Как сделать связку QT3 с SDL?, Программа должна быть написана QT->SDL Опции

[dell]

Программа должна быть написана на QT и местами должна использовать<SDL.h>

Как подключить библиотеки SDL к про файлу QT с последующей компиляцией в Linux (использую FC, ASPLinux)?
Как на виджете выводить графику (поверхности SDL)?

ЗЫ
Братцы помогите, кто чем может гуглю нечего не могу найти
Нужен пример ткните носом плиз.

извини, возможно это покажется не умный совет, но посмтори статью про qmake и ее подраздел про файлы проекта, там упоминается подключение сторонних библиотек

Пример связки Qt 4.0.1 и SDL 1.2.8-08:
main.pro

TEMPLATE = app
LANGUAGE = C++
TARGET = qtSDL
PROJECTNAME = SPARTA Video Tracking Demo
CONFIG += qt thread warn_on debug

INCLUDEPATH += /usr/include/SDL

LIBS += -lSDL

SOURCES    = SDLWidget.cpp main.cpp

HEADERS = SDLWidget.h
