There are a few issues here, which I'm trying to resolve:
Bridge Command is set up for 32 bit compilation only for Windows, but VS2017 defaults to the x64 configuration, which isn't set up. This gives the errors about finding irrlicht.h
I will manually remove the x64 configurations from the Visual Studio files, which should fix this.
Separately, I had hardcoded paths to items in the Windows SDK, which I am trying to resolve, but is non-trivial (different windows SDK versions put things in different places). I'll push the updates when complete.
