File missing

When I'm doing catkin_make, this error crops up.
In file included from /home/sambuddha/catkin_ws_2/src/realsense_samples_ros/realsense_ros_person/src/apiwrapper/realsense_ros_person_nodelet.cpp:4:0:
/home/sambuddha/catkin_ws_2/src/realsense_samples_ros/realsense_ros_person/src/apiwrapper/realsense_ros_person_nodelet.h:34:50: fatal error: person_tracking_video_module_factory.h: No such file or directory
#include "person_tracking_video_module_factory.h"

This file is not even present in this github repository. How to debug this error?
