If you're comfortable with maintaining the dependencies where they are
needed I would recommend doing it the way you were planning on and use
Boost_<COMPONENT>_LIBRARY, it also handles the debug/optimized links for
Visual Studio.  I only mentioned Boost_LIBRARIES so you knew it existed and
a partial theory as to why this documentation bug probably hasn't cropped up
on the mailing list before.  There actually are a couple of good reasons not
to use Boost_LIBRARIES (linking time would in theory be faster, if done
correctly you would know at a glance which libraries of yours depend on
which boost libraries).

That being said most people probably don't really care. :)
