Using BOOST_ROOT is more for refining how boost is found when multiple version exists in the CMAKE_PREFIX_PATH. So if you install all your dependencies(ie boost, openssl, zlib, etc) in some directory say C:\deps32 and C:\deps64 then all you need to do is set the CMAKE_PREFIX_PATH for each version:

On Windows?

This assumes the build dirs have been created and populated already doesn't it?
It still seems quite cumbersome.
