+# Work around use of obsolete Weston backend-fbdev in meta-rcar-gen3
+# when building without the proprietary driver stack. Masking out the
+# weston_%.bbappend seems the simplest approach for now, as forcing
+# USE_GLES = "1" to disable the adding of -Dbackend-default="fbdev" to
+# EXTRA_OEMESON triggers adding "libgbm" to DEPENDS, which breaks due
+# to that being a component specific to the proprietary stack we are
+# explicitly disabling. If the "libgbm" usage in the bbappend was
+# instead "virtual/libgbm" as is now used in poky, it might be possible
+# to just tweak PREFERRED_PROVIDER_virtual/libgbm = "mesa".
