+Add -DTG_OWT_USE_X11
+
+Allows disabling X11 desktop capturing independently of pipewire support, for
+the few people that run wayland without any X11 support whatsoever.
+
+This setup is untested, but supported by the GNI build system, see:
+* src/modules/desktop_capture/BUILD.gn (option rtc_use_x11_extensions)
+
+Toggling the WEBRTC_USE_X11 define also affects some files under
+src/modules/audio_device, but that falls under "X11 support", regardless...
