cmake3.10 mingw530编译opencv2.4.13.3

1.所需工具

qt-opensource-windows-x86-5.9.1.exe

opencv-2.4.13.3-vc14.exe

cmake-3.10.0-rc1-win32-x86.msi

2.安装

注意：

将Qt安装路径C:\Qt\Qt5.9.1\Tools\mingw530_32\bin添加到系统环境变量

cmake建议选择32位

3.编译

source code要选择到有CMakeLists.txt的文件夹下

• 选择对应的Compilers：

C:/Qt/Qt5.9.1/Tools/mingw530_32/bin/gcc.exe
C:/Qt/Qt5.9.1/Tools/mingw530_32/bin/g++.exe

• 勾选WITH_OPENGL和WITH_QT
  

• 点击Configure

• Generate
  

• cmd切换到"Whrer to build binaries"选定的位置，
• 输入mingw32-make

开始编译，时间比较长.....

结束后输入命令

• mingw32-make install

• 将源文件下的include文件夹和编译后的bin和lib文件夹拷贝出来，这些就是我们所需要的。
  

4.测试

• 将opencv对应的bin文件夹路径添加到系统环境变量

• 新建空的Qt工程，修改pro文件

QT       += core guigreaterThan(QT_MAJOR_VERSION, 4): QT += widgetsSOURCES += \    mian.cppINCLUDEPATH+=E:/mingw32-opencv2413/include/opencv2\              E:/mingw32-opencv2413/include/opencv \               E:/mingw32-opencv2413/includeLIBS += -L E:/mingw32-opencv2413/lib/libopencv_*.a

• 添加main.cpp文件
  

#include <QApplication>#include"opencv2/opencv.hpp"int main(int argc, char *argv[]){    QApplication a(argc, argv);    cv::Mat img=cv::imread("F:/img.jpg");    cv::imshow("test",img);    cv::waitKey();    return a.exec();}

5.安装过程中出现的一些问题

• CMake Warning at cmake/OpenCVPackaging.cmake:23 (message): CPACK_PACKAGE_VERSION does not match version provided by version.hpp header! Call Stack (most recent call first): CMakeLists.txt:1106 (include)

解决方法：

注释掉：# set(OPENCV_VCSVERSION "unknown")， 修改为openCV对应的版本：set(OPENCV_VCSVERSION "2.4.13")

• 解决CMP0020，CMP0071警告

Policy CMP0071 is not set
Policy CMP0020 is not set

解决方法：

• modules/highgui/CMakeFiles/pch_Generate_opencv_highgui.dir/build.make:62: recipe for target 'modules/highgui/precomp.hpp.gch/opencv_highgui_RELEASE.gch' failed

 解决方法：cmake -DENABLE_PRECOMPILED_HEADERS=OFF ...

• 如果报gpu相关的错误

解决方法：Try to add-D WITH_CUDA=OFF to yourcmake command line
