Comment:
Note that building for musl will require patching. One example was adding

```
if BACKWARD_HAS_BACKTRACE_SYMBOL == 1
#        include <dlfcn.h>
#    endif
```
in `gz-tools/src/vendor/backward.hpp` and another file.

I fixed some more problems, but my storage ran out so I couldn't proceed.

Comment:
I used separate versions for each component because Gazebo comes as distributions. Gazebo Garden is separate from Gazebo Harmonic.

The version of ROS also only works with select versions of Gazebo, using `ros_gz` (packaged as `ros-{ROS_DISTRO}-ros-gz`). For Gazebo Harmonic, ROS 2 Jazzy is the official pairing. But the release will only be on May 23, 2024.

ROS 2 Iron and ROS 2 Humble can work with Gazebo Garden and Gazebo Harmonic, however the builds of `ros-iron-ros-gzgarden`, `ros-iron-ros-gzharmonic`, `ros-humble-ros-gzgarden` and `ros-humble-ros-gzharmonic` are unofficial and separately built.

please don't spam package requests. make a single one for a package you want, and if it is added, its dependencies will be too.

I once heard that we had to split dependencies ([here](https://github.com/void-linux/void-packages/pull/41185#discussion_r1055638769)).. that's why I made separate requests.

Edit: I guess I misunderstood it to mean I should also make multiple requests.

Comment:
Since `ros_gz` bridge depends on the ROS version and Gazebo version, if we package multiple Gazebo and ROS versions, they we will have to make `ros_gz` packages for all of them.

Instead, all those who want `ros_gz` aside from the official pairings (as mentioned in the [README](https://github.com/gazebosim/ros_gz)) should install it in their own overlay workspaces using `rosdep install` and `colcon build`.
