You can actually articulate that relationship in GNU make, as long as your outputs can be coerced into a pattern rule (like "%.c %.h: %.y"). Otherwise there's no way to do it that's reliable in the face of both incremental and full builds. There's been discussion of adding syntax to GNU make for this purpose on-and-off over the past several years, but nobody can seem to agree on what the syntax should be.

With Electric Make you can mark the rule as producing multiple outputs by adding "#pragma multi" above the declaration. See http://blog.melski.net/2013/01/01/pragma-multi-and-rules-wit....
