Interesting format, but we prefer consistency, you can see this in git history.
Bugzilla ID: xxx

This can be caught by running the devtools/check-git-log.sh script.

I am no meson expert, but I'd say you can put a subdir_done() if your
check is false and then you don't need to check the build variable
later.
Besides, you can most likely do this check at the top of this file
alongside "depends".

Unrelated change + whitespace damage after.
