Third party dependencies are registered using git submodules, so you will need to either clone with the
--recursive flag, or run
git submodule update --init after cloning.
build.cmd batch file will attempt to build Very Sleepy and its dependencies.
Alternatively, you can build Dr. MinGW using the
thirdparty/drmingw_build_mingw.cmd batch file, then use the Visual Studio solution file (
sleepy.sln) to build everything else.
