Those headers are used for interoping with various popular C++ libraries. For now, those libraries are Eigen, GLM, HandmadeMath, Raylib, and SFML. Some other ones may be added in the future. Those are disabled by default, as most projects I would imagine would not use them. But in case you need any of them for special reasons like I did, they are there.
