rpicamsrc Gstreamer 1.18.2 compilation error

[horai]

I upgraded the raspberrypi-dev Raspbian package with up-to-date
https://github.com/raspberrypi/userland build. The compilation failed again,
but errors are different, therefore I assume a specific build of Raspbian
userland, must be present, but I initially used the one which is coming
preinstalled with Raspbian from repository.

If so, could anyone help me find out which build is necessary for rpicamsrc
to pass the build? I don't mind installing rpicamsrc from sources and
exclude it from 1.18.2 compilation, but I would rather have official
inclusion of rpicamsrc sources in Gstreamer build which could bring some
benefits over externally compiled plugin
