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.

Cheers,

If I may suggest joining the KDE Windows channel on Matrix. You can 
discuss there with KDE developers who are familiar with compiling KDE 
software on Windows. https://go.kde.org/matrix/#/#kde-windows:kde.org

What distro are you using?

In order to install a library in such a way that you can use it in 
new programs, you have to install both it and its development header 
files. There are generally two ways to do this:


* The easy way - install the development header package for your 
library of choice through your distro's package manager.
* The hard, dangerous way that you probably don't want yet - build 
the library from source and then either install it directly or figure 
out how to point your build system to it.


Obviously I'd recommend the former if you're just getting started. On 
Ubuntu, the package you want is called "libkf5archive-dev", and can 
be installed with "sudo apt install libkf5archive-dev". This will 
probably work on Debian too. If you're on some other distro, you'll 
need to find and install the right package.



I added the following to my project's "CMakeLists.txt" as described 
on the web page 
https://marketplace.qt.io/pages/karchiveinstructionspage 
 :


find_package(KF5Archive)
target_link_libraries(Example4 KF5::Archive)

Attached is my "CMakeLists.txt" file and "Main.cpp" file.

In my "Main.cpp" the syntax-checker indicates that it can't find 
"kzip.h" (probably because I don't know how to download/install it).
