Hi

I ran into a little trouble building qwtplot3d. I am building on ubuntu 12.04 / qt5.2, and I got the following error:

anon@ubuntu:/opt/qt5/build/qwtplot3d$ qmake
anon@ubuntu:/opt/qt5/build/qwtplot3d$ make

anon@ubuntu:/opt/qt5/build/qwtplot3d$ gedit include/qwt3d_openglhelper.h

I edited qwt3d_openglhelper.h and added the following #include:

include <GL glu.h="">

... and now it builds ok for me.

Cheers
