        if(CMAKE_BUILD_TYPE STREQUAL Debug)
            set(D3D_DEBUG_INFO 1)
        endif()

I don't see how that works, unless when you select a Debug configuration
in MSVC, it reruns cmake to regenerate alplatf.h with D3D_DEBUG_INFO
baked in?

Anyway, D3D_DEBUG_INFO shouldn't be set in such a way that it affects
user code.  I'll change it, which should probably fix this problem as
well.  Then you can send a patch to allow the MSVC multi-configurations :)
