With an install scripting tool like Nullsoft Installer, Inno Setup, Microsoft MSI files, ...

can u explain much more?

Qt doesn't provide a deployment packaging tool for Windows so you have to use a third party tool. I have listed a couple of the commonly used ones. How you use them is a matter for their manuals and tutorials. In short:

• Build and test your Qt project
• Work out what you need to deploy: Deploying Qt Applications
• Write a script for your installer generator of choice
• Run your installer generator of choice to build your installer.
• Profit
