Package opencv was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv' found
In file included from cppdbprocess.cpp:15:
include/postprocess_op.h:17:10: fatal error: opencv2/core.hpp: No such file or directory
 #include "opencv2/core.hpp"

在编译一个工程文件的时候,工程依赖OpenCV3以上,拉取了一个OpenCV4 docker镜像,编译的时候报上面的错误。

在/usr/local/lib/pkgconfig下面没有opencv.pc,但是有opencv4.pc,解决的方式就是建立一个opencv4.pc的软连接,命名为opencv.pc
