

       See the cmake-compile-features(7) manual for information on compile features and a list of
       supported compilers.

   INTERFACE_COMPILE_OPTIONS
       List of public compile options requirements for a library.

       Targets  may  populate  this  property  to publish the compile options required to compile
       against the headers for the target.  The target_compile_options() command  populates  this
       property  with  values  given to the PUBLIC and INTERFACE keywords.  Projects may also get
       and set the property directly.

       When target dependencies are specified using target_link_libraries(), CMake will read this
       property from all target dependencies to determine the build properties of the consumer.

       Contents  of  INTERFACE_COMPILE_OPTIONS  may  use  "generator expressions" with the syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) -manual for more on defining buildsystem properties.

   INTERFACE_INCLUDE_DIRECTORIES
       List of public include directories requirements for a library.

       Targets  may populate this property to publish the include directories required to compile
       against the headers for the target.  The  target_include_directories()  command  populates
       this  property  with values given to the PUBLIC and INTERFACE keywords.  Projects may also
       get and set the property directly.

       When target dependencies are specified using target_link_libraries(), CMake will read this
       property from all target dependencies to determine the build properties of the consumer.

       Contents  of INTERFACE_INCLUDE_DIRECTORIES may use "generator expressions" with the syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) -manual for more on defining buildsystem properties.

       Include  directories  usage  requirements  commonly  differ between the build-tree and the
       install-tree.  The BUILD_INTERFACE and INSTALL_INTERFACE generator expressions can be used
       to  describe  separate usage requirements based on the usage location.  Relative paths are
       allowed within the INSTALL_INTERFACE  expression  and  are  interpreted  relative  to  the
       installation prefix.  For example:

          target_include_directories(mylib INTERFACE
            $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/include/mylib>
            $<INSTALL_INTERFACE:include/mylib>  # <prefix>/include/mylib
          )

   Creating Relocatable Packages
       Note   that   it   is   not   advisable   to   populate   the   INSTALL_INTERFACE  of  the
       INTERFACE_INCLUDE_DIRECTORIES of a target with absolute paths to the  include  directories
       of dependencies.  That would hard-code into installed packages the include directory paths
       for dependencies as found on the machine the package was made on.

       The INSTALL_INTERFACE of the INTERFACE_INCLUDE_DIRECTORIES is only suitable for specifying
       the  required  include  directories for headers provided with the target itself, not those
       provided by the transitive dependencies  listed  in  its  INTERFACE_LINK_LIBRARIES  target
       property.   Those  dependencies should themselves be targets that specify their own header
       locations in INTERFACE_INCLUDE_DIRECTORIES.

       See the  Creating  Relocatable  Packages  section  of  the  cmake-packages(7)  manual  for
       discussion  of additional care that must be taken when specifying usage requirements while
       creating packages for redistribution.

   INTERFACE_LINK_LIBRARIES
       List public interface libraries for a library.

       This property contains the list of transitive  link  dependencies.   When  the  target  is
       linked into another target using the target_link_libraries() command, the libraries listed
       (and recursively their link interface libraries) will be  provided  to  the  other  target
       also.     This    property    is    overridden    by   the   LINK_INTERFACE_LIBRARIES   or
       LINK_INTERFACE_LIBRARIES_<CONFIG> property if policy CMP0022 is OLD or unset.

       Contents of INTERFACE_LINK_LIBRARIES may  use  "generator  expressions"  with  the  syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   Creating Relocatable Packages
       Note that it is not advisable to populate the INTERFACE_LINK_LIBRARIES of  a  target  with
       absolute  paths to dependencies.  That would hard-code into installed packages the library
       file paths for dependencies as found on the machine the package was made on.

       See the  Creating  Relocatable  Packages  section  of  the  cmake-packages(7)  manual  for
       discussion  of additional care that must be taken when specifying usage requirements while
       creating packages for redistribution.

   INTERFACE_POSITION_INDEPENDENT_CODE
       Whether consumers need to create a position-independent target

       The INTERFACE_POSITION_INDEPENDENT_CODE property informs consumers of this target  whether
       they  must set their POSITION_INDEPENDENT_CODE property to ON.  If this property is set to
       ON, then the POSITION_INDEPENDENT_CODE property on  all  consumers  will  be  set  to  ON.
       Similarly,  if this property is set to OFF, then the POSITION_INDEPENDENT_CODE property on
       all consumers will be set to OFF.  If this property  is  undefined,  then  consumers  will
       determine  their POSITION_INDEPENDENT_CODE property by other means.  Consumers must ensure
       that  the  targets  that  they  link  to  have  a   consistent   requirement   for   their
       INTERFACE_POSITION_INDEPENDENT_CODE property.

   INTERFACE_SOURCES
       List of interface sources to compile into consuming targets.

       Targets  may  populate  this  property  to  publish  the  sources for consuming targets to
       compile.  The target_sources() command populates this property with values  given  to  the
       PUBLIC and INTERFACE keywords.  Projects may also get and set the property directly.

       When target dependencies are specified using target_link_libraries(), CMake will read this
       property from all target dependencies to determine the sources of the consumer.

       Contents of INTERFACE_SOURCES may use "generator expressions" with the syntax $<...>.  See
       the   cmake-generator-expressions(7)   manual   for   available   expressions.    See  the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   INTERFACE_SYSTEM_INCLUDE_DIRECTORIES
       List of public system include directories for a library.

       Targets may populate this property to publish the include directories which contain system
       headers,    and    therefore    should    not    result   in   compiler   warnings.    The
       target_include_directories(SYSTEM) command signature populates this property  with  values
       given to the PUBLIC and INTERFACE keywords.

       Projects  may  also  get  and  set  the  property  directly, but must be aware that adding
       directories to this property does not make  those  directories  used  during  compilation.
       Adding  directories  to this property marks directories as SYSTEM which otherwise would be
       used in a non-SYSTEM manner.  This can appear similar  to  'duplication',  so  prefer  the
       high-level  target_include_directories(SYSTEM)  command  and avoid setting the property by
       low-level means.

