在configure 文件中可以得到的是 检测的是opencv4 但是 按照安装文档的话，我们安装的是3.3.目前正在尝试更新到opencv4.1.1;

@Savvy1995 @Woodenwang , what does this command do with you ?

pkg-config --libs opencv4

Try this before :

export PKG_CONFIG=/usr/bin/pkg-config && export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib64/pkgconfig/ && export LD_LIBRARY_PATH="/usr/local/lib64/"

And if it's not working, try to compile opencv with this params :

-D OPENCV_GENERATE_PKGCONFIG=ON
-D OPENCV_PC_FILE_NAME=opencv4.pc
