Qmake TEMPLATE variable manipulation via command line interface

[Patrick Fromberg]

According to the documentation this variable can have value lib or app or subdirs or etc...
Why is TEMPLATE += or TEMPLATE-= not a syntax error then? Those are operators on list variables.

The documentation of the cli option -t explains that it overwrites the TEMPLATE variable after processing the pro file. What effect can any variable change have after processing is complete? "After proessing" sounds to me a little bit like "when it is to late"

The documentation of the cli option -tp explains that this will add a prefix to the TEMPLATE variable. The documentation of the TEMPLATE variable does not say anything about a prefix. What would prefix.lib as TEMPLATE value mean? Just like the other option, will this be "after processing"?

Ah and one additional question. Will qmake command line options applied to a subdirs project also recurse to the child projects?

Most probably because nobody bothered to make it into an error.

After parsing sounds better? I guess that is what they have meant.

This is used on Windows to generate Visual Studio stuff, I think. More info https://stackoverflow.com/questions/1043294/qt-qmake-tp-vc-to-create-visual-studio-project-files

Yes, as far as I remember. Just try it out ;-)
