However, I think Visual Studio should be the exception. Since most people except to be able to build 32/64 bit application with visual studio.

It’s a fundamental limitation to CMake. What is the value of CMAKE_SYSTEM_PROCESSOR with two toolchains? CMake would need lots of work to support such a workflow.
