--with-gle Build those demos which depend on GLE
(the OpenGL "extrusion" library.)
--with-gles Target OpenGL ES 1.x API instead of OpenGL 1.3.
+ --with-png Include support for the PNG library.
--with-pixbuf Include support for the GDK-Pixbuf library in some
demos, which will make it possible for them to read
GIF, JPEG, and PNG files as well.
- --with-xpm Include support for XPM files in some demos.
- (Not needed if Pixbuf is used.)
--with-jpeg Include support for the JPEG library.
--with-xft Include support for the X Freetype library.
--with-xshm-ext Include support for the Shared Memory extension.

-# If this is Motif 2.x, and we have XPM, then link against XPM as well.
-# The deal is, Motif 2.x requires XPM -- but it's a compilation option
-# of the library whether to build the XPM code into libXm, or whether
-# to rely on an external libXm. So the only way to tell whether XPM is
-# a link-time requirement is to examine libXm.a, which is very
-# difficult to do in an autoconf script. So... if it's Motif 2.x, we
-# always link against XPM if the XPM lib exists (and this will be a
-# no-op if libXm happens to already have the XPM code in it.)
