Found this problem when launching from scratch everything in thre README.

colcon build --cmake-args -DCMAKE_BUILD_TYPE=Release
Starting >>> ur_dashboard_msgs
Starting >>> ur_moveit_config
--- stderr: ur_moveit_config                                          
CMake Error at CMakeLists.txt:4 (find_package):
  By not providing "Findament_cmake.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "ament_cmake", but CMake did not find one.

  Could not find a package configuration file provided by "ament_cmake" with
  any of the following names:

    ament_cmakeConfig.cmake
    ament_cmake-config.cmake

  Add the installation prefix of "ament_cmake" to CMAKE_PREFIX_PATH or set
  "ament_cmake_DIR" to a directory containing one of the above files.  If
  "ament_cmake" provides a separate development package or SDK, be sure it
  has been installed.

probably you never sourced ROS? That's not part of the README, as it is part of installing ROS (see https://docs.ros.org/en/rolling/Installation/Ubuntu-Install-Debians.html#sourcing-the-setup-script). Could you please confirm that this solves your problem? I would be totally fine with including this into the README.
