"There are two main signatures for add_custom_command "
"The first signature is for adding a custom command "
"to produce an output.\n"
" add_custom_command(OUTPUT output1 [output2 ...]\n"

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

"This defines a command to generate specified OUTPUT file(s). "
"A target created in the same directory (CMakeLists.txt file) that "
"specifies any output of the custom command as a source file is given "
"a rule to generate the file using the command at build time. "
"Do not list the output in more than one independent target that may "
"build in parallel or the two instances of the rule may conflict "
"(instead use add_custom_target to drive the command and make the "
"other targets depend on that one). "
"If an output name is a relative path it will be interpreted "
"relative to the build tree directory corresponding to the current "
"source directory. "
"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. "
"The command becomes part of the target and will only execute "
"when the target itself is built. If the target is already built,"
" the command will not execute.\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 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. "
"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 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_command 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."
"\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.\n"
"The IMPLICIT_DEPENDS option requests scanning of implicit "
"dependencies of an input file. The language given specifies the "
"programming language whose corresponding dependency scanner should "
"be used. Currently only C and CXX language scanners are supported. "
"The language has to be specified for every file in the "
"IMPLICIT_DEPENDS list. "
"Dependencies discovered from the scanning are added to those of "
"the custom command at build time. Note that the IMPLICIT_DEPENDS "
"option is currently supported only for Makefile generators and "
"will be ignored by other generators."
"\n"
"If COMMAND specifies an executable target (created by "
"ADD_EXECUTABLE) it will automatically be replaced by the location "
"of the executable created at build time. Additionally a "
"target-level dependency will be added so that the executable target "
"will be built before any target using this custom command. However "
"this does NOT add a file-level dependency that would cause the "
"custom command to re-run whenever the executable is recompiled."
"\n"
"Arguments to COMMAND may use \"generator expressions\" with the "
"syntax \"$<...>\". "
CM_DOCUMENT_COMMAND_GENERATOR_EXPRESSIONS
"References to target names in generator expressions imply "
"target-level dependencies, but NOT file-level dependencies. "
"List target names with the DEPENDS option to add file dependencies."
"\n"
"The DEPENDS option specifies files on which the command depends. "
"If any dependency is an OUTPUT of another custom command in the "
"same directory (CMakeLists.txt file) CMake automatically brings the "
"other custom command into the target in which this command is built. "
"If DEPENDS is not specified the command will run whenever the OUTPUT "
"is missing; if the command does not actually create the OUTPUT then "
"the rule will always run. "
"If DEPENDS specifies any target (created by an ADD_* command) "
"a target-level dependency is created to make sure the target is "
"built before any target using this custom command. Additionally, "
"if the target is an executable or library a file-level dependency "
"is created to cause the custom command to re-run whenever the target "
"is recompiled.\n"
