-Subject: [PATCH] meson: Allow fallback & static build of pcre subproject
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Using `allow_fallback: false` on the first check for libpcre
-was unnecessary, as `required: false` already disables using
-fallbacks. `allow_fallback: false` meant that
-`--force-fallback-for` couldn’t work. This commit fixes that.
-
-Also allow the fallback libpcre to be built statically so it
-can be linked into GLib.
-
-Helps: #3025
