You should just need to define CMAKE_PREFIX_PATH as that is the variable you use in cmake to tell it where dependencies are(even on windows). 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:

alias cmake32=‘cmake -G \'Visual Studio 14 2015\' -DCMAKE_PREFIX_PATH=C:\deps32 -DCMAKE_INSTALL_PREFIX=C:\deps32’ alias cmake64=‘cmake -G \'Visual Studio 14 2015 Win64\' -DCMAKE_PREFIX_PATH=C:\deps64 -DCMAKE_INSTALL_PREFIX=C:\deps64’

Then cmake32/cmake64 sets up cmake with the different address models, and there is no need to worry about setting custom variables such as BOOST_ROOT. You just create separate build trees for each variant instead.

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

There is no need to cd into each build directory. The `--build` flag takes the build directory, and like I showed in another email, you can build everything all in one go with: ls -1 | xargs -n1 -I {} cmake --build {} --config Release Or you could do: alias b='ls -1 | xargs -n1 -I {} cmake --build {} --config Release’ So all you have to type is `b` and it builds everything in one go.
