When building with the minimal moduleset on Ubuntu 22.04, I got the following build error:

```
Found CMake: /usr/bin/cmake (3.22.1)

Ubuntu 22.04 satisfies all the required dependencies provided by the GStreamer moduleset through system libraries. In theory, the pkg-config tag should prevent installing the modules provided by GStreamer if a more up-to-date version of that package is available through system dependencies. However, some modules lack a .pkg file so it's not possible to do this in all cases.

An alternative solution could be to restore the former jhbuild-minimal moduleset and add a new one which also includes the gstreamer modules. Those systems that cannot satisfy gstreamer dependencies through system libraries can use this new minimal-plus-gstreamer moduleset.
