How to add some C-modules to omv's micropython?

seeing this topic - How to compile cexample - #2 by kwagyeman . Am I missing smth else?


I’m not a C-programmer at all. I’m inventor. Trying to start big open source project based on omv. Want to try do myself or pass it to the outsource if I could not.
Should it be so easy as find in one of the Makefiles “make” string where I will place my USER_C_MODULE appending or should I search specialists? All my C-libs contains micropython.mk files so they’re prepared to be integrated in mpy with time less than coding directly into mpy.
