Micropython Cmake support

[NHTHEBEST]

I tried to compile this for a rpi pico but dint seem to work

Then I tried to port the micropython.mk file to a cmake file but and it complied but did not integrate into micropython

micropython.cmake

[NHTHEBEST]

Managed to compile
Not sure what the issue was
did have to comment some stuff out

@NHTHEBEST your cmake file got me closer (I'm trying to compile for esp32) but the compiler is failing on:

Any tips?

I set up a Docker container configured with all the tools and documented the steps I followed: https://github.com/kdmukai/micropython-esp32

I did get it to compile and run on ESP32. Required some tweaks to secp256k1, secp256k1-embedded, and micropython.

I've forked all of them and will have a complete Docker-based build environment ready to share soon.

@kdmukai How did you get on with this? I am attempting to integrate this into a custom firmware for the badger2040 and I'm getting this same exact error message.

Hopefully it is just a specific thing that needs to be done here?

I can't recall, but look through the commit history of my fork: https://github.com/kdmukai/secp256k1-embedded/tree/75469814bf9ac978236f51b2c509837faed38879
