/***************************************************************************************************
*
* Notes about how to configure your OpenCV environment and project.
* 1. You can prepare the required installation package from the official website. https://opencv.org/releases.html
* 2. If the *.lib files doesn't exist in the package download, you need to compile by yourself with the CMake tool.
* 3. Add the 'bin' folder path to the PATH.
* 4. Configure the 'Additional Include Directories', 'Additional Library Directories' and 'Additional Dependencies' for current project property.
*
* If there is any question or request, please feel free to contact us.
