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...). After seeking for OpenGL, I found only the closest ones being: Compiz, Globs, NVidia binary x.org driver, but I don't have Nvidia. There's no such thing in my Ubuntu Software Center. I did update my apt-get thing.
sudo apt-get install freeglut3-dev, I don't know what freeglut3-dev does, it probably will download a whole lots of malware, but frankly I don't care, as long as my application works.
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.
