There is a world of difference between set() and set(... CACHE ...).
Consult the docs.
What you've done above is set a variable that has nothing to do
with the cache, and in fact will override whatever is in the cache.

In a project configured the way you show in this email, your manually
set variable will always be used; the cache variable will always be
ignored.
