Ok, so I tried to build chocolate doom as well (on Debian WSL): $ git clone --depth=1 https://github.com/chocolate-doom/chocolate-doom https://github.com/chocolate-doom/chocolate-doom $ cd c*doom; ls Ok, there is a CMakeFile.txt, so it's probably a cmake project, so: $ cmake . Ok, that seems to work, but three libraries are missing, SDL2_Mixer, SDL2_Net and FluidSynth, so lets install them: $ sudo apt install libsdl2-mixer-dev libsdl2-net-dev libfluidsynth-dev Let's try again: $ cmake . Works, so now for compiling: $ cmake --build . -j $(nproc) Build completed in a few seconds first try.
