fatal error: gazebo/gazebo.hh: No such file or directory

edit

Hey, I want to add a gps sensor on my robot. Initially i tried adding the gps sensor in the urdf.xacro file, but no much luck there. So I thought to create a .cpp file as i found by hector_plugins. But when im trying to compile the c++ file i get the following error

fatal error: gazebo/gazebo.hh: No such file or directory
 #include <gazebo/gazebo.hh>
          ^~~~~~~~~~~~~~~~~~
compilation terminated.

When I'm doing the plugin_tutorials everything works perfectly, but when I try to compile it with my files i get the above error. My aim is to extract data about the x,y,z position of my rover.

My cpp code:

#include <functional>
#include <gazebo/gazebo.hh>
#include <gazebo/physics/physics.hh>
#include <gazebo/common/common.hh>
#include <ignition/math/Vector3.hh>

namespace gazebo
{
    class ModelPush : public ModelPlugin
        {
            public: void Load(physics::ModelPtr _parent, sdf::ElementPtr /*_sdf*/)
            //Store pointer to model
            this->model = _parent;

            //Listen to update event. This event is broadcast every simulation iteration
            this->updateConnection = event::Events::ConnectWorldUpdateBegin(
                    std::bind(&ModelPush::OnUpdate, this));

        }

        //Called by the world update start event
        public: void OnUpdate()
        {
            //Get x,y,z position
            this->model->GetWorldPose();
        }

        //Pointer to the model
        private: physics::ModelPtr model;

        //Pointer to the update event connection
        private: event::ConnectionPtr updateConnection;
        };

        //Register plugin with simulation
        GZ_REGISTER_MODEL_PLUGIN(ModelPush)
}

And to compile it i added these two lines in the CMakeLists.txt

add_executable(xyz_push src/xyz_push.cpp)
target_link_libraries(xyz_push ${catkin_LIBRARIES})

Any help will be appreciated. Thanks in advance!
