配置 source code 和 build the binaries

点击Configure

工程类型配置

工程类型选则： MinGw Makeifile

编译器选择：QtTools 下的 MinGw/bin gcc and g++

等待配置完成显示 Configuring done

配置安装路径

CMAKE_INSTALL_PREFIX  E:/opencv/MinGw_64

配置modules

OPENCV_EXTRA_MODULES_PATH  E:/opencv/opencv_contrib-4.4.0/modules

在CMakeGui Search栏搜索 CMAKE_INSTALL_PREFIX 和 OPENCV_EXTRA_MODULES_PATH，即可找到对应的配置项。

配置支持Qt

WITH_QT	TRUE

在CMakeGui Search栏搜索 WITH_QT 即可找到对应的配置项。

配置OPENGL

WITH_OPENGL TRUE

取消Test编译

BUILD_PERE_TESTS FALSE
BUILD_TESTS FALSE
BUILD_opencv_python_tests FLASE

OPENCV_ENABLE_ALLOCATOR_STATS FALSE
OPENCV_GENERATE_SETUPVARS FALSE

在CMakeGui Search栏搜索 test 即可找到对应的配置项,全部取消

配置完成后继续点击Configure

QT5_DIR配置

在点击Configure 之后会有如下错误提示：

CMake Error at cmake/OpenCVFindLibsGUI.cmake:18 (find_package):
  Could not find a package configuration file provided by "Qt5" with any of
  the following names:
Qt5Config.cmake
    qt5-config.cmake
    Qt5Config.cmake
    
  Add the installation prefix of "Qt5" to COPENCV_ENABLE_ALLOCATOR_STATSMAKE_PREFIX_PATH or set "Qt5_DIR"
  to a directory containing one of the above files.  If "Qt5" provides a
  separate development package or SDK, be sure it has been installed.
Call Stack (most recent call first):
  CMakeLists.txt:686 (include)
Configuring incomplete, errors occurred!

该错误是没有找到Qt5 的安装路径。

在Everything 搜索 Qt5Config.cmake，即可找到对应路径。

在如上目录查看是都有对应的文件，没有则打开

E:\opencv\MinGw_64_build\CMakeDownloadLog.txt

找到下载路径，下载对应的文件。

编译

管理员权限打开 powershell ,执行如下命令：

PS E:\opencv\MinGw_64_build> E:\Qt\Qt5.12.2\Tools\mingw730_64\bin\mingw32-make.exe -j8

E:\Qt\Qt5.12.2\Tools\mingw730_64\bin\mingw32-make.exe -j8

mingw32-make.exe 路径为对应 Qt mingw 安装路径。

libdir / includepath 配置

在Pro文件内部添加：

INCLUDEPATH += E:\opencv\MinGw_64\include\
INCLUDEPATH += E:\opencv\MinGw_64\include\opencv2\

win32:CONFIG(release, debug|release): LIBS += E:/opencv/MinGw_64/x64/mingw/lib/libopencv_*.a

因为只编译了 release 版本，所以只添加了Release
