Not able to Build the firmware.

[mohankaushik97]

•	Hardware description: ESP32-S3 (Xtensa architecture), MacBook M4
•	RTOS: FreeRTOS (from ESP-IDF)
•	Installation type: micro_ros_setup via ESP-IDF component (micro_ros_espidf_component) jazzy branch
•	Version or commit hash: ESP-IDF v5.5.1, micro-ROS Jazzy

Steps to reproduce the issue

1. Set up ESP-IDF v5.5.1 (. $IDF_PATH/export.sh)

2. `pip3 install catkin_pkg lark-parser colcon-common-extensions`
   

3. Create a new micro-ROS app using the ESP-IDF template
4. Run the following build command inside the project directory:
   idf.py set-target esp32s3
idf.py build
5. Observe build process failing during colcon build in the ament_cmake_core stage

Expected behavior

The micro-ROS client library should build successfully within the ESP-IDF build system, completing the colcon build process for the micro_ros_dev folder without dependency errors.

Actual behavior

Build Fails with:
ModuleNotFoundError: No module named 'catkin_pkg' CMake Error at cmake/core/ament_package_xml.cmake:95 (message): execute_process(...) returned error code 1

Speculation: have you done source ~/esp/v5.2.5/esp-idf/export.sh before running pip3 install catkin_pkg lark-parser colcon-common-extensions?

If not, those dependencies end up in site-packages for your workstation, not for your ESP-IDF installation which has its own python interpreter. In my case, I have a .espressif/python_env/idf5.2_py3.12_env/bin/python3 interpreter and it uses packages installed in .espressif/python_env/idf5.2_py3.12_env/lib/python3.12/site-packages.

After running export.sh, your python3 command will be the one in ~/.espressif/python_env/idf5.2_py3.12_env/bin/python3

[mohankaushik97]

I do source the IDF environment before installing the packages.

Speculation: This might be because I'm trying to build this on my Mac, which does not have ROS2 installed.
