Error in building create_gazebo_plugins

[ghost]

I am running ROS Melodic on Ubuntu 18.04 and facing the following issue while building with catkin_make_isolated --force-cmake :

Error Output:

I just saw you mentioning me in a post on answers.ros.org, and reading through your question you linked to this bug report. Just wanted to let you know that I recently also had an issue building this package on Melodic/Gazebo 9, and I patched this package in my fork. Perhaps this will get you going. If the maintainers would like me to submit a PR, I'd be happy to do so.
