PCRE ("Perl Compatible Regular Expressions") is a required dependency
for libguestfs, guestfs-tools and virt-v2v. We use it extensively
throughout the code for regular expression stuff, and even maintain
our own OCaml bindings.
The original PCRE (v1) was deprecated upstream a few years ago. It's
now only maintained for critical bugs.
Therefore I have migrated everything over to PCRE2 -- quite a
significant change actually. So you'll need to adjust your
dependencies accordingly. PCRE2 seems to be as widely available as
PCRE (v1) so this shouldn't be a problem, although let me know if it
causes any issues.
