cpu_bitmap.h header file problem!!!

I am learning cuda c programming using examples from the text “cuda by example”. In the fourth chapter, there is a demonstration to draw julia set which uses a header file “cpu_bitmap.h”. I could not find this header file in my system and hence I am stuck with the program. Can anyone tell me from where I can download the header file and how to install it

It is in “common” directory in the example source codes to the book, see https://developer.nvidia.com/content/cuda-example-introduction-general-purpose-gpu-programming-0

Thank you hadschi118. thank you very much…
