I was thinking of the case where a library is built out of tree but there does exist a complete Boost source tree and BOOST_ROOT (from the environment, for instance) points to it. Some libraries seem to support that, at least in theory judging by their Jamfiles.
Although now that I think of it more, this case probably doesn't translate well to CMake.
