CMake Error: CMake was unable to find a build program corresponding to “MinGW Makefiles“.解决方案（亲测有效）

CMake编译OpenCV4.6.0过程中一直出错：

CMake Error: CMake was unable to find a build program corresponding to “MinGW Makefiles”. CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.

解决方案如下：

将CMAKE_MAKE_PROGRAM项后面的路径设置为Qt安装路径下的路径。例如：D:/Qt/Qt5.12.12/Tools/mingw730_64/bin/mingw32-make.exe （该路径根据你QT的按照路径来定）。

重新点击Configure，问题解决！
