tqtinterface and tqt build without opengl issue

Hi I run into an issue when building tqt and tde without opengl. The build of tqtinterface fails with: === In file included from /var/tmp/portage/dev-qt/tqtinterface-9999/work/tqtinterface/qtinterface/interface_tqt3/tqgl.cpp:23:0: /usr/tqt3/include/ntqgl.h:83:21: fatal error: GL/glu.h: No such file or directory # include <GL/glu.h> === As you can see it because GL/glu.h is not present on the system (which should be ok for non-opengl build). I don't want to add yet another build time dependency only because of excess header which doesn't needed to produce any code... AFAIK most of cpp files under the tqtinterface produce any useful code so they may be safely removed only slightly changing the cmake files... What do you think about both the issue and future of the tqtinterface? PS: As I can see tqtinterface is a just a legacy by now, so may be it's better to rid of it completely?
