Linker error if package is built from source and installed through apt

[RobertWilbrandt]

When building ur_robot_driver (ROS2, humble) with this package from source, it fails if i also have ros-humble-ur-client-library installed. The error is:

/usr/bin/ld: /home/wilbrandt/robot_folders/checkout/ur_humble/colcon_ws/install/ur_robot_driver/lib/libur_robot_driver_plugin.so: undefined reference to `urcl::UrDriver::UrDriver(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::function<void (bool)>, bool, std::unique_ptr<urcl::ToolCommSetup, std::default_delete<urcl::ToolCommSetup> >, unsigned int, unsigned int, int, double, bool, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, unsigned int, unsigned int)'
collect2: error: ld returned 1 exit status

I am not yet sure if this is an error in this package or somewhere in the build system.
