 Clone and build kuka-external-control-sdk in a different workspace.
  - This library is necessary for the iiQKA ExternalAPI.Control driver
  - The library is not a ROS2 package, therefore a different workspace is necessary, otherwise colcon will fail to build it
+ - To install dependencies for your platform, check out the [Requirements](https://github.com/kroshu/kuka-external-control-sdk/blob/master/kuka-external-control-sdk/doc/SDK_howto.md#requirements) section of the kuka-external-control-sdk documentation.
