I am getting undefined reference to pcl_ros::transformPointCloud in the linking phase of catkin_make. This is the source code:

void cloud_cb_cam1 (const sensor_msgs::PointCloud2ConstPtr& input)
{
  cam1_data_valid = true;

sensor_msgs::PointCloud2 ros_cam1;
  pcl_ros::transformPointCloud("pf1_link", input, ros_cam1, tf_listener);
  pcl_conversions::toPCL(ros_cam1, pcl_cam1);


if (cam1_data_valid && cam2_data_valid)
  {
    cam1_data_valid = false;
    cam2_data_valid = false;
    pcl_combine();
  }
}

My CMakeLists includes these libraries:

cmake_minimum_required(VERSION 2.8.3)
project(pc_combine)

find_package(catkin REQUIRED COMPONENTS
  roscpp
  rospy
  std_msgs
)
find_package(PCL REQUIRED)


catkin_package(
)


include_directories(
  ${catkin_INCLUDE_DIRS}
  ${PCL_INCLUDE_DIRS}
)


target_link_libraries( pc_combine
  ${catkin_LIBRARIES}
  ${PCL_LIBRARIES}
)


link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})

Am I missing any libraries?

do you also find_package the PCL library?

Comment by Robpuff on 2016-01-08:
Yes, I use find_package(PCL REQUIRED). I included my entire CMakeLists file Thanks

Your C++ code is using the pcl_ros and pcl_conversions packages, in addition to PCL. You should also include these packages in your list of dependencies:

find_package(catkin REQUIRED COMPONENTS
  roscpp
  rospy
  std_msgs
  pcl_ros
  pcl_conversions
)
