spinny cube
you need the LLVM-MOS SDK to build c64cube.
once you extracted it somewhere, invoke CMake like so:
cmake .. -DCMAKE_PREFIX_PATH=$HOME/.local/llvm-mos
CMake might complain that it couldn't find a make program. if that is the case, add -DCMAKE_MAKE_PROGRAM=$(which make)
to your CMake arguments.
now run make -j$(nproc)
, then load the c64cube.prg
program file into an emulator of choice
