Don’t know if this is it but try doing a clean configure. I find with MSVC projects that if you don’t, some settings get reset any time a change is made to CMake.

I wish I understood CMake.
The CMakeCache.txt file clearly says
> //Flags used by the compiler during all build types.
> CMAKE_CXX_FLAGS:STRING= /DWIN32 /D_WINDOWS /W3 /GR /EHsc
> //Flags used by the compiler during all build types.
> CMAKE_C_FLAGS:STRING= /DWIN32 /D_WINDOWS /W3
and yet the VS project has it as
> Warning Level Level4 (/W4)
So possibly a bug in CMake or possibly something I am not seeing.
Any ideas?

The same is true with mingw and under Linux and OSX, but neither gcc nor clang have any warnings. What is an example of such a warning?
The relevant warning in Xcode is 'Implicit conversion to 32 bit type' a.k.a GCC_WARN_64_TO_32_BIT_CONVERSION = YES
but this is not enabled by default in the configuration that CMake creates. The corresponding warning(s) are enabled for MSVC.
I'll investigate /W3 on Windows, too.
