Vladimir has stated that he intends
to continue support for Boost.Build
even if Boost itself switches away.
At this point, switching to CMake is
not a done deal, anyway.

You should be able to do this with
any build system. Boost.Build
supports this directly. For CMake,
depending on the backend, you can
use separate build directories for each
