c++链接redis（vs2015），链接redisvs2015

c++链接redis（vs2015），链接redisvs2015

（注：整个demo是在release模式下的）
1.链接redis之前，先解压github下载的整个zip。
redis-3.0->msvs->RedisServer
编译hiredis和Win32_Interlop,产生这两个.lib文件
（可能产生的错误：平台工具集不兼容，解决：
Project->Properties->General->Platform Toolset->vs2015 (v140)
高版本可以兼容低版本，低版本不能兼容高的。
）
（因为后面产生了报错，是关于运行时库mt和md的，根据实际需要去调整，又重新在release模式下编译生成lib）
2.头文件需要包含Win32_Interlop和hiredis全部的头文件。
hiredis的头文件在deps里，其中fmarcos.h要用src里的fmarcos.h替换
3.调整包含头文件和lib文件的目录方法同链接mysql，记得要加上hiredis和Win32_Interlop两个lib。
4.platform也要改成x64。
5.Project->Properties->C/C++->preprocessor defination：NO_QFORKIMPL，WIN32_IOCP
6.Project->Properties->C/C++->Code Generation->Runtime Library->MTD
7.把所有的头文件添加到工程中，因为有一个头文件，好像是win32那边的，会报错，因为路径问题。把他原来指定的相对路径换成现在目录下的路径就可以消除报错。
