C++ ECS Game Engine using OSG and CEGUI. Implementations of several ideas from Game Coding Complete, Game Programming Gems and others.

Just set the correct paths to OpenSceneGraph and CEGUI in CMakeLists.txt, hit cmake && make, and the thing should compile. Note that those are only libraries. Then, to install: sudo make install (make sure to check CMakeLists.txt to setup the install path).
