i tried to delete the file and the folder and i get:

It looks like Qt is not considering an already-existing directory may spoil things. Can you please provide the full sequence of commands you used to get to this state? I suspect Qt should pass --fresh if CMake is 3.24 or newer and make noise otherwise if CMakeFiles/ or CMakeCache.txt already exist in the build directory of interest.

Qt’s configure allows reconfiguring in an existing build directory, so removing CMakeCache.txt and friends or complaining about it is not possible, because the intent might be to do a reconfiguration with slightly different options, rather than a clean configuration from scratch.

Qt’s configure accepts --fresh, so if the intent is to do a clean build, that can be explicitly passed.

I’m not sure how the OP ended up in their situation.
It also looks weird that they call cmake on the top-level source dir “Src” within a qtbase subdirectory.
Either they should call configure from “Src/qtbase/configure”, or call “Src/configure” but not within a qtbase build subdirectory.

cmake --fresh . let the configuration finish!

but then cmake --build . gives me: stuv@localhost:~/Qt/6.6.0/Src$ cmake --build .[ 1%] Generating pc file for ta - Pastebin.com

You’re trying to build Qt WebEngine and it fails due to a missing cups-config binary. You will either need to skip building WebEngine, or install all required dependencies.

Having said that, the CMake forum is not the right place to seek support for building Qt.
A more appropriate place would be the Qt forums at https://forum.qt.io/
