Please keep the mailing list on the CC line, thanks!

As I mentioned in my previous email, there are plenty of ways to
explain to make that a file it may think is intermediate, is actually
not intermediate.  Based on your original request I wasn't sure if that
was what you wanted to do, or if it was something different.

Any file which is mentioned explicitly as a target or a prerequisite in
the makefile is not considered to be intermediate.  So, if you have a
file "foo.bar" that you want to be considered not intermediate: you can
simply add it is an explicit prerequisite anywhere.  This could be your
normal "all" target:

  all: some other files foo.bar

or it could be some completely different target that is not even built

  force_this_not_intermediate: foo.bar

See https://www.gnu.org/software/make/manual/html_node/Chained-Rules.html
where it says:
