Mac平台下QT＋Opencv 环境搭建

1. 下载安装Xcode
   可以直接从App Store下载。
2. 下载并安装QT creator
   地址：http://download.qt.io/official_releases/qtcreator/
3. 下载并安装QT开发包
   地址http://download.qt.io/official_releases/qt/
4. 配置QT
   
   
   注意在Qt版本那个地方可以通过QT开发包的的../Qt5.7.0/5.7/clang_64/bin/qmake获得。

5. 配置OpenCV
   在新建的QT工程中的.pro文件中添加如下配置代码

   INCLUDEPATH += /usr/local/include
   INCLUDEPATH += /usr/local/include/opencv
   INCLUDEPATH += /usr/local/include/opencv2
   LIBS += -L/usr/local/lib \
    -lopencv_core \
    -lopencv_highgui \
    -lopencv_imgproc \

   完成以上步骤后按理应该是能成功的，但是运行时发现会出现如下的错误。

   dyld: Symbol not found: __cg_jpeg_resync_to_restart
   Referenced from: /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO
   Expected in: /usr/local/lib/libjpeg.8.dylib
   in /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO

6. 针对以上问题还需要最后修改下配置，如下图
