compiz - Apr 2007 - glu dependency

The following commit seems to have added a dependency on glu but does
no checks to see if it is actually available:

    Project vertices and only update minimum required destination texture
    region. Some more optimizations should be done here but the current
    changes should still give a major performance improvement.


My autofoo is very much lacking so I'm not sure how to add such a check.

Problem here is that GLU does not provide a pkg-config .pc file which is
needed to check a libraries availability through configure.ac. libjpeg
has the same problem, BTW.
We could add a check for the header file presence, but I am not sure if
this is a proper solution or is somewhat kludgy.
