ESP-IDF splitting project into multiple files - c

Question

So I'm learning ESP-IDF, moving from Arduino and I was creating my first project and I tried following the docs on creating a component but I'm getting some errors when flashing regarding Pill.c (main c file) not finding the function defined in HomeAssistant.h (component created by me).
Full error:

I'm using Clion as my IDE in case that help in any way.
My question is: Am I missing something or should I do this a different way?
