The way this usually works is by creating a derived work, which
includes some BSD licensed components and some components of your own,
and then license the whole under the GPL.  Of course, the BSD parts
are still very much licensed under the BSD in this case.

Note that this is not as powerful as with proprietary swallowing of
BSD licensed works: In those cases, all you get is usually the binary,
and there is no requirement to provide either the modified or original
source of the BSD work to anybody.
