Symbol(s) not found for architecture x86_64 in QtCreator unsing OpenCV

Question

I installed OpenCv via Macports and QT-Creator on my Mac. I included the header Files both to my Project

#include <opencv/cv.h>
#include <opencv/highgui.h>

Inside the .pro File and configured it like this

INCLUDEPATH += /opt/local/include/

LIBS += -L/opt/local/lib/

I am just using imgread to load an image. But if i compile i got an error like

symbol(s) not found for architecture x86_64

So it seems that my configuration is wrong in some way ? Does anybody know what i am doing wrong ? Or how do i import and install openCV inside QT under Mac OS 10.7.5 ?

I had success specifying the specific libs as shown here: http://stackoverflow.com/a/17552660/840992 — spring, Aug 15 '13 at 17:40

Right-click on the message

symbol(s) not found for architecture x86_64

and select Show Output (O).

You will then see the full message that QtCreator has been hiding.

Ok, after looking around in the Internet i found the following Solution :

INCLUDEPATH += /opt/local/include

LIBS += -L/opt/local/lib

LIBS += -lopencv_calib3d \
-lopencv_contrib \
-lopencv_core \
-lopencv_features2d \
-lopencv_flann \
-lopencv_gpu \
-lopencv_highgui \
-lopencv_imgproc \
-lopencv_legacy \
-lopencv_ml \
-lopencv_objdetect \
-lopencv_video
