Brew is failing to install kf5-kxmlgui

SUMMARY I'm trying to install Heaptrack through Brew in my MacOS so I can use heaptrack_gui and when I follow the steps in the guide (https://github.com/KDE/heaptrack#compile-heaptrack_gui-on-macos-using-homebrew) it gets to a part where it attempts to install kde-mac/kde/kf5-kxmlgui and cmake/ninja are throwing the following error:

STEPS TO REPRODUCE

1. On MacOS, ensure you have Homebrew installed
2. Run: brew tap kde-mac/kde https://invent.kde.org/packaging/homebrew-kde.git
3. Run: "$(brew --repo kde-mac/kde)/tools/do-caveats.sh"
4. Ensure that here are no errors
5. Run brew install kf5-kxmlgui
6. Observe the error described above

OBSERVED RESULT Ninja/cmake are failing to build kf5-kxmlgui

EXPECTED RESULT Brew should install kf5-kxmlgui correctly
