return

Return from a file, directory or function.

return()

Returns from a file, directory or function. When this command is encountered in an included file (via include() or find_package()), it causes processing of the current file to stop and control is returned to the including file. If it is encountered in a file which is not included by another file, e.g. a CMakeLists.txt, deferred calls scheduled by cmake_language(DEFER) are invoked and control is returned to the parent directory if there is one. If return is called in a function, control is returned to the caller of the function.

Note that a macro, unlike a function, is expanded in place and therefore cannot handle return().
