Besides Kevin's code, you have two additional problems.
The sourceforge project shows that the project is GPL, but none of your source files contain any reference to the GPL and a copy of the GPL is not included with your source. The bottom of this page tells you how to properly apply the GPL
http://opensource.org/licenses/gpl-license.php
In addition, since you don't own the IFI code, you can't license it as GPL, so their code should be removed from your project as well.
