you need cmake and gcc, ninja is optional but recommended (you also need ffmpeg in your path or next to the exe if you want looped audio)
windows only btw, should probably work on wine? i don't have a linux install anymore so can't test.
do uhhhh
mkdir build
cd build
cmake .. -G Ninja -DCMAKE_BUILD_TYPE=Release
ninjathen the exe should exist at build/noteamountgen_gui.exe
this uses sightread by gms to parse charts, modified version is included to remove the boost dependency since we don't need qbmidi support.
