[boost] Equivalent of "bootstrap.sh --without-libraries" for Modularized and CMake-ified boost

Dear boost@lists.boost.org, I'm trying to use CMake to build boost, using its Modularized and CMake-ified version at: https://github.com/ryppl/boost-zero I need to do the equivalent of --without-libraries=mpi with bootstrap.sh. Any idea if this is possible, and if so how to do it? Regards, -Julien
