CMake编译OpenCV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安装路径下的路径如下所示：C:/Qt5.11.1/Tools/mingw530_32/bin/mingw32-make.exe，重新点击Configure，问题解决！
