esp-tflite-micro: Cannot build the person detection model

Hi guys,

I am trying to build the person detection model, but I always get the same error. I followed the guidelines for installation from the official esp website. Then, in the esp folder I cloned this git repository in order to get the person detection code. After that, I tried to build the example with the command:

idf.py build 

Here is the error that I get every time:

-- Building ESP-IDF components for target esp32

P.S. I am able to run the simple examples from get-started folder and that part works without issues. I am using the ESP32-WROVER-IE board.
