Only ubuntu is supported.

CMake v3.24 Ubuntu 22.04 LTS – OR – WSL2 - Ubuntu

Coming Soon.


Unsupported, due to terrible support of Modern C++ and OpenGL.


There are additional helper scripts located in the scripts folder. In order to run these, you require a MSYS2 installation installed on your PATH.


See online documentation.
