How to make another package node get BoundingBox msgs frome darknet_ros

edit

I try to write a node to receive and show data of Bounding Box like below.

#include "ros/ros.h"
#include "darknet_ros_msgs/BoundingBoxes.h"
#include "darknet_ros_msgs/BoundingBox.h"
using namespace std;
void msgCallback(const darknet_ros_msgs::BoundingBoxes::ConstPtr& msg)
{
    cout<<"Bouding Boxes (header):" << msg->header <<endl;
    cout<<"Bouding Boxes (image_header):" << msg->image_header <<endl;
    cout<<"Bouding Boxes (Class):" << msg->bounding_boxes[0].Class <<endl;
    cout<<"Bouding Boxes (xmin):" << msg->bounding_boxes[0].xmin <<endl;
    cout<<"Bouding Boxes (xmax):" << msg->bounding_boxes[0].xmax <<endl;
    cout<<"Bouding Boxes (ymin):" << msg->bounding_boxes[0].ymin <<endl;
    cout<<"Bouding Boxes (ymax):" << msg->bounding_boxes[0].ymax <<endl;
    cout << "\033[2J\033[1;1H";     // clear terminal
}
int main(int argc, char **argv)
{
    ros::init(argc,argv,"cood_subscriber");
    ros::NodeHandle nh;
    ros::Subscriber cood_sub = nh.subscribe("/darknet_ros/bounding_boxes",100,msgCallback);
    ros::spin();
    return 0;
}

I have modify the cmakelist.txt and package.xml

cmakelist.txt

cmake_minimum_required(VERSION 2.8.3)
project(cood_tran)

find_package(catkin REQUIRED COMPONENTS  roscpp  darknet_ros  darknet_ros_msgs)

catkin_package(
#INCLUDE_DIRS include
  LIBRARIES cood_tran

)

include_directories(
  include 
  ${catkin_INCLUDE_DIRS}
)

add_executable(cood_tran src/cood_tran.cpp)
add_dependencies(cood_tran ${${PROJECT_NAME}_EXPORTED_TARGETS} ${catkin_EXPORTED_TARGETS})
target_link_libraries(cood_tran ${catkin_LIBRARIES} )

package.xml:

<?xml version="1.0"?>
<package format="2">

  <description>The cood_tran package</description>

</package>

but when I run catkin_make, these mistakes happen
