OK, indeed. So we've got different solutions here:

 1. Use an explicit Config.in choice, like you did.

 2. Use automatic dependencies like I suggested, but enable only one
    backend at a time if both Qt and Gtk are enabled.

I guess the solution (1) you initially proposed is OK.

Thanks,

Thomas
