The Qt Installer Framework Manual Component Scripting section mentions Predefined Variables and there I also read

If embedded in '@' they can also be part of strings passed as arguments to installation operations

These variables are evaluated at runtime, the time when the installer is running.

I'm wondering if I can pass a variable in, to evaluate at build time? The time when the installer is being build.

If you ask me why? I would like to set the name of the icon installed on the desktop. At the time I call binarycreator not having to open/edit the installscript.qs.
