LinuxQuestions.org - [SOLVED] Where to find kf5* packages/files

Hello, folks. I'm in process of building a programs that works with qt5. However, I've faced an error

Code:

CMake Error at /usr/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:165 (message):

  Could NOT find KF5 (missing: CoreAddons I18n) (Required is at least version

  "5.44")

Call Stack (most recent call first):

  /usr/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:458 (_FPHSA_FAILURE_MESSAGE)

  /usr/share/ECM/find-modules/FindKF5.cmake:94 (find_package_handle_standard_args)

  CMakeLists.txt:51 (find_package)

I do have extra cmake modules from alienBOB repository, but I have no idea where to find this KF5* files. I've tried to find them with

Code:

find ~/Slackware/mirror/ktown/x86_64/ -iname '*.t?z' | while read -r PKG; do if [[ $(tar tf "$PKG" | grep -i kf5) ]]; then echo $PKG; fi; done

It brought me 164 packages that contain kf* in someway. What package do I need?
