bcp --boost=boost-root-directory boost/test output-path

You still get a lot of dependencies - including chrono and system which
are pulled in from libs/test/build/Jamfile.v2 via a dependency on
Boost.Timer.  Most of the extra dependencies are created because bcp
follows every conceivable preprocessor path - so get dozens of
dependencies only required by broken compilers etc.

HTH, John.
