The mav_msgs library created in rotors_gazebo_plugins isn't linked to a few of the libraries that use it and also it is not installed. This MR fixes that stuff. I also changed the name of the library to mav_proto_msgs bc mav_msgs is the name of a package and it is a bit confusing(at least it was to me reading through it) having a library given the same name as a package being depended upon.

This fixes this issue

Can one of the admins verify this patch?

Thanks for the fix,

Although renaming the package is problematic, since this package is being deployed with the ROS build farm. (e.g. ros-melodic-mav-msgs)

rotors_gazebo_plugins/CMakeLists.txt
# point forward.
# NOTE: This is deprecated, should be using target_link_libraries instead
link_libraries(mav_msgs)
add_library(mav_proto_msgs SHARED ${PROTO_SRCS})

Could you not rename the package? This would need to propagate further than just this cmake file.

This doesn't rename a package. It renames the cmake library created for the protobuf msgs

Just to clarify, the changes here do not rename a package. The CMakeLists.txt was already such that there was a cmake library with the same name as a package being depended upon. This was confusing to me and i'm surprised it didn't cause any errors/warnings. The change here renames the library which is then linked to other targets.

I saw another MR was merged so I pulled master. I also changed how I was fixing the linking issue by just appending the missing proto libraries to the target_linking_LIBRARIES list which made fixing these issues much cleaner. Let me know if there's anything else I can do to get this merged. Thanks!
