1 查看linux下opencv安装库含路径
pkg-config opencv --libs
2 查看opencv安装版本
pkg-config opencv --modversion
3 查看opencv安装路径
sudo find / -iname “opencv”
4 在全盘上不区分大小写，搜索带有关键字opencv的所有文件及文件夹都会输出到终端，如果输出太长建议输出到txt文件里查看，如下：
sudo find / -iname “opencv” > /home/ubuntu/Desktop/opencv_find.txt
5 ubuntu16.04 head files and libs
head file address 头文件地址
/usr/include/opencv2/opencv.hpp
Lib address opencv库地址
/usr/lib/x86_64-linux-gnu
示例代码编译：
g++ main.cpp -o main -I /usr/local/include -L /usr/local/lib -lopencv_core -lopencv_highgui
