【问题解决】 Could not find a package configuration file provided by “OpenCV“ with any of the following n

【问题详述】

编译依赖于opencv的包时报错

Could not find a package configuration file provided by “OpenCV” with any of the following names:
OpenCVConfig.cmake
opencv-config.cmake

【解决办法】

这个问题是找不到 “OpenCVConfig.cmake” 或 “opencv-config.cmake” 文件，主要是找不到 OpenCV 路径而导致的。

造成这个问题的主要原因就是没有安装opencv，或者重装了opencv

所以要先确定opencv的路径，这个路径是包含 OpenCVConfig.cmake 文件的目录
确保这个路径包含 OpenCVConfig.cmake 文件

然后打开编译不通过功能包的CMakeLists.txt文件
找到下面的语句

#set(OpenCV_DIR "/usr/share/OpenCV/")
#改为
set(OpenCV_DIR "/home/victor/opencv-4.2.0/build/")
1

再次编译即可
