As I've briefly introduced, this is a minimal, but complete and production-ready CMake project template for Qt 5 projects. This may be a starting point for your new application. If that is not intent to be a cross-platform project, you can clean up that stuffs from the template.

• Handling all possible Qt stuffs (UI, resources, translations)
• macOS bundle
• Windows executable icon

If you want to deploy your application on macOS, I would recommend you read below documents.

• Qt for macOS
  • Qt for macOS - Deployment
  • Qt for macOS - Specific Issues

If you want to deploy your application on Windows, I would recommend you read below documents.

• Qt for Winodws
  • Qt for Windows - Deployment
