ESP-NOW not being added into IDF as submodule

[Zonda63]

Hello, I've added the ESP-NOW library to IDF with "git clone --recursive https://github.com/espressif/esp-now.git" . I do see the "esp-now" folder in the main directory of esp-idf but upon compiling examples, none of the header files can be located and it throws errors accordingly. Are there other commands I need to use to link the esp-now library? Am using IDF 4.1.

Thank you
