Fix meson build with -Duuid=ossp when using version older than 0.60

michaelpq · michaelpq · commit 5f565b0aee90 · 2025-09-22T08:03:25.000+09:00
The package for the UUID library may be named "uuid" or "ossp-uuid", and meson.build has been using a single call of dependency() with multiple names, something only supported since meson 0.60.0. The minimum version of meson supported by Postgres is 0.57.2 on HEAD, since f039c22, and 0.54 on stable branches down to 16.
