same to you bub :)
I'm not sure what you're referring to @JackBoosY

[JackBoosY]

@winterz I just restart the CI test.

@winterz
I also noticed that you have added these two ports qt5-kdreports and qt5-kdsoap in this PR.
Could you add them in a separate PR? Please refer to this doc.

As qt5-kdreports and qt5-kdsoap belong to qt5. You can refer to other qt5 components to add them.
So please remove these two ports from this PR.
