|
" ADD_CUSTOM_COMMAND(OUTPUT output1 [output2 ...]\n"
|
|
" COMMAND command1 [ARGS] [args1...]\n"

|
" [COMMAND command2 [ARGS] [args2...] ...]\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] [VERBATIM])\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.\n"
|
|
"If WORKING_DIRECTORY is specified the command will be executed "
|
|
"in the directory given. "
|
|
"If COMMENT is set, the value will be displayed as a "
|
|
"message before the commands are executed at build time. "
|
|
"If APPEND is specified the COMMAND and DEPENDS option values "
|
|
"are appended to the custom command for the first output specified. "
|
|
"There must have already been a previous call to this command with "
|
|
"the same output. The COMMENT, WORKING_DIRECTORY, and MAIN_DEPENDENCY "
|
|
"options are currently ignored when APPEND is given, "
|
|
"but may be used in the future."
|
|
"\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.\n"
|
|
"If the output of the custom command is not actually "
|
|
"created as a file on disk it should be marked as SYMBOLIC with "
|

"SET_SOURCE_FILES_PROPERTIES.";
