前言
Qt使用一些压缩解压功能，选择libzip库，libzip库比较原始，也是很多其他库的基础支撑库。
libzip
libzip是一个C库，用于读取，创建和修改zip档案。可以从数据缓冲区，文件或直接从其他zip归档文件直接复制的压缩数据中添加文件。在不关闭存档的情况下所做的更改可以还原。
当前版本是1.7.3，于2020年7月15日发布。

libzip编译
步骤一：解压
步骤二：Cmake配置（vs2017 x64版本）
需要zlib，之前已经编译过vs2017 x64版本的zlib了，导入再配置
步骤三：生成工程
步骤四：打开VS2017编译
步骤五：安装install
模块化
补充：查看命令行工具帮助和源码辅助开发
