The OpenGL packages might have different names on your Linux distribution (I gave the names for Ubuntu).
Psssst. I'm using Ubuntu (I installed KDE on it (Plasma Workspace), and now it's called Kubuntu, magic...).

I did update my apt-get thing.

Qt supports CSS! Who needs C#/XML, get outta mah way! C++/Qt is the king now!
Thanks everybody who contributed. Now I can just look up recent tutorials about C++ and I'm good to go.
