It would be neat if all build systems had a standardized way to return their dependency graph (like gcc -MD) so they can be used recursively by other build systems. I'm not aware of any that does and there's far from a standard which allows easy chaining of multiple different sub build systems. Which unfortunately either leads to recursive make, remodeling the dependencies in two places or forcing everything into the same build system.
