cmake.eclass: cmake_comment_add_subdirectory: optionally accept "-f <path>"
New function description:
Comment out one or more add_subdirectory calls with #DONOTBUILD in
a) a given file path (error out on nonexisting path)
b) a CMakeLists.txt file inside a given directory (ewarn if not found)
c) CMakeLists.txt in current directory (do nothing if not found).
c) is unchanged prior behaviour.
