[Bug 1792544] Re: demotion of pcre3 in favor of pcre2

[Andreas Hasenack]

I've seen the wget debian change, but just switching builddeps from pcre3-dev to pcre2-dev and rebuilding isn't enough. The package ends up not finding pcre and doesn't enable it:
checking for PCRE... no
checking pcre.h usability... no
checking pcre.h presence... no
checking for pcre.h... no
...
  Libs:              -luuid -lidn2 -lnettle -lgnutls -lz -lpsl 

So while the package builds, it's not using pcre.

I tried to switch apache, and while I could make it find pcre2-config and use it, pcre2 has different libraries than pcre3:
pcre3-config --libs: -lpcre
pcre2-config --libs: no such parameter

In pcre2, we have --libs8, --libs-posix, --libs32 and --libs16, but no
--libs. Is this a bug in pcre2-config?

Any quick tips about this before I dig in further?
