[CMake] How to remove _WINDOWS for MSVC preprocessor definitions for library & executable projects?

[Erwin Coumans]

remove_definitions(-D_WINDOWS ) didn't work, possibly because it
wasn't added using add_definitions (but a built-in).

I'm happy with string (REPLACE "/D_WINDOWS" "" CMAKE_CXX_FLAGS
${CMAKE_CXX_FLAGS})
