I'm building trunks for both pcre & pcre2

    /usr/local/bin/pcre-config --version
        8.36
    /usr/local/bin/pcre2-config --version
        10.10-RC1


Chcking for installed libs

    pkg-config libpcre --libs --cflags
        -lpcre


but

    pkg-config libpcre2
        (empty)


Quick look shows, instead

    pkg-config libpcre2-8 --libs --cflags
        -I/usr/local/include -L/usr/local/lib64 -lpcre2-8 


    pkg-config libpcre2-posix --libs --cflags
        -I/usr/local/include -L/usr/local/lib64 -lpcre2-posix 


and

    ls -al /usr/local/lib64/libpcre2*
        -rwxr-xr-x 1 root root  937 Jan 21 09:06 /usr/local/lib64/libpcre2-8.la*
        lrwxrwxrwx 1 root root   19 Jan 21 09:06 /usr/local/lib64/libpcre2-8.so -> libpcre2-8.so.0.0.0*
        lrwxrwxrwx 1 root root   19 Jan 21 09:06 /usr/local/lib64/libpcre2-8.so.0 -> libpcre2-8.so.0.0.0*
        -rwxr-xr-x 1 root root 471K Jan 21 09:06 /usr/local/lib64/libpcre2-8.so.0.0.0*
        -rwxr-xr-x 1 root root  992 Jan 21 09:06 /usr/local/lib64/libpcre2-posix.la*
        lrwxrwxrwx 1 root root   23 Jan 21 09:06 /usr/local/lib64/libpcre2-posix.so -> libpcre2-posix.so.0.0.0*
        lrwxrwxrwx 1 root root   23 Jan 21 09:06 /usr/local/lib64/libpcre2-posix.so.0 -> libpcre2-posix.so.0.0.0*
        -rwxr-xr-x 1 root root  14K Jan 21 09:06 /usr/local/lib64/libpcre2-posix.so.0.0.0*


Should there be just an unversioned 'libpcre2.pc' and /usr/local/lib64/libpcre2.so as well?

I'd suspect upstreams may attempt to default to libpcre2.{pc,so}, as for libpcre.

Or, are there specific reasons NOT to?
