The following is a useful extension on top of your patch. Otherwise,
with --enable-opengl is reported libGL as "missing".

You can find it as 32d9ceac46 in git://git.cinelerra.org/j6t/cinelerra.git
(branch configure-patch).

Subject: [PATCH] List items that were not checked as "not probed" rather than "missing"

When --enable-opengl is used, then libGL is not checked for, and with
the recent commit, it was reported as "missing", even though the OpenGL
component was enabled.
