Git Submodules... this?
<https://git-scm.com/book/en/v2/Git-Tools-Submodules>

I'm not seeing anything there about build processes.

And if I understand the "conditional prerequisite" idea, it means that 
someone could have a system without software for doc builds such as 
extractpdfmark, and still run "make" with no issues about that. But if 
they did "make doc" it would respond with some form of "Need some more 
dependencies first."

What would Git Submodules offer for that?
