In the proposed approach the files will copy every time "foo" links,
and "foo" will re-link whenever the "z" library for the current
config changes.

In general though it does not hook up the dependencies directly.
You'll still need to look at adding generator expressions to
OUTPUT and DEPENDS for that.  Note that to handle different
names per-config you can do something like

 $<$<CONFIG:Debug>:debug>$<$<NOT:$<CONFIG:Debug>>:release>
