" [COMMAND command2 [ARGS] [args2...] ...]\n"

" [COMMENT comment])\n"
"This defines a new command that can be executed during the build "
"process. The outputs named should be listed as source files in the "
"target for which they are to be generated. "
"Note that MAIN_DEPENDENCY is completely optional and is "
"used as a suggestion to visual studio about where to hang the "
"custom command. In makefile terms this creates a new target in the "
"following form:\n"
" OUTPUT: MAIN_DEPENDENCY DEPENDS\n"
" COMMAND\n"
"If more than one command is specified they will be executed in order. "
"The optional ARGS argument is for backward compatibility and will be "
"ignored.\n"
"The second signature adds a custom command to a target "
"such as a library or executable. This is useful for "
"performing an operation before or after building the target:\n"
" ADD_CUSTOM_COMMAND(TARGET target\n"
" PRE_BUILD | PRE_LINK | POST_BUILD\n"
" COMMAND command1 [ARGS] [args1...]\n"
" [COMMAND command2 [ARGS] [args2...] ...]\n"
" [WORKING_DIRECTORY dir]\n"
" [COMMENT comment])\n"
"This defines a new command that will be associated with "
"building the specified target. When the command will "
"happen is determined by which of the following is specified:\n"
" PRE_BUILD - run before all other dependencies\n"
" PRE_LINK - run after other dependencies\n"
" POST_BUILD - run after the target has been built\n"
"Note that the PRE_BUILD option is only supported on Visual "
"Studio 7 or later. For all other generators PRE_BUILD "
"will be treated as PRE_LINK. "
"If WORKING_DIRECTORY is specified the command will be executed "
"in the directory given.";
