I want to use the ros2_grasp_library. But I’m a bit confused about the requirements of this Library.

However i tried to install it anyways. I’m using ROS2 Humble and MoveIt2 on my Ubuntu 22.04.
There i created a new folder ~/workspace/pick_and_place_ros_ur/src where i cloned the github repository to.
When i try to build it i get following error:

colcon build --base-paths src/ros2_grasp_library/grasp_apps/fixed_position_pick
Starting >>> fixed_position_pick
--- stderr: fixed_position_pick                         
CMake Error at CMakeLists.txt:35 (find_package):
  By not providing "Findrobot_interface.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "robot_interface", but CMake did not find one.

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


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

My Universal_Robots_ROS2_Driver is in ~/workspace/ros_ur_driver.

Do i need to install the library to a different location?

What requirements do i need to run this library?
In the issues sections, there are some unanswered questions about the UR_Driver, MoveIt Version, ROS2 Version.
