https://stackoverflow.com/questions/58478074/how-to-fix-fatal-error-opencv2-core-hpp-no-such-file-or-directory-for-opencv

直接包含core文件(opencv4/opencv2/core/core.hpp)会引起

fatal error: opencv2/core/cvdef.h: No such file or directory

参考解决方法

Cmakelists.txt中写入opencv路径

include_directories ("/usr/include/opencv4/")
