I think it'll work as follows: on the first run, the cache is empty,
and no paths are present. The makefile will be generated, and the
cache will be updated with the paths. Next, when the user runs "make",
it detects that the cache has been updated, and regenerates the
makefile. At this point, all the library destinations are known (from
the initial makefile generation phase), so the paths can still be
extracted.
