+Subject: [PATCH] meson: fix glx-detection without glvnd
+
+When build without GLVND, Mesa provides GLX as a part of libGL, just
+like XQuartz does on MacOS. There's nothing really macOS specific about
+this fallback, so let's drop the condition.
+
+And just for good measure, let's add in dep_gl as a dependency for
+the header-check here, in case some one decides to install libGL outside
+of the default include directory.
+
+Fixes: 34300551 ("meson: explicitly check for glx dependency")
+Closes: https://gitlab.freedesktop.org/mesa/demos/-/issues/36
