#47 GLE doesn't compile with Qt 4.8
GLE 4.2.4 doesn't compile with Qt 4.8.0 with the following error:

This happens because the GLU dependency was removed from Qt since 4.7 (see http://qt.gitorious.org/qt/qt/commit/e7eed096a0c33607a7a37baaf06e5952dc9d556b/diffs\).
It should be included in 3dviewer.cpp and somewhere in *LIBS explicitly.

Proposed patch
Dear Anton,
Thanks for the patch.
I will make a release with this fix soon. (I also noticed the problem after upgrading to Fedora 16.)
Best Regards,
Jan
This has been fixed in 4.2.4b.
