I think we always need compile-time support for X11.

As you mentioned in commit log, PLATFORM(X11) should imply GDK_WINDOWING_X11.
So I think it is better to remove defined(GDK_WINDOWING_X11) from this patch.

We do now, but this patch guards RedirectedXCompositeWindow that won't be used in builds for the Wayland target.

OK, I'll enhance the CMake system to properly check for dependencies that would make 'PLATFORM(X11)' equivalent to 'PLATFORM(X11) && defined(GDK_WINDOWING_X11)', and then use PLATFORM(X11) only.

Can you talk more about builds that do not support X11, but do support Wayland?

In Autotools we supported building for either X11 windowing target, Wayland windowing target, or both -- much like GTK+ can support different windowing targets. Of course we'll be checking that the GTK+ installation that's used was actually configured to enable the desired windowing target.

The idea is to achieve the same with CMake. I can't really remember though why all these guards that are being added in this patch weren't necessary ~6 months ago.

I'm not sure of the benefit of making this configurable. My proposal is that we just target the same platforms that the GTK+ we are compiling against supports.

That makes sense. Bug 134736.
