How to create and build an ESP-IDF static library?

Question

I'm learning ESP-IDF platform and now want to create a library in order to be able to structure my code properly in the future.

I've done some research and found few things, for instance a library that could be as an example. The only issue with it being too large, I can't clearly see what's the bare minimum for the simplest library code.

What is the minimum configuration for an ESP-IDF static library that can be built into a .a file?

A minimal ESP-IDF component would have an empty component.mk file, C/C++/ASM source file(s), and header file(s) in include subdirectory. At build time, all source files of the component will be compiled and then linked into a static library, which can be found in build/component_name/libcomponent_name.a. This is further explained in ESP-IDF build system documentation.

There are a few such simple components in the ESP-IDF itself, e.g. log.
