An OpenGL game framework/engine

Building

Required system libraries:

• SDL2
• Bullet
• GLM
• Glew (for core OpenGL profiles)

After aquiring these fine softwares, you can build the engine as a normal
CMake-based library. On linux:

git clone --recurse-submodules "https://github.com/grend3d/grend"
mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX=<prefix> # or no prefix for global installation
make && make install

Which you can then link against, see

for an example of how to build against it.
