Yes there is, run find_library twice, first with NO_DEFAULT_PATH, then
without it. That way the directories that you list are preferred and you
can still easily search the standard system dirs if nothing is found in
the preferred dirs. Works because find_library doesn't search if the
variable it is supposed to fill is already filled with something that
doesn't end in -NOTFOUND.
