target_link_libraries() links against ${mrs_msgs_TARGETS}, but this CMakeLists.txt never calls find_package(mrs_msgs REQUIRED) (and the code in this package doesn’t appear to use mrs_msgs). As written, CMake configuration will fail due to an undefined variable/target list. Either add the missing find_package(mrs_msgs REQUIRED) + proper linking/export, or remove ${mrs_msgs_TARGETS} from the link list.

Please fix the following when running a tmux session:

• you should be directed straight to the template window
• first window should run the launch.xml so that the second window can start listening
• add the fourth window, so you know you have two services to work with: allow and ban
• fix the launch node name so it matches the changes and services can be called

Test it ;) Also functional changes shouldn't be in refactor README branch :D
