Oh, I just looked at the macOS source build instructions for ROS 2 Humble: https://docs.ros.org/en/humble/Installation/Alternatives/macOS-Development-Setup.html#install-prerequisites. It install tinyxml from a custom formula: osrf/simulation/tinyxml1. I can try switching to that to keep Humble support.

Looks like osrf/simulation/tinyxml1 requires an old version of CMake and brew now installs CMake version 4.0.2, so the build fails.

Let's try to use an older version of the formula to install version 3.31.1 (https://stackoverflow.com/a/58148648), which is the version mentioned in REP 2000 for Kilted on macOS. It should work for this.

Ah, osrf/simulation/tinyxml1 depends on CMake and it pulls in CMake 4.

Anyway, I'll just remove tinyxml.

Thanks for the review. I'll wait for a confirmation (#820) before merging.
