The CPackIFW help page says about the variable `CPACK_IFW_TARGET_DIRECTORY`: "Default target directory for installation. By default used `@ApplicationsDir@/CPACK_PACKAGE_INSTALL_DIRECTORY`"
What kind of macro is this `@ApplicationsDir@`? Where is it defined, how does it expand by default, how can it be modified?

It seems to be an IFW pre-defined variable according to [this report](https://bugreports.qt.io/browse/QTIFW-514). I see documentation for it on [this IFW doc page](https://doc.qt.io/qtinstallerframework/scripting.html).
