Help to build esp-idf using arduino as an external component

Hi,
I’m trying to convert an arduino project from here GitHub - ginkage/MHI-AC-Ctrl-ESPHome: ESPHome integration for MHI-AC-Ctrl project to a esp-idf on my esp32 but no sucess so far.
I’ve modified my yaml to this :

esp32:
  board: wemos_d1_mini32
  framework:
    type: esp-idf
    version: latest

Since this file reported to #include <Arduino.h>, I’ve tried to compile it but gives error and can’t manage to add arduino as an esp-idf component like documented here.
https://docs.espressif.com/projects/arduino-esp32/en/latest/esp-idf_component.html

I’ve searched and I don’t know if it is possible in esphome :

Arduino as ESP-IDF component

**Describe the problem you have/What new integration you would like** Arduino can be loaded as a component over ESP-IDF as described here: https://docs.espressif.com/projects/arduino-esp32/en/latest/esp-idf_component.html and here: https://github.com/platformio/platform-espressif32/issues/24 It would be great if ESPHome would allow this configuration: ```yaml esp32: board: esp32dev framework: type: arduino, esp-idf ``` **Please describe your use case for this integration and alternatives you've tried:** I would like to customise the `sdkconfig` compilation flags for ESP-IDF. It would also be useful for people who are migrating their code to pure ESP-IDF. **Additional context** I am trying to set custom pins for the PSRAM built in to the Sonoff NSPanel. It has 16MB PSRAM (see [this link](https://blakadder.com/nspanel-teardown/) for more info), but the pins are non standard, so I need to set these flags: ``` CONFIG_D0WD_PSRAM_CLK_IO=5 # default: 17 CONFIG_D0WD_PSRAM_CS_IO=18 # default: 18 ``` I have tested this using pure esp-idf and I can detect the PSRAM, but Arduino doesn't allow setting these options due to the bootloader being precompiled. The only alternative it to create a custom bootloader using https://github.com/espressif/esp32-arduino-lib-builder but I think esphome wouldn't be able to include this.
