MS used to have this option in vs 6, and it was removed.  My guess is it 
caused too much trouble with upgrades to the compiler, and the command 
line use of the tools is discouraged a bit by the MS developers, I do 
not think it will ever come back as an option.  So, I really don't think 
this is a CMake problem, or something that can be solved by CMake...
