This FTBFS appears with swig 4.5, reverting back to 4.4 makes the issue
disappear.
Maybe it's time to let Ogre-1.12 go
More context:
The upstream Ogre 1.12 branch is dead, the final update to v1.12 was
released in August 2021. It has been superseded by OGRE 13, which was
itself superseded by OGRE-14 in 2023.
I personally would like to remove src:ogre-12 from Debian before the
Forky release.
There is only one r-dep in the Debian that still use v1.12, see bug
https://bugs.debian.org/1139454
Cheers,
Sébastien
