Qt Creator rebuilds all headers and cpp files to new objects

When I add button to mainwindow form and paste some code inside derived function '
void MainWindow::on_pushButton_3_clicked()' , it takes 20 seconds to rebuild whole projectQuestion:
I can understand why does it rebuild moc_files, but why other objects?.
It rebuilds all headers and cpp files to new objects - why is that?What I'm trying to achive: I need deduct building time
Previously I had 20-30 sec, now It takes 3-9 seconds if affect cpp files, not including new headers and not changing previous derivationIf link some headers to shared lib it takes 10-20 seconds to compile and build, but it looks reasonable (it rebuilds all headers and cpp files to fresh objects)
I moved all Qt related headers to shared library (.so) and now it seems to build significantly faster

@JacobNovitsky hi,
You should double check your includes.
It seems you are having quite a lot of them. A good rule: include only what you actually use and use forward declarations for everything else. That should already drive down the compilation time. When using Qt, do not use module includes.

You asked the very same question in this post. As usual, you got a polite answer. As usual, you did not reply. So we don't know if it was helpful or not.
Thanks for calling my answer stupid and not helpful. Made my evening.
