+Subject: [PATCH] [cmake] Simplify zstd find logic, and support pre-existing
+ zstd target
+
+Some deduplication work on the zstd required/if-available logic. Also
+adds support for pre-existing `zstd::libzstd` which is useful for
+projects that bundle their own zstd in a way that doesn't get caught by
+`CONFIG`
