先去在/usr/local/lib目录下查看，找到了libopencv_core.so.3.3
再接着执行：
ubuntu@ubuntu-ST-KN:~/caffe$ cat /etc/ld.so.conf
include /etc/ld.so.conf.d/*.conf
ubuntu@ubuntu-ST-KN:~/caffe$ sudo echo "/usr/local/lib" >> sudo /etc/ld.so.conf
ubuntu@ubuntu-ST-KN:~/caffe$ sudo ldconfig
ubuntu@ubuntu-ST-KN:~/caffe$ sudo make runtest -j8
