This can be avoided by loading glib in runtime instead of compile time.
If glib is found, load it and register the types.

People will now quickly point out that an installed glib doesn't necessarily
mean that the application uses it. Personally I think it's not a big deal,
but it is possible to workaround that by checking if a glib specific symbol
such as g_type_init is available in the main executable, eg if the
executable was linked against glib and only then register the types.

That should make everybody happy.
