We will use the new command.  It makes backward compatibility almost
trivial.  In an earlier post I explained why include dirs should be
needed for everything in the link closure, but I think that will come
naturally when projects switch fully to target_use_interfaces.

Fine with me.  I've been drafting a new message about how to do the
policy for INTERFACE_LINK_LIBRARIES, the most critical part of this
transition.  Hopefully I'll have it ready to post soon.
