how to install Okular viewer on macOS Big Sur, using M1/Apple Silicon/arm64

okular-appleSilicon.md

1. Install homebrew from https://brew.sh/ (follow the instructions there)
2. tap the https://invent.kde.org/packaging/homebrew-kde/ repo, brew tap kde-mac/kde https://invent.kde.org/packaging/homebrew-kde.git
3. brew edit okular, workaround now is to comment out or delete the line depends_on "chmlib" (won't compile on macos arm64 for now as of 2021-08-18), then save (if using vim you need to first press i to insert/type, when saving then <esc> then :wq then <enter>.
4. brew install okular, wait for stuff to compile and/or install
5. It may ask for keychain credentials (to sign the binaries? because of mac arm64 security policy https://eclecticlight.co/2021/01/26/when-you-dont-have-permission-to-run-an-app-on-an-m1-mac/)
6. $(brew --repo kde-mac/kde)/tools/do-caveats.sh
7. Now okular is in your $HOME/Applications/KDE folder, and will show up in Launchpad! You can view pdf, djvu, etc documents.

not working for me either.
I did many things to try and work this through. KF5I18n package seems to not be found when trying to install Okular... Like KF5I18n uses KF5, but the KF5I18n package in homebrew actually installs KF6I18n, which is Version 6.0.0 and I have a feeling that makes it harder to find when looking for the dependency while building with homebrew.

Could not find a package configuration file provided by "KF5I18n"
(requested version 5.111.0) with any of the following names:

KF5I18nConfig.cmake
kf5i18n-config.cmake

Add the installation prefix of "KF5I18n" to CMAKE_PREFIX_PATH or set
"KF5I18n_DIR" to a directory containing one of the above files. If
"KF5I18n" provides a separate development package or SDK, be sure it has
been installed.

Could not find a package configuration file provided by "KF5I18n" (requested version 5.111.0) with any of the following names:

I'm getting this exact same error, including:

Warning: Unable to query GitHub for recent issues on the tap
Validation Failed: [{"message"=>"The listed users and repositories cannot be searched either because the resources do not exist or you do not have permission to view them.", "resource"=>"Search", "field"=>"q", "code"=>"invalid"}]

I have the same error with "KF5I18n". Unable to install at this time.

Exactly the same error:

-- Configuring incomplete, errors occurred!

Im having the same issue with KF5I18n, did anyone manage to figure that out?

thanks!
