Unable to compile examples

• ESP32 Thing Plus
• Installation type: simply following the build instructions
• Version or commit hash: galactic, humble, or main all tried.

ESP-idf version 4.2 username@dev0:~/esp-idf$ git checkout v4.2 HEAD is now at c40f2590bf Merge branch 'featrue/remove_esp32-S2_preview_v4.2' into 'release/v4.2'

Either with or without clean build env per install instructions:

"If you encounter issues during the build process, ensure that you are running in a clean shell environment _without_ the ROS 2 setup script sourced."

Steps to reproduce the issue

First try with "clean shell environment" Simply follow the instructions on a fresh Ubunutu 20 install. https://github.com/micro-ROS/micro_ros_espidf_component/blob/galactic/README.md?plain=1#L35 leads to:
