Elixir CRC will not compile on MAC OS - erlang

Question

My elixir project indirectly uses crc which has NIFs. They won't compile. It look like the linked does not see the libraries.

You need to have gcc and make installed. Try running the
commands "gcc --version" and / or "make --version". If these programs
are not installed, you will be prompted to install them.
I proceeded to check the env:

This is most likely configuration issue. I will post minimal reproducible project though

You need to install erlang development libraries, where this _enif_*** family of functions is declared.
On Debian Linux:
through Erlang Solutions — preferrable
using distro repo: sudo apt install erlang-dev
For MacOS, Erlang Solutions provide the ancient OTP version 19.3 only, I have no idea whether brew provides the latest OTP. If it does, do brew install erlang-r23-dev or like. If it does not, you are probably in a position to compile erlang yourself.
NB please refer to the very valuable comment below to see how to teach MacOS there is dev version already installed.
