Yes but the OP was asking what to set so the _compiler_ can find those
files.


That's a function of your compiler, and not at all related to make.
Typically you would add -I<somepath> to your compile line, and that
means modifying a make variable that contains options provided to your
compiler.


Without knowing anything about your makefile environment there's not
much more we can say.  But please don't send your entire makefile
environment: we're not able to examine/debug something like that.
You'll need to learn enough makefile syntax to be able to ask shorter,
targeted questions.  The GNU make manual is an excellent resource for
learning about makefiles.
