Bonsoir ,

J'ai déja terminer mon application en utilisant QT Creator et la bibliothèque OpenCV sur le système linux .

Mais maintenant j'essayer d’intégrer mon application sur windows 7 64bits de même avec QT Creator . et j'ai rencontrer des probéleme de linker avec la bibliothèque OpenCV .
voila mon .pro
