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:

I'd like to build all variants in one go.. having to cd to each build
tree manually is cumbersome.
