Not sure I understand what we're missing here. Is this a configuration that should be added to the package?

Turns out the f34 kate package was not built with KUserFeedback support,
inspecting logs from:
https://koji.fedoraproject.org/koji/buildinfo?buildID=1702053
CMake Warning at kate/CMakeLists.txt:50 (find_package):
By not providing "FindKUserFeedback.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"KUserFeedback", but CMake did not find one.
Could not find a package configuration file provided by "KUserFeedback"
with any of the following names:
KUserFeedbackConfig.cmake
kuserfeedback-config.cmake
Add the installation prefix of "KUserFeedback" to CMAKE_PREFIX_PATH or set
"KUserFeedback_DIR" to a directory containing one of the above files. If
"KUserFeedback" provides a separate development package or SDK, be sure it
has been installed.

Support was added later,
https://src.fedoraproject.org/rpms/kate/c/1b18efea96d61a569f2acf084e7240d3db4e05c1?branch=rawhide

We'll be bringing newer kate to f34 soon, I'll consider this closed
