  94         "for example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO. "
  95         "DEFINE_SYMBOL sets the name of the preprocessor symbol defined when "

 101         "setup dllexport/dllimport decorations. "
 102         "The COMPILE_FLAGS property sets additional compiler flags used "
 103         "to build sources within the target.  It may also be used to pass "
 104         "additional preprocessor definitions."

 123         "\n"
 124         "There are a few properties used to specify RPATH rules. "
 125         "INSTALL_RPATH is a semicolon-separated list specifying the rpath "
 126         "to use in installed targets (for platforms that support it). "
 127         "INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true will "
 128         "append directories in the linker search path and outside the "
 129         "project to the INSTALL_RPATH. "
 130         "SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic "
 131         "generation of an rpath allowing the target to run from the "
 132         "build tree. "
 133         "BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link "
 134         "the target in the build tree with the INSTALL_RPATH.  This takes "
 135         "precedence over SKIP_BUILD_RPATH and avoids the need for relinking "
 136         "before installation.  INSTALL_NAME_DIR is a string specifying the "
 137         "directory portion of the \"install_name\" field of shared libraries "
 138         "on Mac OSX to use in the installed targets. "
 139         "When the target is created the values of "
 140         "the variables CMAKE_INSTALL_RPATH, "
 141         "CMAKE_INSTALL_RPATH_USE_LINK_PATH, CMAKE_SKIP_BUILD_RPATH, "

 146         "to change the visual studio keyword, for example QT integration "
 147         "works better if this is set to Qt4VSv1.0.\n"
 148         "When a library is built CMake by default generates code to remove "
 149         "any existing library using all possible names.  This is needed "
 150         "to support libraries that switch between STATIC and SHARED by "
 151         "a user option.  However when using OUTPUT_NAME to build a static "
 152         "and shared library of the same name using different logical target "
 153         "names the two targets will remove each other's files.  This can be "
 154         "prevented by setting the CLEAN_DIRECT_OUTPUT property to 1.\n"
 155         "The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the "
 156         "old way to specify CMake scripts to run before and after "
 157         "installing a target.  They are used only when the old "
 158         "INSTALL_TARGETS command is used to install the target.  Use the "
