[Jazzy/Humble] `UserWarning: Unknown distribution option: 'tests_require'`

[d-kleine]

On Windows using the pre-built binaries for Isaac Sim 6.0.1, when running pixi run build in the jazzy_ws, the build returns following warning multiple times:

UserWarning: Unknown distribution option: 'tests_require'

Affected files in this workspace (jazzy_ws) are

IsaacSim-ros_workspaces/jazzy_ws/src/isaac_compressed_image_decoder/setup.py

Line 34 in dd3eeed

tests_require=['pytest'],

IsaacSim-ros_workspaces/jazzy_ws/src/navigation/isaac_ros_navigation_goal/setup.py

Line 38 in dd3eeed

tests_require=["pytest"],

This seems to affect the other workspace (humble_ws) too:

IsaacSim-ros_workspaces/humble_ws/src/isaac_compressed_image_decoder/setup.py

Line 34 in dd3eeed

tests_require=['pytest'],

IsaacSim-ros_workspaces/humble_ws/src/navigation/isaac_ros_navigation_goal/setup.py

Line 38 in dd3eeed

tests_require=["pytest"],

The issue roots in setuptools that has removed the test command with 0.72.0:
https://setuptools.pypa.io/en/stable/history.html#v72-0-0

but the ROS 2 WS use a higher setuptools version for some setups, e.g. setuptools >=30.3.0,<80. In my case (Windows 11, Isaac Sim 6.0.1, jazzy_ws), pixi list returns setuptools version 79.0.1 has been installed.

Consequently, the setup finishes with the following output:

2 packages had stderr output: isaac_compressed_image_decoder isaac_ros_navigation_goal
