qtConfig in qt 6,how it works?

[bigbigbig]

I just got "qthavemodule" in manual

so who can tell me ,how "qtConfig" works?

@bigbigbig qtHaveModule() and qtConfig() are defined in .../mkspecs/features/qt_functions.prf.

The first looks for the named module in only the QT variable (as documented).

The second is undocumented AFAICT, but looks for its argument in the list of Qt modules that are available in the QT variable and default private internal lists, considering dependencies and features enabled at Qt build time. This is likely only ever intended for internal use.

Your requires() condition is not naming a Qt module so will likely never be true.
