Your are trying to use KF5 KArchive in a Qt6 application.

You can't do that, KF5 needs Qt5.

You can try using the KF6 beta release of KArchive or wait until we release 
KF6 at the end of the month.

This is not a KDE question, this is a "I understand how compiling things with 
cmake works" question.

The usual answer is that you run cmake && ninja && ninja install (replace 
ninja by make or if you really don't have any of those by cmake commands that 
will build and install) in karchive and then point the cmake of your 
application to that folder you installed karchive, either via a command line 
option or by hardcoding the path in the CMakeLists.txt file.

But Windows developers don't like that so you may have luck doing a cmake 
submodule thing, but then you're on your own, that's generally not how we use 
libraries.
