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.

Exactly the same error:

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.

-- Configuring incomplete, errors occurred!

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

thanks!
