+Subject: [PATCH] use PKG_CHECK_VAR for defining WAYLAND_PROTOCOLS_DATADIR
+
+This allows to override the wayland-protocols pkgdatadir with the
+WAYLAND_PROTOCOLS_DATADIR from environment.
+
+pkgconfig would return an absolute path in /usr/share/wayland-protocols
+for the pkgdatadir value, which is not suitable for cross-compiling.
