Unable to build libmicroros.a correctly

[lishuai-cau]

I use docker and esp idf v4.4 to make micro_ros humble branch, but it build failed.
I use the following steps：

  . $IDF_PATH/export.sh
  pip3 install catkin_pkg lark-parser empy colcon-common-extensions
  idf.py set-target esp32
  idf.py build
The error message displayed is as follows：

This is a known issue, please check: colcon/colcon-python-setup-py#56

Also:

Pinning setuptools==68.1.2 fixed this issue temporarily but doesn't fix the root cause.
