Certainly I was unaware that CMake supports multiple configurations at
once[1], so there might be assumptions lurking.  Based on a search for
CMAKE_BUILD_TYPE, I can only see one problem (other than naming), where
we conditionally set D3D_DEBUG_INFO.  But CMake already supports
defining different symbols for different build types so it is easily
fixed.

If I my understanding of CMake is correct, conditions using CMAKE_BUILD_TYPE should not be affected by altering CMAKE_CONFIGURATION_TYPES:

1. CMAKE_CONFIGURATION_TYPES is just a list of possible CMAKE_BUILD_TYPES to choose from.
2. When selecting a configuration from MSVC, you are essentially "dynamically" selecting the CMAKE_BUILD_TYPE

Therefore D3D_DEBUG_INFO will still be set correctly for each configuration..
