Book: Learning ROS for Robotic Programming, 2nd Edn; Chapter 6 - pcl_create not working

edit

I am trying to go through the book recommended for the ROS beginners "Learning ROS for Robotics Programming" Second Edition. Right now, I am reading chapter 6 about point cloud library. I have followed all the steps given in there from page 236-240. I am constantly seeing this error

[rosrun] Couldn't find executable named pcl_create below /home/khan/catkin_ws/src/chapter6_tutorials

even though the command catkin_make is being compiled in my root directory and no error occurs. To resolve this problem I have already gone through all the solutions provided online such as this, this and this. Tried everything such as

cd ~/catkin_ws
source devel/setup.bash

echo $ROS_PACKAGE_PATH
/home/khan/catkin_ws/src:/opt/ros/jade/share:/opt/ros/jade/stacks

$ rospack profile

roscd chapater6_tutorials
rosrun chapter6_tutorials pcl_create

and that's what I get

[rosrun] Couldn't find executable named pcl_create below /home/khan/catkin_ws/src/chapter6_tutorials

I have also tried running it from the root directory such

cd ~/catkin_ws
rosrun chapter6_tutorials pcl_create

still got the same answer.

My "chapter6_tutorials" package address is home/catkin_ws/src/chatper6_tutorials. In my" chapter6_tutorials", I have two files CMakeLists.txt and package.xml and only one folder naming "src" in which I have two files "pcl_sample" and "pcl_create" both of these files are created as per instructions given in the book. In my CMakesLists.txt I have already added following instructions

find_package(PCL REQUIRED)

## Add include directories
include_directories(include
      ${PCL_INCLUDE_DIRS}
)

## Add link directories
link_directories(
  ${PCL_LIBRARY_DIRS}
)

add_executable(pcl_sample src/pcl_sample.cpp)
add_executable(pcl_create src/pcl_create.cpp)

target_link_libraries(pcl_sample ${catkin_LIBRARIES} ${PCL_LIBRARIES})
target_link_libraries(pcl_create ${catkin_LIBRARIES} ${PCL_LIBRARIES})

It is also worth mentioning that I am using ubuntu15.04 with jade version of ROS.

I have already learnt how to create package from the tutorial (this) and I have also gone through how to make nodes following book and tutorials (a and b). Please, help if you can. I have spent a lot of time in it and stuck. Please, help, I shall bring cookies for you. :D :D :D
