解压后，直接cmake ，我这种弱鸡直接用cmake gui了

直接编译不会报错，（C++圈里的库已经越来越人性化，不像往年编译个库报错一堆各种坑）

注意：如果你需要静态库，这里不要勾选

生成lib直接使用

因为是静态库了 他源码是依赖socketlib的，所以要在你的项目里也加上这句
#pragma comment(lib,"ws2_32.lib")

以下是测试代码：

// redis_test.cpp : 此文件包含 "main" 函数。程序执行将在此处开始并结束。
//

#include <iostream>
#include "hiredis.h"
#include <string>
#pragma comment(lib,"hiredisd.lib")
#pragma  comment(lib,"ws2_32.lib")
using namespace  std;

    if (reply && reply->type == REDIS_REPLY_INTEGER && reply->integer > 0) {
        freeReplyObject(reply);
        return true;
    }
    freeReplyObject(reply);
    return false;

    redisContext *conn = redisConnect("127.0.0.1", 6379);
