 Subject: [PATCH] demos: makes opengl an optional component
 
 This patch is a port of [1] for the new meson build system.
 
+matrix-code from es2gears has been moved to util in version 9.0.0 [2]
+so now es2gears is linked with mesa3d-demo libutil (idep_util).
+But at the same time the dependency on glu (dep_glu) has been added
+to libutil [3]. dep_glu requires opengl (FULL_GL) to build.
+
+In order to keep the es2gears for egl only builds we have to
+split the libutil files list to build readtex.c and showbuffer.c
+only if opengl is available.
+
+Add back dep_glu since it's used in util's meson.
+
+Fixes:
