Add compontent.mk for esp-idf

I'm trying to use this in a project in esp-idf with ardunio-esp32 per:

https://github.com/espressif/arduino-esp32/blob/master/docs/esp-idf_component.md

This is my main.cpp file that is loaded by the arduino-esp32 component:

#include "Arduino.h"
#include "esp_camera.h"
#include <AWS_IOT.h>

void setup(){
      Serial.begin(115200);
}

void loop(){
      Serial.println("loop");
        delay(1000);
}

As is I get an error importing AWS_IOT.h:

fatal error: AWS_IOT.h: No such file or directory

If I add component.mk (below) to the root of esp32-aws-iot then AWS_IOT.h is found and everything works.
