"target. Use ADD_CUSTOM_COMMAND to generate a file with dependencies. "
"By default nothing depends on the custom target. Use "
"ADD_DEPENDENCIES to add dependencies to or from other targets. "
"If the ALL option is specified "
"it indicates that this target should be added to the default build "
"target so that it will be run every time "
"(the command cannot be called ALL). "
"The command and arguments are optional and if not specified an "
"empty target will be created. "
"If WORKING_DIRECTORY is set, then the command will be run in that "
"directory. "
"If COMMENT is set, the value will be displayed as a "
"message before the commands are executed at build time. "
"Dependencies listed with the DEPENDS argument may reference files "
"and outputs of custom commands created with ADD_CUSTOM_COMMAND.\n"
"If VERBATIM is given then all the arguments to the commands will be "
"passed exactly as specified no matter the build tool used. "
"Note that one level of escapes is still used by the CMake language "
"processor before ADD_CUSTOM_TARGET even sees the arguments. "
"Use of VERBATIM is recommended as it enables correct behavior. "
"When VERBATIM is not given the behavior is platform specific. "
"In the future VERBATIM may be enabled by default. The only reason "
"it is an option is to preserve compatibility with older CMake code.";
