在centos7上安装Opencv的时候，停在了下载ippicv的地方，一直都下载不下来。ippicv是一个并行计算库，其实可以不用的。如果不想用这个并行计算库，在做Cmake的时候用参数关闭即可，但我还是建议使用这个库。首先，手动下载[ippicv](https://raw.githubusercontent.com/Itseez/opencv_3rdparty/81a676001ca8075ada498583e4166079e5744668/ippicv/ippicv_linux_20151201.tgz)然后，将刚才下载的ippicv文件直接拷贝进入opencv3.1源码的下面这个目录：
opencv-3.1.0/3rdparty/ippicv/downloads/linux-808b791a6eac9ed78d32a7666804320e

最后一个目录可能不一样，但无所谓。 最后再使用命令编译：

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
