Yes.

Except in the makefile you need to escape the linebreaks in the macro
assignments. Like this:

FOO = something something_else \
	someother yet_morethings \
	last_thing

Once this has been set, it can be referenced in the command lines with
the $() notation.


Make is stormingly complicated and almost no-one can use it properly,
mostly because there are no books that explain how to use it properly
and very few guides. Do a websearch for an article entitled "Recursive
Make Considered Harmful" because it talks about how to do makefiles
properly. It's a bit high level, but it has working examples of things
to look at.
