I think it would be cleaner to make the second argument a non-optional
argument and always pass in the source directory (e.g. change the use of
add_version_info_from_vcs() within LLVM to pass in
CMAKE_CURRENT_SOURCE_DIR), that way we can get rid of the additional if
statement above.

Thanks for working on this!

Tilmann
