This application failed to start because no Qt platform plugin could be init...
If "xcb" things missing, we should "dnf install libxcb..." like above, and an annoying step we can't image is after we install required packages, we must delete CMakeCache.txt first and then to invoke cmake, if not, some modules like xcb-sm are always displayed not to be built.
Feature accessibility_atspi_bridge is already defined to be "OFF" and should now be set to "ON" when importing features from Qt6::Gui.
We only need to not let the message interrupt building progress,
/mnt/SDC2/qt/bld/installed/lib/cmake/Qt6/QtFeature.cmake:1136
message(STATUS "Feature ${feature} is already defined to be \"${QT_FEATURE_${feature}}\" and should now be set to \"${value}\" when importing features from ${target}.")
