Problems building boxes opengl 2.0 example on msvc++

[bagheraa]

Hello,
I'm trying to build the boxes example on QtCreator, linked to msvc 9.0 on windows 7 64 bits.
But in the compile stage, it gives me the error:

C3861: 'gluPerspective': identifier not found

I suppose it means I have miss a library, but I don't know what.
Please, can you help me?
