This post concerns only gtkmm-4.0, wrapping the
still very unstable gtk4.
Gtk4 installs only one library file and one .pc
file. Bug https://bugzilla.gnome.org/show_bug.cgi?id=773100
discusses the change from three installed libraries (gdk, gsk
and gtk) to one (gtk) with all code from the three directories
gdk, gsk, gtk.
Should we do the same in gtkmm? Skipping (at least not
installing) libgdkmm instead of adding libgskmm, when we start
wrapping classes in the gtk+/gsk directory?
