Alternatively the option() or set(CACHE) commands could also set a
local variable to the same value as the cache entry.
I would vote for that.
Maybe optional arguments to set(CACHE) could be introduced to switch the
behavior.
Like set(... CACHED ... [UNSET_LOCAL] [OVERWRITE_LOCAL] [KEEP_LOCAL]).
What about locals in parent scopes, overwrite all of them?
Bug https://public.kitware.com/Bug/view.php?id=15448 is kind of related,
and also shows some weird effects of the current implementation.
