[Libguestfs] Help

Dear sir, I am a newbie in coding. I am using ubuntu 14.04 in my machine and installed libguestfs by the following command: sudo apt-get install libguestfs-tools I get to run guestfish properly from terminal. But as it happens I want to write a program in C++ and i want to include the guestfs.h file in the program. I have tried and searched many options but have not found any. Is there something I am doing wrong? Can you please help me getting the file. If you can show me a way then it would be great cause I have been trying for three days in a row. Thanks Hasib
