how to convert .ui fully into c++ header and source file - c++

Question

I created something with the Qt Creator Design-Tool.
By doing so I endet up with a .ui, a .h and two .cpp (mainwindow.cpp and main.cpp) files containing the following:
mainwindow.ui:

Now I what I'd like to have is a .cpp file containing not only the signals and slot I created manually, but everything. Every layout I added with the designer, every label, every button. And as far as I know there is a way to achieve exactly that: qmakeor uic
The problem now is: how do I actually use one of those?
I've tried using uic via command prompt by opening the folder all those files are in and executing this: uic -o mainwindow.h mainwindow.ui
(googled a bit and found that)
But the error I got was something like this: either the "uic" command written wrongly or couldn't be found. (tried to translate it from my language)
Any ideas on how to fix the problem or any different ideas on how to achieve what I need?

Answer 1

Use qmake, here's the link with all basic explanations:
https://doc.qt.io/qt-5/qmake-tutorial.html
For .ui files, you add them to the .pro file like this:
FORMS += foo.ui
