Windows安装包种类：
1、MSI 一般用于驱动程序，安装时直接覆盖已有文件和程序
2、EXE 常用的安装程序，缺点是卸载时会有残留文件
3、APPX uwp应用推出时推出的一种安装包，只能用于windows8之后，之前的应用打包为此种格式比较复杂，不流行
4、MSIX 最新推出的格式支持windows所有平台(桌面、手机、平板)，类似于苹果的安装包，需要签名，安全，做到干净卸载。windows 10后推出，且微软也提供了工具将上面四种安装包转换为MSIX格式安装包
虽然MSIX是windows推荐的安装包，也具有安全，无残留的有点，不过对于桌面端程序目前还是exe占主流。
Windows下exe安装包打包流程
- Power Shell环境配置
执行如下命令更改Power Shell执行策略(否则无法运行脚本)
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

Windows的可执行文件引用的三方动态库(dll)描述只有相对路径一种方式(相对于可执行文件的路径)，所以拷贝三方库后也就不需要MacOS中的步骤（4）了，而且exe安装包也不需要签名，Qt官方也给出了步骤（3）的工具windeployqt
构建脚本
将 install_win.iss 文件与脚本放置于同一个目录下，install_win.iss内容如下：
; Script generated by the Inno Setup Script Wizard.
; SEE THE DOCUMENTATION FOR DETAILS ON CREATING INNO SETUP SCRIPT FILES!
#define MyAppName "MytestApp"
#define MyAppVersion "1.5"
#define MyAppPublisher "My Company, Inc."
#define MyAppURL "https://www.example.com/"
#define MyAppExeName "MytestApp.exe"