       When target dependencies are specified using target_link_libraries(), CMake will read this
       property  from  all target dependencies to mark the same include directories as containing
       system headers.

       Contents of INTERFACE_SYSTEM_INCLUDE_DIRECTORIES may use "generator expressions" with  the
       syntax  $<...>.   See the cmake-generator-expressions(7) manual for available expressions.
       See the cmake-buildsystem(7) manual for more on defining buildsystem properties.

   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.

   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.

   IOS_INSTALL_COMBINED
       Build a combined (device and simulator) target when installing.

       When this property is set to set to false (which is the default) then it  will  either  be
       built  with  the  device  SDK  or  the simulator SDK depending on the SDK set. But if this
       property is set to true then the target will  at  install  time  also  be  built  for  the
       corresponding SDK and combined into one library.

       This feature requires at least Xcode version 6.

   JOB_POOL_COMPILE
       Ninja only: Pool used for compiling.

       The  number  of  parallel  compile  processes  could be limited by defining pools with the
       global JOB_POOLS property and then specifying here the pool name.

       For instance:

          set_property(TARGET myexe PROPERTY JOB_POOL_COMPILE ten_jobs)

       This property is initialized by the value of CMAKE_JOB_POOL_COMPILE.

   JOB_POOL_LINK
       Ninja only: Pool used for linking.

       The number of parallel link processes could be limited by defining pools with  the  global
       JOB_POOLS property and then specifing here the pool name.

       For instance:

          set_property(TARGET myexe PROPERTY JOB_POOL_LINK two_jobs)

       This property is initialized by the value of CMAKE_JOB_POOL_LINK.

   LABELS
       Specify a list of text labels associated with a target.

       Target label semantics are currently unspecified.

   <LANG>_COMPILER_LAUNCHER
       This property is implemented only when <LANG> is C or CXX.

       Specify  a  ;-list  containing  a command line for a compiler launching tool. The Makefile
       Generators and the Ninja generator will run this  tool  and  pass  the  compiler  and  its
       arguments to the tool. Some example tools are distcc and ccache.

       This  property  is initialized by the value of the CMAKE_<LANG>_COMPILER_LAUNCHER variable
       if it is set when a target is created.

   <LANG>_INCLUDE_WHAT_YOU_USE
       This property is implemented only when <LANG> is C or CXX.

       Specify a ;-list containing  a  command  line  for  the  include-what-you-use  tool.   The
       Makefile Generators and the Ninja generator will run this tool along with the compiler and
       report a warning if the tool reports any problems.

       This property  is  initialized  by  the  value  of  the  CMAKE_<LANG>_INCLUDE_WHAT_YOU_USE
       variable if it is set when a target is created.

   <LANG>_VISIBILITY_PRESET
       Value for symbol visibility compile flags

       The  <LANG>_VISIBILITY_PRESET property determines the value passed in a visibility related
       compile option, such as -fvisibility= for <LANG>.  This property  affects  compilation  in
       sources of all types of targets (subject to policy CMP0063).

       This  property  is initialized by the value of the CMAKE_<LANG>_VISIBILITY_PRESET variable
       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 the LIBRARY_OUTPUT_DIRECTORY target  property,  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
       CMAKE_LIBRARY_OUTPUT_DIRECTORY_<CONFIG> variable if it is set when a target is created.

       Contents of LIBRARY_OUTPUT_DIRECTORY_<CONFIG> may use generator expressions.

   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.
       The property value may use generator  expressions.   Multi-configuration  generators  (VS,
       Xcode)  append  a  per-configuration  subdirectory  to  the  specified  directory unless a
       generator expression is used.

       This property is initialized by the value of the  variable  CMAKE_LIBRARY_OUTPUT_DIRECTORY
       if it is set when a target is created.

       See also the LIBRARY_OUTPUT_DIRECTORY_<CONFIG> target property.

   LIBRARY_OUTPUT_NAME_<CONFIG>
       Per-configuration output name for LIBRARY target files.

       This is the configuration-specific version of the LIBRARY_OUTPUT_NAME target property.

   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.

       See also the LIBRARY_OUTPUT_NAME_<CONFIG> target property.

   LINK_DEPENDS_NO_SHARED
       Do not depend on linked shared library files.

       Set this property to true to tell CMake generators not to add file-level  dependencies  on
       the shared library files linked by this target.  Modification to the shared libraries will
       not be sufficient to re-link this target.  Logical target-level dependencies will  not  be
       affected  so  the  linked  shared  libraries  will still be brought up to date before this
       target is built.

       This property is initialized by the value of the variable CMAKE_LINK_DEPENDS_NO_SHARED  if
       it is set when a target is created.

   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.

   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.

       If this property is not set by the user, it will be calculated at generate-time by CMake.

   LINK_FLAGS_<CONFIG>
       Per-configuration linker flags for a target.

       This is the configuration-specific version of LINK_FLAGS.

   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_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.

       This  property is overridden by the INTERFACE_LINK_LIBRARIES property if policy CMP0022 is
       NEW.

       This property is deprecated.  Use INTERFACE_LINK_LIBRARIES instead.

   Creating Relocatable Packages
       Note that it is not advisable  to  populate  the  LINK_INTERFACE_LIBRARIES_<CONFIG>  of  a
       target  with absolute paths to dependencies.  That would hard-code into installed packages
       the library file paths for dependencies as found on the machine the package was made on.

       See the  Creating  Relocatable  Packages  section  of  the  cmake-packages(7)  manual  for
       discussion  of additional care that must be taken when specifying usage requirements while
       creating packages for redistribution.

   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 target
       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 using the target_link_libraries() command, 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 CMAKE_LINK_INTERFACE_LIBRARIES variable if  it  is  set
       when a target is created.  This property is ignored for STATIC libraries.

       This  property is overridden by the INTERFACE_LINK_LIBRARIES property if policy CMP0022 is
       NEW.

       This property is deprecated.  Use INTERFACE_LINK_LIBRARIES instead.

