CDGE -> 'Chemical Development Game Engine'
It's a lightweight, object oriented game engine designed for 3D games (and simulations). It also features a 3D sound engine (with directional and delayed sound based on position relative to camera)
You'll need x11 dev and stuff:
sudo apt install xorg-dev for instance
Due to dependencies with different versions, and dynamic linking problems, it is suggested (and much easier) just to build a local static library for all the dependencies locally.
You can use the script
./build_libs.sh to create the
build/ dir and build all dependencies.
