[CMake] normalize paths

[James Bigler]

Ugh, I forgot about get_filename_component:

            get_filename_component(VarName FileName
                                   PATH|ABSOLUTE|NAME|EXT|NAME_WE|REALPATH
                                   [CACHE])

ABSOLUTE seems to normalize the file paths.
