old embedded pcre version

[leegarrett]

src/pcre/* contains an antique pcre (3?) version, that also gets statically linked into the binary during build. I'll see if I can update it to current versions, and also change the build to preferentially use the system version.

I'll see if I can get a working PR done today.

FYI, this is (with the missing man page) the only remaining blocker for including mvdsv in Debian.

[leegarrett]

This is apparently fixed in newer builds when libpcre3-dev is installed on the system.

This should be reopened because the build system has moved from meson to cmake with mvdsv 0.35. cmake links against internal pcre and does not offer the option of linking against system pcre.

This might also be a blocker in OpenBSD ports, so thanks for raising this issue about using the ancient bundled pcre.

[tcsabina]

You are right.
Either we should update the contained pcre, or give the option to use the system provided pcre stuff.

Willing to contribute? ;)

@tcsabina I've added a PR #101 that searches for pcre library and links against it if found.
if you'd like to have a look? Apologies if it is pretty rough. This is my first time doing much of anything with CMake.

@tcsabina I think PR #101 should be in a good enough state to merge now?
Let me know if I need to change anything. Thanks!

pcre is abandoned. Please move to pcre2, which is pcre's successor.
