The base game-dev code I've been developing on and off since 2015. It is not good but it is mine.

The build uses CMake. I don't know a lot about CMake, so these instructions may be lacking.

Set up the CMake build using something like this:

cmake -DCMAKE_BUILD_TYPE=Debug -G Ninja -B ./Build/Debug

Then compile like this:

cd ./Build/Debug
ninja