   Creating Relocatable Packages
       Note that it is not advisable to populate the LINK_INTERFACE_LIBRARIES of  a  target  with
       absolute  paths to dependencies.  That would hard-code into installed packages the library
       file paths for dependencies as found on the machine the package was made on.

       See the  Creating  Relocatable  Packages  section  of  the  cmake-packages(7)  manual  for
       discussion  of additional care that must be taken when specifying usage requirements while
       creating packages for redistribution.

   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_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_LIBRARIES
       List of direct link dependencies.

       This property specifies the list of libraries or targets which will be used  for  linking.
       In  addition  to  accepting values from the target_link_libraries() command, values may be
       set directly on any target using the set_property() command.

       The value of this property is used by the generators to set the  link  libraries  for  the
       compiler.

       Contents  of  LINK_LIBRARIES  may use "generator expressions" with the syntax $<...>.  See
       the  cmake-generator-expressions(7)   manual   for   available   expressions.    See   the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   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.

       This property is initialized by the value of the variable CMAKE_LINK_SEARCH_END_STATIC  if
       it is set when a target is created.

       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).

       This  property  is initialized by the value of the variable CMAKE_LINK_SEARCH_START_STATIC
       if it is set when a target is created.

       See also LINK_SEARCH_END_STATIC.

   LOCATION_<CONFIG>
       Read-only property providing a target location on disk.

       A read-only property that indicates where a target's main file is located on disk for  the
       configuration  <CONFIG>.  The property is defined only for library and executable targets.
       An imported target may provide  a  set  of  configurations  different  from  that  of  the
       importing  project.   By  default  CMake  looks  for  an exact-match but otherwise uses an
       arbitrary available configuration.  Use the MAP_IMPORTED_CONFIG_<CONFIG> property  to  map
       imported configurations explicitly.

       Do  not  set  properties that affect the location of a target after reading this property.
       These          include          properties           whose           names           match
       "(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIRECTORY)(_<CONFIG>)?",
       (IMPLIB_)?(PREFIX|SUFFIX), or "LINKER_LANGUAGE".  Failure  to  follow  this  rule  is  not
       diagnosed and leaves the location of the target undefined.

   LOCATION
       Read-only location of a target on disk.

       For an imported target, this read-only property returns the value of the LOCATION_<CONFIG>
       property for an unspecified configuration <CONFIG> provided by the target.

       For a non-imported target, this property is provided for compatibility with CMake 2.4  and
       below.   It was meant to get the location of an executable target's output file for use in
       add_custom_command.  The path may contain a build-system-specific portion that is replaced
       at build time with the configuration getting built (such as "$(ConfigurationName)" in VS).
       In CMake 2.6 and above add_custom_command automatically recognizes a target  name  in  its
       COMMAND  and  DEPENDS  options and computes the target location.  In CMake 2.8.4 and above
       add_custom_command recognizes generator expressions to refer to target locations  anywhere
       in the command.  Therefore this property is not needed for creating custom commands.

       Do  not  set  properties that affect the location of a target after reading this property.
       These          include          properties           whose           names           match
       "(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIRECTORY)(_<CONFIG>)?",
       (IMPLIB_)?(PREFIX|SUFFIX), or "LINKER_LANGUAGE".  Failure  to  follow  this  rule  is  not
       diagnosed and leaves the location of the target undefined.

   MACOSX_BUNDLE_INFO_PLIST
       Specify a custom Info.plist template for a OS X and iOS Application Bundle.

       An  executable target with MACOSX_BUNDLE enabled will be built as an application bundle on
       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_BUNDLE_NAME
              Sets CFBundleName.

       MACOSX_BUNDLE_BUNDLE_VERSION
              Sets CFBundleVersion.

       MACOSX_BUNDLE_COPYRIGHT
              Sets NSHumanReadableCopyright.

       MACOSX_BUNDLE_GUI_IDENTIFIER
              Sets CFBundleIdentifier.

       MACOSX_BUNDLE_ICON_FILE
              Sets CFBundleIconFile.

       MACOSX_BUNDLE_INFO_STRING
              Sets CFBundleGetInfoString.

       MACOSX_BUNDLE_LONG_VERSION_STRING
              Sets CFBundleLongVersionString.

       MACOSX_BUNDLE_SHORT_VERSION_STRING
              Sets CFBundleShortVersionString.

       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_BUNDLE
       Build an executable as an Application Bundle on OS X or iOS.

       When this property is set to TRUE the executable when built on OS X or iOS will be created
       as an application bundle.  This makes it a GUI executable that can be  launched  from  the
       Finder.   See  the  MACOSX_FRAMEWORK_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_FRAMEWORK_INFO_PLIST
       Specify a custom Info.plist template for a OS X and iOS Framework.

       A  library target with FRAMEWORK enabled will be built as a framework on 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_BUNDLE_VERSION
              Sets CFBundleVersion.

       MACOSX_FRAMEWORK_ICON_FILE
              Sets CFBundleIconFile.

       MACOSX_FRAMEWORK_IDENTIFIER
              Sets CFBundleIdentifier.

       MACOSX_FRAMEWORK_SHORT_VERSION_STRING
              Sets CFBundleShortVersionString.

       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_RPATH
       Whether this target on OS X or iOS is located at runtime using rpaths.

       When this property is set to TRUE, the directory portion of the install_name field of this
       shared library will be @rpath unless overridden by INSTALL_NAME_DIR.  This  indicates  the
       shared library is to be found at runtime using runtime paths (rpaths).

       This  property is initialized by the value of the variable CMAKE_MACOSX_RPATH if it is set
       when a target is created.

       Runtime paths will also be embedded in binaries using this target and can be controlled by
       the INSTALL_RPATH target property on the target linking to this target.

       Policy  CMP0042  was introduced to change the default value of MACOSX_RPATH to TRUE.  This
       is because use of @rpath is a more flexible and powerful alternative  to  @executable_path
       and @loader_path.

   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.

       This    property    is    initialized     by     the     value     of     the     variable
       CMAKE_MAP_IMPORTED_CONFIG_<CONFIG> if it is set when a target is created.

   NAME
       Logical name for the target.

       Read-only logical name for the target as used by CMake.

