Build problems: CoreLib and AppLib

[scarlettekk]

Hello! I found this project through Hackaday and I'm frankly blown away that this is even possible. I'm trying to build master, and I encounter issues in both Visual Studio, and ninja on Linux. Ninja fails with ninja: error: 'obj/AppLib/GatePix.o', needed by 'bin/AppLib.a', missing and no known rule to make it, and Visual Studio fails to find AppLib and CoreLib, and trying to compile yields errors about that. I see that it appears to be looking for AppLib and CoreLib under src/, when its instead under submodules/MetroLib. What's the proper way of getting this to build?
