If you install libA as libtool library (i.e., libA.la is installed as
well), then this should work.  libA.la should contain the information
that it depends on libB, that is, if you supplied that at the time of
creating libA.la.

Even if libtool does not state it in its documentation as of now:
If your application directly uses libB (as opposed only through the
use of libA), then you should list libB in the application's link line
as well.  Even if only for documentation purposes.
