openmpi or mpich2 (mpi)
libjpeg, libpng, zlib, libtiff (gil)

That would be useful indeed. Note however that not all of these
dependencies are needed at build-time (some are header-only libraries,
so the dependency needs to be met by the boost user, not necessarily the
person who builds and packages boost.
Also, I'd be curious how this is dealt with by the conan packaging
logic. I would expect it to be best to pull this kind of information
from project-specific metadata, such as the meta/libraries.json file.
Rene, can you comment on how this is done there ?
