mupdf requires glu, it is no longer pulled in.

In my jhalfs testing I built firefox, seamonkey, and xfce. Inevitably, that pulled in far more deps than I had anticipated, but right at the end it intended to build cups-filters, and for that it needed mupdf. (Too many items to work out why cups-filters was right at the end, presumably a runtime dep of something).

mupdf failed:

   CC build/shared-release/platform/gl/gl-file.o

That file comes from GLU. In the mupdf instructions we now have:

USE_SYSTEM_GLUT := no # need freeglut2-art fork

Looking at dependencies, freeglut recommended glu. I guess that the dependency has become lost now that system glut cannot be used in mupdf.

I'll start an incremental build in a little while, specifying xscreensaver (which already pulls in GLU) and cups-filters to prove this is the required fix.

Builds ok like that. Looking at the header, glu.h is needed unless FREEGLUT_GLES or APPLE are defined, so required rather than recommended.

(trac interprets the double underscores around APPLE as starting and ending underlining)
