Hi everyone: when i use the code below: oid cloud_cb(const boost::shared_ptr<const sensor_msgs::pointcloud2="">& input){

pcl::PCLPointCloud2 pcl_pc2;
pcl_conversions::toPCL(*input,pcl_pc2);
pcl::PointCloud<pcl::PointXYZ>::Ptr temp_cloud(new pcl::PointCloud<pcl::PointXYZ>);
pcl::fromPCLPointCloud2(pcl_pc2,*temp_cloud);
//do stuff with temp_cloud here
}

i got the error:

error USE_ROS setup requires PCL to compile against ROS message headers, which is now deprecated

what it means, thanks?
