Create a new message ROS2 Dashing
I am not able to create a ROS2 Dashing new message, in spite of the fact that I have followed properly this small tutorial https://index.ros.org/doc/ros2/Tutori.... It seems to be prepared for older distributions such as ROS2 Crystal, but in this case I always find an error related with rosidl_cmake and member of group tag when trying to compile the workspace.
Could you help me?
