you need cmake and gcc, ninja is optional but recommended windows only btw, should probably work on wine? i don't have as 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.
