        "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.  "
        "Properties that cmake knows about are PREFIX and SUFFIX for UNIX "
        "systems and libraries.   CMake also knows about LINK_FLAGS, which "
        "can be used to add extra flags to the link step of a target. "
        "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). "
        "PRE_INSTALL_SCRIPT specifies a CMake script that is run "
        "prior to installing the target. POST_INSTALL_SCRIPT specifies "
        "a CMake script that is run after target is installed. "
        "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. "
        "The OUTPUT_NAME can be used to set an output name that is "
        "used in place of the target name when creating executables.\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). "
        "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. When the target is created the values of "
        "the variables CMAKE_INSTALL_RPATH, CMAKE_SKIP_BUILD_RPATH, and "
        "CMAKE_BUILD_WITH_INSTALL_RPATH 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. "
        "You can use any prop value pair you want and "
        "extract it later with the GET_TARGET_PROPERTY command.";
