Why did you change the extension?

Hm.  I don't understand what you want to do.  You have a bunch of .h
files, and you have some C source files which include some .hh files.

That is not related to make variables; your compiler cannot see make
variables while it's compiling.

You have to either change your code to include .h files, or else write
some make rules to create .hh files.  That would involve some kind of
copy command or something.  It can't be done entirely inside make with
just variables, since the compiler needs to actually find the
other-named files in your directory.  Someone or something has to create
those files.
