"The target has no output file and is ALWAYS CONSIDERED OUT OF DATE "
"even if the commands try to create a file with the name of the "
"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 it is a relative path it will be interpreted relative to the "
"build tree directory corresponding to the current source 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() in "
"the same directory (CMakeLists.txt file).\n"
"If VERBATIM is given then all arguments to the commands will be "
"escaped properly for the build tool so that the invoked command "
"receives each argument unchanged. "
"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 because "
"there is no protection of tool-specific special characters."

"The SOURCES option specifies additional source files to be included "
"in the custom target. "
"Specified source files will be added to IDE project files for "
"convenience in editing even if they have not build rules."
