I am trying to simulate a drone inside an environment with constant wind. I have found a good plugin (link below) and I have done the following to integrate this plugin in my system:

1. include the gazebowindplugin.cpp file in my src folder
2. include the header file (gazebowindplugin.h) in the include folder
3. edit the CmakeLists.txt to include this plugin

https://github.com/PX4/PX4-SITL_gazebo/blob/master/src/gazebo_wind_plugin.cpp

However, I get errors during catkin_make showing the following:

How do I resolve this physics_msgs issue?
