win10 + Qt5.14.0（mingw73_64） 下的 OpenCV4.5.1源码编译 注意事项_missing:python_executable interpreter

大体的流程 别的博客上有，大体比较类似。这里不进行详细的介绍。

CMake 的版本 不能过高，例如3.19.x   之类的，我这里用的是3.10.x，否则会莫名其妙的失败。（用了最新的CMake导致的编译失败 就浪费了我一天的时间，还真的什么都不能用最新的）

勾选 WITH_QT
勾选 WITH_OPENGL
不勾选 OPENCV_ENABLE_ALLOCATOR_STATS  BUILD_opencv_world
CMAKE_BUILD_TYPE 选择 Release或Debug

勾选OPENCV_ENABLE_NON_FREE选项。【专利算法模块，包含特征检测和GPU相关的内容】

手动   添加环境     OPENCV_VS_VERSIONINFO_SKIP    bool     打勾

CMAKE_MAKE_PROGRAM    D:/Qt/Qt5.14.0/Tools/mingw730_64/bin/mingw32-make.exe

如果 安装了  Anaconda3  ，CMake configure的时候 会搜索到  python 之类的环境 ,然后会自动帮你  配置好，但是  我不想要python  啊。

解决方法： 先   删除Anaconda3  放入回收站 ，安装完 后再恢复。  搜索 python  把  有关的python 的  选项  都  不 选。

若使用opencv_contrib模块，记得 不勾选   BUILD_opencv_xfeatures2d   （这个会从国外下载一堆的模块之类的，但 国内防火墙....大家懂的）

OPENCV_EXTRA_MODULES_PATH:  若使用opencv_contrib模块，则在此处填写解压后的路径，如 D:\opencv_contrib\modules\
