Can't build on Windows

Most likely you are building under the default "Debug - LLVM" configuration, which has some issues. Change the configuration to "Debug", "Release" or "Release - LLVM".

Alternatively, you can fix the issues on "Debug - LLVM" by:
1. Adding the `/bigobj` option under the project: VKGSRender -> Properties -> C/C++ -> Command Line -> Additional Options (as you already did).
2. Adding the `gdi32.lib` library under the project: rpcs3 -> Properties -> Linker -> Input -> Additional Dependencies.
