I get it, I chose that because of its lack of need to rebuild, while the
simpler rebuild variant would indeed require a rebuild (here a copy).
It's not that big of a subject here, these libraries are not super heavy
themselves so I'll change that.

I still like this solution for this reason, and I think this could be
applied for some other packages I've worked on (e.g. libreoffice is very
tricky to separate the build into steps, because some of its build
elements require the whole package, but it can be split at the end).
Agree to keep this as an exception when the alternative is really more
complex though, or when the build is very heavy (and thus making a copy
despite additional complexity makes sense).
