Plugin issues with Gazebo 11

[Prasanna-icefire]

On following the steps with arducopter, the gazebo world opens up with out a drone in it.
On ardurover the rover does load in the gazebo world but, I receive this:

[Err] [Plugin.hh:178] Failed to load plugin libhusky_gazebo_plugins.so: libhusky_gazebo_plugins.so: cannot open shared object file: No such file or directory
[Err] [Plugin.hh:178] Failed to load plugin /home/icefire/Drone/ardupilot_gazebo/build/libArduPilotPlugin.so: libgazebo_sensors.so.9: cannot open shared object file: No such file or directory

Hi,
For the first error message, you can ignore the first error
[Err] [Plugin.hh:178] Failed to load plugin libhusky_gazebo_plugins.so: libhusky_gazebo_plugins.so: cannot open shared object file: No such file or directory

For the second error message, cannot be ignored. It seems you have gazebo 9 installed in your system and built plugin for gazebo 9 not for 11
