问题：
/usr/bin/ld: cannot find -lippicv
collect2: error: ld returned 1 exit status
解决方案一、
解决方法：找到-lippicv对应的库（libippicv.a），该库位于 安装目录opencv-3.1.0/3rdparty/ippicv/unpack/ippicv_lnx/lib/intel64文件夹下 ，进入该文件夹下执行
sudo cp libippicv.a /usr/local/lib/即可
sudo cp libippicv.a /usr/local/lib/
继续执行make 即可
解决方案二、
找到ippicv
执行：
locate ippicv
输出所有ippicv存在的路径：
