    Add Google Test and Google Mock
    
    Enabled with --enable-google-test, configure the location of the sources
    with --with-gtest-root, --with-gtest-headers, --with-gmock-root, and
    --with-gmock-headers. The latter isn't necessary if the headers are
    installed in /usr/include and the sources in /usr/src as the Debian
    packages do.
    
    This is a first-pass and needs to be made a bit more sophisticated later.
    It might also be worthwhile to extract it into an m4 macro.
