How to inherit gazebo_ros2_control::GazeboSystem(gazebo_hardware_plugins) elegantly?

[CaptainKAZ]

Hi I want to write a plugin to expand default hardware plugin (gazebo_ros2_control::GazeboSystem)
So I #include <gazebo_ros2_control/gazebo_system.hpp> and inherit the origin class like this class GazeboXXXExpandedSystem : public gazebo_ros2_control::GazeboSystem and then override read and write function to make my own behaiver
Question is, when I compile my plugin, the compiler throws error that classgazebo_ros2_control::GazeboSystemPrivate declared in gazebo_system.hpp is undefined.
At last I have to copy the whole definition of gazebo_ros2_control::GazeboSystemPrivate into my src make the compiler happy.
Is there any way I can do this more elegantly?
