ubuntu16.04下配置Qt+OpenCV开发环境

上面先在ubuntu上安装了qt，由于我的工程里面要用到opencv，所以要配置qt+opencv的开发环境。

系统：Ubuntu16.04 64位
Qt：Qt5.7.0+Qt Creator4.0.2
OpenCV：opencv-3.2.0
（查看ubuntu下opencv版本：pkg-config --modversion opencv）

1.上一篇已经介绍了qt的详细安装过程，电脑里之前就已经安装了opencv了，所以下面只介绍qt+opencv的配置：
1.1首先用QtCreator新建一个Qt Console Application：New project->Application->Qt console Application,下面的一直点下一步就行。
1.2要将opencv的头文件和库文件与Qt关联起来，所以在双击QtCreator工程下到*.pro文件，在其后面添加下列代码，下面是整个.pro文件所包含的内容，我们要添加的只是INCLUDEPATH 和NCLUDEPATH部分。

#-------------------------------------------------## Project created by QtCreator 2017-07-21T10:33:43##-------------------------------------------------QT       += core guigreaterThan(QT_MAJOR_VERSION, 4): QT += widgetsTARGET = ttyUSB0_demoTEMPLATE = appSOURCES += main.cpp\        mainwindow.cpp \    gps_uart.cppHEADERS  += mainwindow.h \    gps_uart.hFORMS    += mainwindow.uiINCLUDEPATH += /usr/local/include \                /usr/local/include/opencv \                /usr/local/include/opencv2NCLUDEPATH += /usr/local/include/opencvLIBS += -lopencv_core \-lopencv_imgproc \-lopencv_highgui \-lopencv_ml \-lopencv_video \-lopencv_features2d \-lopencv_calib3d \-lopencv_objdetect \-lopencv_contrib \-lopencv_legacy \-lopencv_flann

这样就OK了
