Libraries for OpenGL

I’ve just been assigned a project at University to make a game and my team and I have decided to make it using C++ OpenGL.
Its a simple side-scroller shooter blah blah - anyway!

I’m having a hard time finding a suitable programming library for OpenGL that can manage 2d textures.

SDL looks wonderful but it uses C, can anyone please give me some advice?

So? C++ can call C code just fine. If you like SDL and it does what you need, use it.
