QT工程配置OpenCV3

1. 新建QT Plain C++ Application工程
   
2. 新建的工程目录如下
   
3. 将.pro文件内容修改如下

TEMPLATE = app
CONFIG += console c++11
CONFIG -= app_bundle
CONFIG -= qt

SOURCES += \
        main.cpp
INCLUDEPATH += /usr/local/include
LIBS += -L/usr/local/lib\
        -lopencv_core \
        -lopencv_imgproc \
        -lopencv_highgui \
        -lopencv_ml \
        -lopencv_video \
        -lopencv_features2d \
        -lopencv_calib3d \
        -lopencv_objdetect \
        -lopencv_contrib \
        -lopencv_legacy \
        -lopencv_flann

4. main.cpp文件内容为

#include <iostream>
#include<opencv2/opencv.hpp>
using namespace cv;
using namespace std;
int main()
{
    Mat image(50,100,CV_8UC3,Scalar(200,0,0));
    cout << "Hello World!" << endl;
    imshow("win",image);
    waitKey(0);
    return 0;
}

5. 然后执行build run
