Do you think this is a bug that should be reported?

Oh, I don't know. I assumed it was an artefact from Guix build
environment set-up, and that building out-of-tree was considered weird
or something. Never used cmake.
Should the script use some cmake environment variable instead?
Kind regards,

Maybe you're right. Unlike the gnu-build-sytem, the cmake-build-system
seems to create a 'build/' directory adjacent to the unpacked source
code.
It's not a big deal one way or the other.

Yes, I think in cmake's land, the recommended way is to build in a directory
outside of the source code , generally at the same level than the source tree
which can be made read-only...

Thanks for the clarification, Vincent.
I think the package is ready :)
