Unable to build the project when using FreeRTOS in own Cmake project for ESP32

I was successfully able to build and run the AWS demos (MQTT, OTA, BLE) but unable to build the custom project example using Freertos for both methods (with components and without components). The complete details are mentioned below. I would like to know how to resolve this issue or what could be wrong. If further information is required, please let me know.

Target microcontroller: vendor: Espressif

board: ESP32-DevKitC

Host platform: OS: Ubuntu 18.04.5 LTS

Toolchain: xtensa-esp32

Toolchain path: /home/user/.espressif/tools/xtensa-esp32-elf/esp-2020r3-8.4.0/xtensa-esp32-elf

CMake generator: Ninja

AWS Freertos version: 202107.00

Followed the steps as mentioned in the AWS User guide

Method 1:

For project directory structure

  • freertos (the copy that you obtained from GitHub or the AWS IoT console)

  • src - > main.c (application code)

  • CMakeLists.txt

After executing the command: cmake -S . -B build -DCMAKE_TOOLCHAIN_FILE=freertos/tools/cmake/toolchains/xtensa-esp32.cmake -GNinja

The error obtained is as below

-- The C compiler identification is GNU 5.2.0 

-- The CXX compiler identification is GNU 5.2.0 

-- The ASM compiler identification is GNU 

-- Found assembler: /home/augmented/esp/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc

Hi @ARG3,
is your issue similar to this one CMake project setup issues with AWS FreeRTOS for ESP32
and/or this one
How do I link amazon freertos to my project
If you follow the steps mentioned and it doesn’t work pleas let me know.

Hi
Thank you for the quick response. I tried the solution that you pointed to with the changes in the CMakeLists.txt in the components folder and the one on the top-level.
However I encounter a different error now. Could you please let me know what could be wrong.
