I'm currently doing a project using QT creator, which including openGL and parallel processing-windows thread.
I'm a totally newbie to QT and now I'm learning how to link openGL to my project through tutorial that found on web.
I found that I couldn't link glut.h to my project and once I compile everytime, this error will occured.

D:\Academic\QT\test-build-desktop-Qt_4_7_4_for_Desktop_-_MinGW_4_4__Qt_SDK__Debug\..\test\main.cpp:3: error: GL/glut.h: No such file or directory
D:\Academic\QT\test-build-desktop-Qt_4_7_4_for_Desktop_-_MinGW_4_4__Qt_SDK__Debug\..\test\main.cpp:-1: In function 'int qMain(int, char**)':
D:\Academic\QT\test-build-desktop-Qt_4_7_4_for_Desktop_-_MinGW_4_4__Qt_SDK__Debug\..\test\main.cpp:7: error: 'glutInit' was not declared in this scope

How I manage to solve this?
Thanks in advance.
