问题描述：

By not providing "FindOpenCV.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "OpenCV", but
CMake did not find one.

Could not find a package configuration file provided by "OpenCV" with any
of the following names:

OpenCVConfig.cmake
opencv-config.cmake

Add the installation prefix of "OpenCV" to CMAKE_PREFIX_PATH or set
"OpenCV_DIR" to a directory containing one of the above files. If "OpenCV"
provides a separate development package or SDK, be sure it has been
installed.

解决方案：

首先使用指令搜索OpenCVConfig.cmake文件的路径：

locate OpenCVConfig.cmake

然后，在CmakeLists.txt中添加：

set(OpenCV_DIR home/haha/opencv)

说明：home/haha/opencv 为OpenCVConfig.cmake所在路径