   NO_SONAME
       Whether to set "soname" when linking a shared library.

       Enable  this  boolean property if a generated shared library should not have "soname" set.
       Default is to set "soname" on all shared libraries 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.

   NO_SYSTEM_FROM_IMPORTED
       Do not treat includes from IMPORTED target interfaces as SYSTEM.

       The  contents  of  the  INTERFACE_INCLUDE_DIRECTORIES  of  IMPORTED targets are treated as
       SYSTEM  includes  by  default.   If  this  property  is  enabled,  the  contents  of   the
       INTERFACE_INCLUDE_DIRECTORIES  of  IMPORTED  targets  are  not treated as system includes.
       This property is initialized by the value of the variable CMAKE_NO_SYSTEM_FROM_IMPORTED if
       it is set when a target is created.

   OSX_ARCHITECTURES_<CONFIG>
       Per-configuration OS X and iOS binary architectures for a target.

       This property is the configuration-specific version of OSX_ARCHITECTURES.

   OSX_ARCHITECTURES
       Target specific architectures for OS X.

       The  OSX_ARCHITECTURES  property  sets  the target binary architecture for targets on OS X
       (-arch).    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,
       where <CONFIG> is an upper-case name (e.g. OSX_ARCHITECTURES_DEBUG).

   OUTPUT_NAME_<CONFIG>
       Per-configuration target file base name.

       This is the configuration-specific version of the OUTPUT_NAME target property.

   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.

       Contents of OUTPUT_NAME and the variants listed below may use generator expressions.

       See also the variants:

       • OUTPUT_NAME_<CONFIG>ARCHIVE_OUTPUT_NAME_<CONFIG>ARCHIVE_OUTPUT_NAMELIBRARY_OUTPUT_NAME_<CONFIG>LIBRARY_OUTPUT_NAMERUNTIME_OUTPUT_NAME_<CONFIG>RUNTIME_OUTPUT_NAME

   PDB_NAME_<CONFIG>
       Per-configuration output name for the MS debug symbol .pdb file generated  by  the  linker
       for an executable or shared library target.

       This is the configuration-specific version of PDB_NAME.

       NOTE:
          This  property does not apply to STATIC library targets because no linker is invoked to
          produce them so they have no linker-generated .pdb file containing debug symbols.

          The linker-generated program database files are specified by the /pdb linker  flag  and
          are  not  the  same  as  compiler-generated program database files specified by the /Fd
          compiler flag.  Use the COMPILE_PDB_NAME_<CONFIG> property to specify the latter.

          This property is not implemented by the Visual Studio 6 generator.

   PDB_NAME
       Output name for the MS debug symbol .pdb file generated by the linker for an executable or
       shared library target.

       This  property  specifies  the  base  name  for  the  debug symbols file.  If not set, the
       OUTPUT_NAME target property value or logical target name is used by default.

       NOTE:
          This property does not apply to STATIC library targets because no linker is invoked  to
          produce them so they have no linker-generated .pdb file containing debug symbols.

          The  linker-generated  program database files are specified by the /pdb linker flag and
          are not the same as compiler-generated program database  files  specified  by  the  /Fd
          compiler flag.  Use the COMPILE_PDB_NAME property to specify the latter.

          This property is not implemented by the Visual Studio 6 generator.

   PDB_OUTPUT_DIRECTORY_<CONFIG>
       Per-configuration  output  directory  for  the  MS debug symbol .pdb file generated by the
       linker for an executable or shared library target.

       This is a  per-configuration  version  of  PDB_OUTPUT_DIRECTORY,  but  multi-configuration
       generators  (VS,  Xcode)  do  NOT append a per-configuration subdirectory to the specified
       directory.     This    property    is    initialized    by    the     value     of     the
       CMAKE_PDB_OUTPUT_DIRECTORY_<CONFIG> variable if it is set when a target is created.

       NOTE:
          This  property does not apply to STATIC library targets because no linker is invoked to
          produce them so they have no linker-generated .pdb file containing debug symbols.

          The linker-generated program database files are specified by the /pdb linker  flag  and
          are  not  the  same  as  compiler-generated program database files specified by the /Fd
          compiler flag.  Use the COMPILE_PDB_OUTPUT_DIRECTORY_<CONFIG> property to  specify  the
          latter.

          This property is not implemented by the Visual Studio 6 generator.

   PDB_OUTPUT_DIRECTORY
       Output  directory  for  the  MS  debug  symbols  .pdb  file generated by the linker for an
       executable or shared library target.

       This property specifies the directory into which the MS debug symbols will  be  placed  by
       the  linker.   This property is initialized by the value of the CMAKE_PDB_OUTPUT_DIRECTORY
       variable if it is set when a target is created.

       NOTE:
          This property does not apply to STATIC library targets because no linker is invoked  to
          produce them so they have no linker-generated .pdb file containing debug symbols.

          The  linker-generated  program database files are specified by the /pdb linker flag and
          are not the same as compiler-generated program database  files  specified  by  the  /Fd
          compiler flag.  Use the COMPILE_PDB_OUTPUT_DIRECTORY property to specify the latter.

          This property is not implemented by the Visual Studio 6 generator.

   POSITION_INDEPENDENT_CODE
       Whether to create a position-independent target

       The POSITION_INDEPENDENT_CODE property determines whether position independent executables
       or shared libraries will be created.  This property is True  by  default  for  SHARED  and
       MODULE  library targets and False otherwise.  This property is initialized by the value of
       the CMAKE_POSITION_INDEPENDENT_CODE variable  if it is set when a target is created.

   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.

   PRIVATE_HEADER
       Specify private header files in a FRAMEWORK shared library target.

       Shared library targets marked with the FRAMEWORK property generate frameworks on OS X, iOS
       and normal shared libraries on other platforms.  This property may be set  to  a  list  of
       header files to be placed in the PrivateHeaders directory inside the framework folder.  On
       non-Apple platforms these headers may be installed using the PRIVATE_HEADER option to  the
       install(TARGETS) command.

   PROJECT_LABEL
       Change the name of a target in an IDE.

       Can be used to change the name of the target in an IDE like Visual Studio.

   PUBLIC_HEADER
       Specify public header files in a FRAMEWORK shared library target.

       Shared library targets marked with the FRAMEWORK property generate frameworks on OS X, iOS
       and normal shared libraries on other platforms.  This property may be set  to  a  list  of
       header  files  to  be  placed  in  the  Headers directory inside the framework folder.  On
       non-Apple platforms these headers may be installed using the PUBLIC_HEADER option  to  the
       install(TARGETS) command.

   RESOURCE
       Specify resource files in a FRAMEWORK or BUNDLE.

       Target  marked  with  the  FRAMEWORK  or BUNDLE property generate framework or application
       bundle (both OS X and iOS is supported) or normal shared  libraries  on  other  platforms.
       This  property  may  be set to a list of files to be placed in the corresponding directory
       (eg. Resources directory for OS X) inside the bundle.  On non-Apple platforms these  files
       may be installed using the RESOURCE option to the install(TARGETS) command.

       Following example of Application Bundle:

          add_executable(ExecutableTarget
            addDemo.c
            resourcefile.txt
            appresourcedir/appres.txt
          )

          target_link_libraries(ExecutableTarget heymath mul)

          set(RESOURCE_FILES
            resourcefile.txt
            appresourcedir/appres.txt
          )

          set_target_properties(ExecutableTarget PROPERTIES
            MACOSX_BUNDLE TRUE
            MACOSX_FRAMEWORK_IDENTIFIER org.cmake.ExecutableTarget
            RESOURCE "${RESOURCE_FILES}"
          )

       will produce flat structure for iOS systems:

          ExecutableTarget.app
            appres.txt
            ExecutableTarget
            Info.plist
            resourcefile.txt

       For OS X systems it will produce following directory structure:

          ExecutableTarget.app/

   RULE_LAUNCH_COMPILE
       Specify a launcher for compile rules.

       See  the  global  property  of  the  same name for details.  This overrides the global and
       directory property for a target.

   RULE_LAUNCH_CUSTOM
       Specify a launcher for custom rules.

       See the global property of the same name for  details.   This  overrides  the  global  and
       directory property for a target.

   RULE_LAUNCH_LINK
       Specify a launcher for link rules.

       See  the  global  property  of  the  same name for details.  This overrides the global and
       directory property for a target.

   RUNTIME_OUTPUT_DIRECTORY_<CONFIG>
       Per-configuration output directory for RUNTIME target files.

       This is a per-configuration version of the RUNTIME_OUTPUT_DIRECTORY target  property,  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
       CMAKE_RUNTIME_OUTPUT_DIRECTORY_<CONFIG> variable if it is set when a target is created.

       Contents of RUNTIME_OUTPUT_DIRECTORY_<CONFIG> may use generator expressions.

   RUNTIME_OUTPUT_DIRECTORY
       Output directory in which to build RUNTIME target files.

       This  property  specifies  the  directory into which runtime target files should be built.
       The property value may use generator  expressions.   Multi-configuration  generators  (VS,
       Xcode)  append  a  per-configuration  subdirectory  to  the  specified  directory unless a
       generator expression is used.

       This property is initialized by the value of the  variable  CMAKE_RUNTIME_OUTPUT_DIRECTORY
       if it is set when a target is created.

       See also the RUNTIME_OUTPUT_DIRECTORY_<CONFIG> target property.

   RUNTIME_OUTPUT_NAME_<CONFIG>
       Per-configuration output name for RUNTIME target files.

       This is the configuration-specific version of the RUNTIME_OUTPUT_NAME target property.

   RUNTIME_OUTPUT_NAME
       Output name for RUNTIME target files.

       This  property specifies the base name for runtime target files.  It overrides OUTPUT_NAME
       and OUTPUT_NAME_<CONFIG> properties.

       See also the RUNTIME_OUTPUT_NAME_<CONFIG> target property.

   SKIP_BUILD_RPATH
       Should rpaths be used for the build tree.

       SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic generation of an  rpath
       allowing the target to run from the build tree.  This property is initialized by the value
       of the variable CMAKE_SKIP_BUILD_RPATH if it is set when a target is created.

   SOURCE_DIR
       This read-only property reports the value of the CMAKE_CURRENT_SOURCE_DIR variable in  the
       directory in which the target was defined.

   SOURCES
       Source names specified for a target.

       List of sources specified for a target.

   SOVERSION
       What version number is this target.

       For  shared  libraries  VERSION and SOVERSION can be used to specify the build version and
       API version respectively.  When building or installing appropriate symlinks are created if
       the  platform  supports symlinks and the linker supports so-names.  If only one of both is
       specified the missing is assumed to have the same version number.  SOVERSION is ignored if
       NO_SONAME  property  is  set.  For shared libraries and executables on Windows the VERSION
       attribute is parsed to extract a "major.minor" version number.  These numbers are used  as
       the image version of the binary.

   STATIC_LIBRARY_FLAGS_<CONFIG>
       Per-configuration flags for creating a static library.

       This is the configuration-specific version of STATIC_LIBRARY_FLAGS.

   STATIC_LIBRARY_FLAGS
       Extra flags to use when linking static libraries.

       Extra flags to use when linking a static library.

   SUFFIX
       What comes after the target name.

       A  target property that can be set to override the suffix (such as ".so" or ".exe") on the
       name of a library, module or executable.

   TYPE
       The type of the target.

       This read-only property can be used to test the type of the given target.  It will be  one
       of STATIC_LIBRARY, MODULE_LIBRARY, SHARED_LIBRARY, INTERFACE_LIBRARY, EXECUTABLE or one of
       the internal target types.

   VERSION
       What version number is this target.

       For shared libraries VERSION and SOVERSION can be used to specify the  build  version  and
       API version respectively.  When building or installing appropriate symlinks are created if
       the platform supports symlinks and the linker supports so-names.  If only one of  both  is
       specified the missing is assumed to have the same version number.  For executables VERSION
       can be used to specify  the  build  version.   When  building  or  installing  appropriate
       symlinks  are  created  if  the  platform  supports  symlinks.   For  shared libraries and
       executables on Windows the VERSION attribute is parsed to extract a "major.minor"  version
       number.  These numbers are used as the image version of the binary.

   VISIBILITY_INLINES_HIDDEN
       Whether to add a compile flag to hide symbols of inline functions

       The  VISIBILITY_INLINES_HIDDEN  property  determines whether a flag for hiding symbols for
       inline functions, such as -fvisibility-inlines-hidden, should be used  when  invoking  the
       compiler.   This  property affects compilation in sources of all types of targets (subject
       to policy CMP0063).

       This property is initialized by the value of the CMAKE_VISIBILITY_INLINES_HIDDEN  variable
       if it is set when a target is created.

   VS_DESKTOP_EXTENSIONS_VERSION
       Visual Studio Windows 10 Desktop Extensions Version

       Specifies the version of the Desktop Extensions that should be included in the target. For
       example 10.0.10240.0. If the value is not specified, the Desktop Extensions  will  not  be
       included.  To  use  the same version of the extensions as the Windows 10 SDK that is being
       used, you can use the CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION variable.

   VS_DOTNET_REFERENCES
       Visual Studio managed project .NET references

       Adds one or more semicolon-delimited .NET references to a generated Visual Studio project.
       For example, "System;System.Windows.Forms".

   VS_DOTNET_TARGET_FRAMEWORK_VERSION
       Specify the .NET target framework version.

       Used to specify the .NET target framework version for C++/CLI.  For example, "v4.5".

   VS_GLOBAL_KEYWORD
       Visual Studio project keyword for VS 10 (2010) and newer.

       Sets  the  "keyword"  attribute  for  a  generated  Visual  Studio  project.   Defaults to
       "Win32Proj".  You may wish to override this value with "ManagedCProj", for example,  in  a
       Visual Studio managed C++ unit test project.

       Use  the  VS_KEYWORD  target  property  to  set the keyword for Visual Studio 9 (2008) and
       older.

   VS_GLOBAL_PROJECT_TYPES
       Visual Studio project type(s).

       Can be set to one or more UUIDs recognized by  Visual  Studio  to  indicate  the  type  of
       project.   This  value  is copied verbatim into the generated project file.  Example for a
       managed C++ unit testing project:

          {3AC096D0-A1C2-E12C-1390-A8335801FDAB};{8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942}

       UUIDs are semicolon-delimited.

   VS_GLOBAL_ROOTNAMESPACE
       Visual Studio project root namespace.

       Sets the "RootNamespace" attribute for a generated Visual Studio project.   The  attribute
       will be generated only if this is set.

   VS_GLOBAL_<variable>
       Visual Studio project-specific global variable.

       Tell  the Visual Studio generator to set the global variable '<variable>' to a given value
       in the generated Visual Studio project.  Ignored  on  other  generators.   Qt  integration
       works  better  if  VS_GLOBAL_QtVersion  is  set  to  the version FindQt4.cmake found.  For
       example, "4.7.3"

   VS_IOT_EXTENSIONS_VERSION
       Visual Studio Windows 10 IoT Extensions Version

       Specifies the version of the IoT Extensions that should be included  in  the  target.  For
       example  10.0.10240.0.  If  the  value  is  not  specified, the IoT Extensions will not be
       included. To use the same version of the extensions as the Windows 10 SDK  that  is  being
       used, you can use the CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION variable.

   VS_IOT_STARTUP_TASK
       Visual Studio Windows 10 IoT Continuous Background Task

       Specifies that the target should be compiled as a Continuous Background Task library.

   VS_KEYWORD
       Visual Studio project keyword for VS 9 (2008) and older.

       Can be set to change the visual studio keyword, for example Qt integration works better if
       this is set to Qt4VSv1.0.

       Use the VS_GLOBAL_KEYWORD target property to set the keyword for Visual Studio  10  (2010)
       and newer.

   VS_MOBILE_EXTENSIONS_VERSION
       Visual Studio Windows 10 Mobile Extensions Version

       Specifies  the version of the Mobile Extensions that should be included in the target. For
       example 10.0.10240.0. If the value is not specified, the Mobile  Extensions  will  not  be
       included.  To  use  the same version of the extensions as the Windows 10 SDK that is being
       used, you can use the CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION variable.

   VS_SCC_AUXPATH
       Visual Studio Source Code Control Aux Path.

       Can be set to change the visual studio source code control auxpath property.

   VS_SCC_LOCALPATH
       Visual Studio Source Code Control Local Path.

       Can be set to change the visual studio source code control local path property.

   VS_SCC_PROJECTNAME
       Visual Studio Source Code Control Project.

       Can be set to change the visual studio source code control project name property.

   VS_SCC_PROVIDER
       Visual Studio Source Code Control Provider.

       Can be set to change the visual studio source code control provider property.

   VS_WINDOWS_TARGET_PLATFORM_MIN_VERSION
       Visual Studio Windows Target Platform Minimum Version

       For Windows 10. Specifies the minimum version of  the  OS  that  is  being  targeted.  For
       example    10.0.10240.0.    If    the    value    is   not   specified,   the   value   of
       CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION will be used on WindowsStore  projects  otherwise
       the target platform minimum version will not be specified for the project.

   VS_WINRT_COMPONENT
       Mark a target as a Windows Runtime component for the Visual Studio generator.  Compile the
       target with C++/CX language  extensions  for  Windows  Runtime.   For  SHARED  and  MODULE
       libraries, this also defines the _WINRT_DLL preprocessor macro.

       NOTE:
          Currently  this  is implemented only by Visual Studio generators.  Support may be added
          to other generators in the future.

   VS_WINRT_EXTENSIONS
       Deprecated.  Use VS_WINRT_COMPONENT instead.  This property was  an  experimental  partial
       implementation of that one.

   VS_WINRT_REFERENCES
       Visual Studio project Windows Runtime Metadata references

       Adds  one  or  more  semicolon-delimited  WinRT  references  to  a generated Visual Studio
       project.  For example, "Windows;Windows.UI.Core".

   WIN32_EXECUTABLE
       Build an executable with a WinMain entry point on windows.

       When this property is set to true the executable when linked on Windows  will  be  created
       with  a  WinMain()  entry  point  instead  of just main().  This makes it a GUI executable
       instead of a console  application.   See  the  CMAKE_MFC_FLAG  variable  documentation  to
       configure  use  of MFC for WinMain executables.  This property is initialized by the value
       of the variable CMAKE_WIN32_EXECUTABLE if it is set when a target is created.

   WINDOWS_EXPORT_ALL_SYMBOLS
       This property is implemented only for MS-compatible tools on Windows.

       Enable this boolean property to automatically create a module definition (.def) file  with
       all  global  symbols  found  in the input .obj files for a SHARED library on Windows.  The
       module definition file will be passed to the linker causing all  symbols  to  be  exported
       from  the  .dll.   For  global data symbols, __declspec(dllimport) must still be used when
       compiling against the code in the .dll.  All other function symbols will be  automatically
       exported and imported by callers.  This simplifies porting projects to Windows by reducing
       the need for explicit dllexport markup, even in C++ classes.

       This property is initialized by the value of the CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS variable
       if it is set when a target is created.

   XCODE_ATTRIBUTE_<an-attribute>
       Set Xcode target attributes directly.

       Tell  the  Xcode generator to set '<an-attribute>' to a given value in the generated Xcode
       project.  Ignored on other generators.

       See the CMAKE_XCODE_ATTRIBUTE_<an-attribute> variable to set attributes on all targets  in
       a directory tree.

       Contents of XCODE_ATTRIBUTE_<an-attribute> may use "generator expressions" with the syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

   XCTEST
       This target is a XCTest CFBundle on the Mac.

       This property will usually get set via the xctest_add_bundle() macro in FindXCTest module.

       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.

       This property depends on BUNDLE to be effective.

PROPERTIES ON TESTS

   ATTACHED_FILES_ON_FAIL
       Attach a list of files to a dashboard submission if the test fails.

       Same as ATTACHED_FILES, but these files will only be included if the test does not pass.

   ATTACHED_FILES
       Attach a list of files to a dashboard submission.

       Set this property to a list of files that will be encoded and submitted to  the  dashboard
       as an addition to the test result.

   COST
       Set this to a floating point value. Tests in a test set will be run in descending order of
       cost.

       This property describes the cost of a test.  You can explicitly set this value; tests with
       higher COST values will run first.

   DEPENDS
       Specifies that this test should only be run after the specified list of tests.

       Set this to a list of tests that must finish before this test is run.

   ENVIRONMENT
       Specify environment variables that should be defined for running a test.

       If  set  to  a  list  of  environment  variables  and values of the form MYVAR=value those
       environment variables will be defined while running the test.  The environment is restored
       to its previous state after the test is done.

   FAIL_REGULAR_EXPRESSION
       If the output matches this regular expression the test will fail.

       If  set,  if  the output matches one of specified regular expressions, the test will fail.
       Example:

          set_tests_properties(mytest PROPERTIES
            FAIL_REGULAR_EXPRESSION "[^a-z]Error;ERROR;Failed"
          )

       FAIL_REGULAR_EXPRESSION expects a list of regular expressions.

   LABELS
       Specify a list of text labels associated with a test.

       The list is reported in dashboard submissions.

   MEASUREMENT
       Specify a CDASH measurement and value to be reported for a test.

       If set to a name then that name will be reported to CDASH as a named  measurement  with  a
       value of 1.  You may also specify a value by setting MEASUREMENT to "measurement=value".

   PASS_REGULAR_EXPRESSION
       The output must match this regular expression for the test to pass.

       If  set,  the test output will be checked against the specified regular expressions and at
       least one of the regular expressions has to match, otherwise the test will fail.  Example:

          set_tests_properties(mytest PROPERTIES
            PASS_REGULAR_EXPRESSION "TestPassed;All ok"
          )

       PASS_REGULAR_EXPRESSION expects a list of regular expressions.

   PROCESSORS
       How many process slots this test requires

       Denotes the number of processors that this test will require.  This is typically used  for
       MPI tests, and should be used in conjunction with the ctest_test PARALLEL_LEVEL option.

   REQUIRED_FILES
       List of files required to run the test.

       If set to a list of files, the test will not be run unless all of the files exist.

   RESOURCE_LOCK
       Specify a list of resources that are locked by this test.

       If  multiple  tests  specify  the  same  resource  lock,  they  are  guaranteed not to run
       concurrently.

   RUN_SERIAL
       Do not run this test in parallel with any other test.

       Use this option in conjunction with the ctest_test PARALLEL_LEVEL option to  specify  that
       this test should not be run in parallel with any other tests.

   SKIP_RETURN_CODE
       Return code to mark a test as skipped.

       Sometimes  only  a  test itself can determine if all requirements for the test are met. If
       such a situation should not be considered a hard failure a return code of the process  can
       be specified that will mark the test as "Not Run" if it is encountered.

   TIMEOUT
       How many seconds to allow for this test.

       This  property  if  set  will  limit  a test to not take more than the specified number of
       seconds to run.  If it exceeds that the test process will be killed and ctest will move to
       the next test.  This setting takes precedence over CTEST_TEST_TIMEOUT.

   WILL_FAIL
       If set to true, this will invert the pass/fail flag of the test.

       This property can be used for tests that are expected to fail and return a non zero return
       code.

   WORKING_DIRECTORY
       The directory from which the test executable will be called.

       If this is not set it is called from the directory the test executable is located in.

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.

   AUTOUIC_OPTIONS
       Additional options for uic when using AUTOUIC

       This property holds additional command line  options  which  will  be  used  when  uic  is
       executed  during  the  build  via  AUTOUIC,  i.e. it is equivalent to the optional OPTIONS
       argument of the qt4_wrap_ui() macro.

       By default it is empty.

       The options set on the .ui source file may override AUTOUIC_OPTIONS set on the target.

   AUTORCC_OPTIONS
       Additional options for rcc when using AUTORCC

       This property holds additional command line  options  which  will  be  used  when  rcc  is
       executed  during  the  build  via  AUTORCC,  i.e. it is equivalent to the optional OPTIONS
       argument of the qt4_add_resources() macro.

       By default it is empty.

       The options set on the .qrc source file may override AUTORCC_OPTIONS set on the target.

   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 7.0 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_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 if 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 headers 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 Application Bundle (MACOSX_BUNDLE),  Core  Foundation  Bundle
       (BUNDLE), or Framework Bundle (FRAMEWORK).  It is applicable for OS X and iOS.

       Executable  targets  with  the  MACOSX_BUNDLE  property  set  are  built  as  OS  X or iOS
       application bundles on  Apple  platforms.   Shared  library  targets  with  the  FRAMEWORK
       property  set  are  built  as  OS  X or iOS frameworks on Apple platforms.  Module library
       targets with the BUNDLE property  set  are  built  as  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  OS  X  Application  Bundles  the  content  folder  is  <name>.app/Contents.  For OS X
       Frameworks the content folder is <name>.framework/Versions/<version>.  For OS X  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  ;-list  of  full-paths to files on which any object files compiled from this
       source file depend.  On Makefile Generators and the Ninja generator an object file will be
       recompiled  if  any of the named files is newer than it.  Visual Studio Generators and the
       Xcode generator cannot implement such compilation dependencies.

       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.

   VS_DEPLOYMENT_CONTENT
       Mark  a  source  file  as  content  for  deployment  with a Windows Phone or Windows Store
       application when built with a Visual Studio generator.  The value must evaluate to  either
       1  or  0  and  may  use  generator  expressions  to  make  the  choice  based on the build
       configuration.  The .vcxproj file  entry  for  the  source  file  will  be  marked  either
       DeploymentContent or ExcludedFromBuild for values 1 and 0, respectively.

   VS_DEPLOYMENT_LOCATION
       Specifies  the  deployment  location  for  a  content  source file with a Windows Phone or
       Windows Store application when built with a Visual Studio  generator.   This  property  is
       only  applicable  when using VS_DEPLOYMENT_CONTENT.  The value represent the path relative
       to the app package and applies to all configurations.

   VS_SHADER_ENTRYPOINT
       Specifies the name of the entry point for the shader of a .hlsl source file.

   VS_SHADER_FLAGS
       Set additional VS shader flags of a .hlsl source file.

   VS_SHADER_MODEL
       Specifies the shader model of a .hlsl source file. Some shader types can only be used with
       recent shader models

   VS_SHADER_TYPE
       Set the VS shader type of a .hlsl source file.

   VS_XAML_TYPE
       Mark  a XAML source file as a different type than the default Page.  The most common usage
       would be to set the default App.xaml file as ApplicationDefinition.

   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 that this source  file  should
       not be wrapped.

   XCODE_EXPLICIT_FILE_TYPE
       Set  the  Xcode  explicitFileType  attribute  on  its  reference  to a source file.  CMake
       computes a default based on file extension but can be told explicitly with this property.

       See also XCODE_LAST_KNOWN_FILE_TYPE.

   XCODE_LAST_KNOWN_FILE_TYPE
       Set the Xcode lastKnownFileType attribute on  its  reference  to  a  source  file.   CMake
       computes a default based on file extension but can be told explicitly with this property.

       See also XCODE_EXPLICIT_FILE_TYPE, which is preferred over this property if 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 INSTALLED FILES

   CPACK_DESKTOP_SHORTCUTS
       Species a list of shortcut names that should be created on the Desktop for this file.

       The property is currently only supported by the WIX generator.

   CPACK_NEVER_OVERWRITE
       Request that this file not be overwritten on install or reinstall.

       The property is currently only supported by the WIX generator.

   CPACK_PERMANENT
       Request that this file not be removed on uninstall.

       The property is currently only supported by the WIX generator.

   CPACK_START_MENU_SHORTCUTS
       Species a list of shortcut names that should be created in the Start Menu for this file.

       The property is currently only supported by the WIX generator.

   CPACK_STARTUP_SHORTCUTS
       Species  a  list  of  shortcut names that should be created in the Startup folder for this
       file.

       The property is currently only supported by the WIX generator.

   CPACK_WIX_ACL
       Specifies access permissions for files or directories installed by a WiX installer.

       The property can contain multiple list entries, each of which has to match  the  following
       format.

          <user>[@<domain>]=<permission>[,<permission>]

       <user> and <domain> specify the windows user and domain for which the <Permission> element
       should be generated.

       <permission> is any of the YesNoType attributes listed here:

          http://wixtoolset.org/documentation/manual/v3/xsd/wix/permission.html

DEPRECATED PROPERTIES ON DIRECTORIES

   COMPILE_DEFINITIONS_<CONFIG>
       Ignored.  See CMake Policy CMP0043.

       Per-configuration preprocessor definitions in a directory.

       This is the configuration-specific version of COMPILE_DEFINITIONS  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.

       Contents of COMPILE_DEFINITIONS_<CONFIG> may use "generator expressions" with  the  syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

       Generator expressions should be preferred instead of setting this property.

DEPRECATED PROPERTIES ON TARGETS

   COMPILE_DEFINITIONS_<CONFIG>
       Ignored.  See CMake Policy CMP0043.

       Per-configuration preprocessor definitions on a target.

       This is the configuration-specific version of COMPILE_DEFINITIONS  where  <CONFIG>  is  an
       upper-case name (ex. COMPILE_DEFINITIONS_DEBUG).

       Contents  of  COMPILE_DEFINITIONS_<CONFIG> may use "generator expressions" with the syntax
       $<...>.  See the cmake-generator-expressions(7) manual for available expressions.  See the
       cmake-buildsystem(7) manual for more on defining buildsystem properties.

       Generator expressions should be preferred instead of setting this property.

   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.

   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.

DEPRECATED PROPERTIES ON SOURCE FILES

   COMPILE_DEFINITIONS_<CONFIG>
       Ignored.  See CMake Policy CMP0043.

       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.
