Hello Simon,

Now I'm on 47ab553178eb00d02ba9588ed1f7df44fb2f7c4c guix commit and
still have the problem:
----begin-----------------------------------------------------------
$ guix build x265 -d
3,9 MB will be downloaded:
   /gnu/store/1h81psijhx3l8p88ds66q7a001rgvcl2-x265-3.5
   /gnu/store/4zw8h8za4z1cg4k5iz5lha6v1s9wzwkz-x265-3.5-static

----end-------------------------------------------------------------

Moreover, since then I have realized that the problem is not specific
to packages with cmake build system but concerns all packages with
multiple outputs.

Your Guix installation is 92 days old. Probably this is the reason why
you wasn't able to reproduce the problem. As far as I remember this
problem have arisen since the latest core packages update.
