"Set properties on a target. The syntax for the command is to "
"list all the files you want "
"to change, and then provide the values you want to set next. "
"You can use any prop value pair you want and "
"extract it later with the GET_TARGET_PROPERTY command.\n"
"Properties that affect the name of a target's output file are "
"as follows. "
"The PREFIX and SUFFIX properties override the default target name "
"prefix (such as \"lib\") and suffix (such as \".so\"). "
"IMPORT_PREFIX and IMPORT_SUFFIX are the equivalent properties for "
"the import library corresponding to a DLL "
"(for SHARED library targets). "
"OUTPUT_NAME sets the real name of a target when it is built and "
"can be used to help create two targets of the same name even though "
"CMake requires unique logical target names. There is also a "
"<CONFIG>_OUTPUT_NAME that can set the output name on a "
"per-configuration basis. "
"<CONFIG>_POSTFIX sets a postfix for the real name of the target "
"when it is built under the configuration named by <CONFIG> "
"(in upper-case, such as \"DEBUG_POSTFIX\"). The value of "
"this property is initialized when the target is created to the "
"value of the variable CMAKE_<CONFIG>_POSTFIX (except for executable "
"targets because earlier CMake versions which did not use this "
"variable for executables)."
"\n"
"The LINK_FLAGS property can be used to add extra flags to the "
"link step of a target. LINK_FLAGS_<CONFIG> will add to the "
"configuration <CONFIG>, "
"for example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO. "
"DEFINE_SYMBOL sets the name of the preprocessor symbol defined when "
"compiling sources in a shared library. "
"If not set here then it is set to target_EXPORTS by default "
"(with some substitutions if the target is not a valid C "
"identifier). This is useful for headers to know whether they are "
"being included from inside their library our outside to properly "
"setup dllexport/dllimport decorations. "
"The COMPILE_FLAGS property sets additional compiler flags used "
"to build sources within the target. It may also be used to pass "
"additional preprocessor definitions."
"\n"
"The LINKER_LANGUAGE property is used to change the tool "
"used to link an executable or shared library. The default is "
"set the language to match the files in the library. CXX and C "
"are common values for this property."
"\n"
"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. "
"\n"
"There are a few properties used to specify RPATH rules. "
"INSTALL_RPATH is a semicolon-separated list specifying the rpath "
"to use in installed targets (for platforms that support it). "
"INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true will "
"append directories in the linker search path and outside the "
"project to the INSTALL_RPATH. "
"SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic "
"generation of an rpath allowing the target to run from the "
"build tree. "
"BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link "
"the target in the build tree with the INSTALL_RPATH. This takes "
"precedence over SKIP_BUILD_RPATH and avoids the need for relinking "
"before installation. INSTALL_NAME_DIR is a string specifying the "
"directory portion of the \"install_name\" field of shared libraries "
"on Mac OSX to use in the installed targets. "
"When the target is created the values of "
"the variables CMAKE_INSTALL_RPATH, "
"CMAKE_INSTALL_RPATH_USE_LINK_PATH, CMAKE_SKIP_BUILD_RPATH, "
"CMAKE_BUILD_WITH_INSTALL_RPATH, and CMAKE_INSTALL_NAME_DIR "
"are used to initialize these properties.\n"
"PROJECT_LABEL can be used to change the name of "
"the target in an IDE like visual studio. VS_KEYWORD can be set "
"to change the visual studio keyword, for example QT integration "
"works better if this is set to Qt4VSv1.0.\n"
"When a library is built CMake by default generates code to remove "
"any existing library using all possible names. This is needed "
"to support libraries that switch between STATIC and SHARED by "
"a user option. However when using OUTPUT_NAME to build a static "
"and shared library of the same name using different logical target "
"names the two targets will remove each other's files. This can be "
"prevented by setting the CLEAN_DIRECT_OUTPUT property to 1.\n"
"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."
