gz-cmake3 and gz-cmake4 (and other gz libraries) not available on Bookworm?

Trying to build gz-tools-vendor, I get the error

--- stderr: gz_tools_vendor                                                                                             CMake Error at CMakeLists.txt:19 (message):                                                                               Could not find either gz-cmake3 or gz-cmake4

Repeated iterations through source installs using vcsdeps.py and rosdep invocations fail to install either, and manually installing via apt does not work. The docs mention that it's available as a binary on Ubuntu systems:

https://gazebosim.org/libs/cmake/#binary-install

Workaround could be to do a source install.

https://github.com/gazebosim/gz-cmake?tab=readme-ov-file#building-from-source

However I need to find out where to do a system install. The package isn't automatically built and installed by Colcon.

Following plain CMake build instructions and simply running cmake .. from the build directory (installs in /usr/local prefix).

This is bigger than gz-cmake.

sdformat_vendor specifically needed gz-cmake3 (which I built and installed by checking out the appropriate branch in the gz-cmake repo) but now we are missing a number of other gz libraries:
