ESp32 C2 does not compile in linux, but seems to compile in Windows

[zackees]

Hi, I'm a maintainer for FastLED.

I noticed that the ESP32 C2 board does not compile under our test running in linux, but seems to compile just fine on my windows box when running locally.

Here is the repro case
https://github.com/FastLED/FastLED/actions/workflows/build_esp32c2.yml

However I can totally run the command in windows and it works great:

(note that I'm running using git-bash in windows at the root of the FastLED repo)

Okay confirmed, you are missing the esp32-c2-devkitm-1.json file.

You can probably just copy it from here:

https://github.com/zackees/platform-espressif32/blob/Arduino/IDF5/boards/esp32-c2-devkitm-1.json

@zackees There is no C2 supported. See #1347 and #1225

[zackees]

Gotcha. Seems like a complicated political battle.

Hi @zackees, it seems you're using a fork of the espressif32 dev platform, so please forward your issue there.
