I believe the following log output is relevant to the error: `-- +++ processing catkin metapackage: 'universal_robots' -- ==> add_subdirectory(UR5_With_ROS_Moveit_Tutorial/universal_robot/universal_robots) -- +++ processing catkin package: 'ur_description' -- ==> add_subdirectory(UR5_With_ROS_Moveit_Tutorial/universal_robot/ur_description) -- +++ processing catkin package: 'ur_e_description' -- ==> add_subdirectory(UR5_With_ROS_Moveit_Tutorial/universal_robot/ur_e_description) -- +++ processing catkin package: 'ur_msgs' -- ==> add_subdirectory(UR5_With_ROS_Moveit_Tutorial/universal_robot/ur_msgs) -- Using these message generators: gencpp;geneus;genlisp;gennodejs;genpy -- ur_msgs: 7 messages, 2 services -- +++ processing catkin package: 'robotiq_ethercat' -- ==> add_subdirectory(robotiq/robotiq_ethercat) -- Could NOT find soem (missing: soem_DIR) -- Could not find the required component 'soem'.

CMake Error at /opt/ros/melodic/share/catkin/cmake/catkinConfig.cmake:83 (find_package): Could not find a package configuration file provided by "soem" with any of the following names:

Add the installation prefix of "soem" to CMAKE_PREFIX_PATH or set "soem_DIR" to a directory containing one of the above files. If "soem" provides a separate development package or SDK, be sure it has been installed. Call Stack (most recent call first): robotiq/robotiq_ethercat/CMakeLists.txt:4 (find_package)
