What does $$[QT_HOST_DATA/get] do?

Diracsbracket

Hi.
Where is the following syntax used in a feature configuration (.prf) file? defined:

$$[QT_HOST_DATA/get]

I know $$[ ... ] is to access QMake properties as explained in the Qt doc, but where is the /get part of the notation in $$[QT_HOST_DATA/get] clarified? And what does it precisely do?

Also, inside a Qt .conf file, what is the difference between include (for other .conf files) and load() (for .prf files)?
If include(some.conf) merely consists in the contents of some.conf to be literally pasted into the including .conf file, what does the load() do exactly?

I have found no info about the structure of .prf files.
https://doc.qt.io/qt-5/qmake-advanced-usage.html says that you can create .prf files, but says nothing about how these files are processed or should be structured?

Thanks for any clarifications you can provide!

Hi,

The structure is the same as .pro file. The language doesn't change, just the functionality it represents.

Yes I read that, but it does not explain what the /get does in $$[QT_HOST_DATA/get] or why it is needed.

I asked the question on StackOverflow and had some better luck there:

Cheers, and thanks for reacting!
