Failed to load plugin libhusky_gazebo_plugins.so

edit

Hey,

So i was trying to play around with husky in gazebo using ardupilot. I tried running the code given in the github page of SwiftGust.

gazebo --verbose rover_ardupilot.world

However I keep getting the following error

Failed to load plugin libhusky_gazebo_plugins.so

I checked the ros plugin folder /opt/ros/kinetic/lib/ but didnt find the plugin there. I am not sure how to get the plugin. However I am able to get the husky rover with the command from the husky site

roslaunch husky_gazebo husky_empty_world.launch

Thanks
