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, 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 is not a function and does not handle return like a
function does.
