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
