Per mesonbuild/meson#15297 there was a regression in meson 1.10.1 which results in it incorrectly passing soversion and version kwargs to cmake subprojects. We have pinned meson versions to 1.9.1 until this bug is resolved upstream. It looks like something has been pulled in already so likely meson version 1.10.2 or 1.11.0 will resolve this. I will close this issue when it is resolved.
