    MSVC builds: Generate .pc files for external packages
    
    That is, for Cairo, Freetype and libxml2, as packages that we support
    for Visual Studio builds depend on these packages, specifically for
    generating the introspection files for them.
    
    These are generated with rather generic info in them, so that they are
    sufficient for our purposes here.
