build betterRenderer against the modules

Verified locally now that Vulkan and DXC are installed: all 31 targets
compile. glm has to come from eu07.glm only - having it both as a plain
include and as an import made every overload ambiguous. nvrenderer.h is
self-sufficient, since register.cpp includes nothing else. Fixes the
vcpkg triplet, which was pinned to x64-windows.
