Error while sourcing

[Blitzboot]

If i follow the ReadMe i get the following error in the last step:
source install/setup.bash
not found: "/home/user/ros2_ws/install/kuka_external_control_sdk/share/kuka_external_control_sdk/local_setup.bash"
not found: "/home/user/ros2_ws/install/kuka_external_control_sdk_examples/share/kuka_external_control_sdk_examples/local_setup.bash"

kuka_external_control_sdk and kuka_external_control_sdk_examples are not ROS2 (catkin) packages, for which package.xml files were added according to REP136 to support ROS2 tooling.
However the setup.bash files are not created for such packages, which means that everything is working, but the warnings you encounter are displayed, when sourcing. (You would not be able to start executables from this package using ros2 run, but they are only libraries and the libraries they contain can be found by cmake)

Thank you!
Okay so i just ignore this message or can i remove the error?

We could not yet manage to remove the error in a satisfying way, so I would suggest to just ignore it...
