The serialnmea Qt5 positioning module is missing in the qt5-qtlocation package.
The problem is, the qmake .pro file for the plugins uses:
qtHaveModule(serialport):SUBDIRS += serialnmea
to enable the module which causes the module gets never build when the Qt location module is build separately on a system where the Qt serial port module is not installed.
This bug appears to have been reported against 'rawhide' during the Fedora 36 development cycle.
Changing version to 36.
