+Subject: [PATCH] Use packageconfig to detect mmal support
+
+This needs userland graphics libraries, because distros may install it
+in different locations, therefore its best to rely on pkgconf to find
+the libs and header locations instead of assuming /opt/vc which might
+work on some distros ( like raspbian ) but not everywhere
