Bug 261654: x11/libinput: enabling DEBUG_GUI fails to build
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D261654



--- Description ---
Enabling DEBUG_GUI option in x11/libinput fails to build.
Requiring wayland and wayland-protocols as the attached patch makes it buil=
d,
but I am not sure if it is the right solution.

1) libinput-debug-gui.c
=20
https://gitlab.freedesktop.org/libinput/libinput/-/blob/e9ccd4f402a8b56590a=
cc83
009f4045b145587bf/tools/libinput-debug-gui.c
  includes "pointer-constraints-unstable-v1-client-protocol.h" when
GDK_WINDOWING_WAYLAND is defined.
2) GDK_WINDOWING_WAYLAND is defined in
/usr/local/include/gtk-3.0/gdk/gdkconfig.h without any condition.
  I did not verify but is it because I enabled WAYLAND in x11-toolkits/gtk3=
0?
3) libinput's meson.build
=20
https://gitlab.freedesktop.org/libinput/libinput/-/blob/e9ccd4f402a8b56590a=
cc83
009f4045b145587bf/meson.build
  only provides "pointer-constraints-unstable-v1-client-protocol.h" when
wayland-client and wayland-protocols are found.

What I am not sure is: is GDK_WINDOWING_WAYLAND in gdkconfig.h is always
defined? Isn't it defined only when option WAYLAND is enabled in
x11-toolkits/gtk30? Then how do I detect it in x11/libinput's port Makefile?
