Ryan, You are probably right about the CMAKE_USING_VC_FREE_TOOLS variable.
I guess I don't see a practical case where a developer would go about switching out their development environment - especially going from a paid-for version of the compiler and downgrading it to the express version. On top of that expecting everything to behave as normal and not needing to reconfig CMake. A reconfigure of CMake is trivial and totally within reason. For example, even in the case where you went from MSVC2008 (non-express) and upgraded to MSVC2010 (express) you would still need to reconfigure CMake. Now if the case is about whether it is desirable to have folders there in the first place is in question, then that is a slightly different topic. Then it should be about making that optional irrespective of Express vs. non-Express.
