Missing header when compiling in Qt Creator

[embdev]

Hi fellow coders, I encountered missing header when compiling my code.
i.e. the following header is missing:

linux/module.h: No such file or directory
#include <linux/module.h>

However, I can find this file in my vendor supplied Linux SDK, residing in /Home/. How may I 'tell' the source code to look for the headers in my vendor supplied Linux SDK instead?

@embdev See http://doc.qt.io/qt-4.8/qmake-variable-reference.html#includepath
Don't forget to rerun qmake after modifying pro file.
