Looking for Makefile learning materials

Hi, all VEX enthusiast.

Recently I contact with Pros, and find a huge knowledge gap in Makefile.
I used to program on Windows System, and I never heard about how to Makefile.
Specifically how to makefile in Pros.

So I want to consult how do you guys learn about Makefile.

Where you looking to make a new project in pros?

A Google search reveals several websites documenting makefiles and how to work with them:
