cmake 中 Error in configuration process, project files may be invalid

qt配置opencv时，用到cmake，弹出窗口“Error in configuration process, project files may be invalid”错误，主窗口显示“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.”如下图：

上述错误源自没有找到正确的make工具，需要设置。

解决如下图：

将CMAKE_MAKE_PROGRAM的值改为qt的mingw32-make.exe，configure即可。
