Intended way of including python libraries (frozen) in the build...

[synco]

Hello,
I've compiled micropython for the ESP32 on custom hardware, and would like to select (include + remove) some of the frozen packages built into the image.
I have been copying the desired .py files from the micropython/lib/micropython-lib/ into my /micropython/ports/esp32/modules/ directory, and it works perfectly well. (ie, they get compiled as *.mpy and included in the image)
It just feels a bit wrong, and wondering what is this the proper/intended way?
And how do you remove unwanted drivers / libraries?
Are the manifest files used for this?
Thanks in advance.

Are the manifest files used for this?

Yes. The idea is that you can write your own manifest.py (which lives outside the main repo, in your own repo ideally) and then pass that to the build with make BOARD=... FROZEN_MANIFEST=...path....

Your custom manifest is free to use any of the base ones by include()-ing the port or board manifests.

The next step up is to define your own custom board definition (which sounds like might be useful to you if you're building a custom board) which lets you configure much more (via a custom mpconfigboard.cmake and mpconfigboard.h). These also can live in your own repo. See https://github.com/micropython/micropython-example-boards

(This is a bit of an FAQ, and we really need to write more documentation on this process...).

@synco you can add subdirectory on '/micropython/ports/esp32/modules/' too:

i have compiled mpy to include aioble library.i added these files to modules:

/micropython/ports/esp32/modules/aioble/central.py
/micropython/ports/esp32/modules/aioble/client.py
/micropython/ports/esp32/modules/aioble/core.py
/micropython/ports/esp32/modules/aioble/device.py
/micropython/ports/esp32/modules/aioble/l2cap.py
/micropython/ports/esp32/modules/aioble/peripheral.py
/micropython/ports/esp32/modules/aioble/security.py
/micropython/ports/esp32/modules/aioble/server.py
/micropython/ports/esp32/modules/aioble/__init__.py

help('modules') output:
