GNU Make does not have a function for doing this sort of regexp-based
modifications, so you are left with using patsubst to get what you want.

You could do:

    files_path := $(patsubst /Module_%,%,$(files_path))

that will eliminate the /Module_ part, and then you'd be forced to do:

   files_path := $(patsubst Test1/%,%,$(files_path))

to remove the Test1/ part, and so on.
