Arduino as a ESP-IDF component

[raf0x]

Hi,
I'm trying to integrate Arduino as a ESP-IDF component but unfortunately it is not compiling. I've using esp-idf v4.3.1 with arduino-esp32 branch idf-release/v4.4

following error massage is generated

Here is a wrong command - git clone https://github.com/esp-idf-arduino-template. The url should be https://github.com/TheRealDJ/esp-idf-arduino-template
