本文解决使用CMake编译OpenCV及其贡献模块时遇到的错误：This algorithm is patented and is excluded in this configuration。通过设置CMake选项OPENCV_ENABLE_NONFREE为ON并重新构建库来解决问题。

使用cmake编译opencv（包含了opencv_contrib），执行cmake命令时报错：

error: (-213:The function/feature is not implemented) This algorithm is patented and is excluded in this configuration; Set OPENCV_ENABLE_NONFREE CMake option and rebuild the library in function 'create'".

解决方法在：

https://answers.opencv.org/question/201938/how-can-i-set-opencv_enable_nonfree-cmake-option-and-rebuild-the-library-in-function-create/

cmake -DOPENCV_ENABLE_NONFREE:BOOL=ON -D CMAKE_INSTALL_PREFIX=/usr/local -D CMAKE_BUILD_TYPE=Release -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules ..

（参数中路径要根据自己的机器更改一下啦）
