Using OpenCV with Qt - c++

Question

I have been trying to use OpenCV with Qt Creator, but I had no success. I read lot of forums but none helped.
Here is my code:
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <qDebug>
#include <QCoreApplication>
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
cv::Mat image = cv::imread("lol.jpg");
cv::namedWindow("MyImage",45);
cv::imshow("MyImage",image);
qDebug()<<"TEST-OCV-1";
cv::waitKey(1000);
return a.exec();
}
My .pro File
QT += core
QT -= gui
TARGET = ocv1
CONFIG += console
CONFIG -= app_bundle
TEMPLATE = app
SOURCES += main.cpp
INCLUDEPATH += F:/OpenCV/opencv/build/include
LIBS += -LF:/OpenCV/opencv/build/x64/vc12/bin \
-llibopencv_core240d \
-llibopencv_highgui240d \
-llibopencv_imgproc240d \
-llibopencv_features2d240d \
-llibopencv_calib3d240d \
I have also tried including the libs like
LIBS += -LF:/OpenCV/opencv/build/x64/vc12/lib \
-lopencv_core249 \
-lopencv_highgui249 \
-lopencv_imgproc249 \
-lopencv_features2d249 \
-lopencv_calib3d249 \
And
LIBS += -LF:/OpenCV/opencv/build/x64/vc12/lib \
-lopencv_core249 \
-lopencv_highgui249 \
-lopencv_imgproc249 \
-lopencv_features2d249 \
-lopencv_calib3d249 \
But I keep getting this error, though a command prompt starts it just as the text press enter to exit.
