opencv 3.3.1 contrib链接库名称：
最近使用opencv 3.3.1，想使用其中的sift等算子，结果按照教程调用之时才发现官方网站上直接下载的安装包并不包含。在网上找了半天之后才发现，由于sift算子已被注册专利，而且还有一些测试和稳定性因素，这些都被放在opencv_contrib里，放在opencv github之上，网址为：存放opencv_contrib的GitHub
我是用的是opencv 3.3.1，因此在GitHub release文件中下载的3.3.1版本，推荐使用与opencv版本相同的contrib文件。
安装的话
直接下载之后，得到的是zip文件，之后还需要进行配置。配置过程网上已经有了非常多的教程，在这里，我主要参考的是一下博客
博客1（写的很详细了）
博客2
利用CMake得到最后的install文件之后，在VS之中配置好调用路径就可以了。配置的方法与配置opencv相似，只是相较于opencv链接库，contrib文件的链接库多到可怕，在网上转了一圈也没发现opencv 3.3.1 contrib的各个链接库名字，就把自己install编译出来的链接库名字存储下来，方便之后的重新配置。
