Building is extremely simple, and it works with both MSVC and Mingw-w64. Clone the git, init the submodules and run cmake. Assuming you're using ninja:
git clone --recursive [insert repo link here] hanteichan
cd hanteichan
mkdir build
cmake -S. -Bbuild -GNinja -DCMAKE_BUILD_TYPE=Release
cmake --build build
build\hanteichan.exe
And that's it!
