Description:
------------
Upgrading from PHP 7.3 to 7.4.  I have pcre2 10.33 installed in /usr/local.  I previously specified --with-pcre-regex=/usr/local.  Since this option is removed in php 7.4 I changed it to --with-external-pcre=/usr/local and the configure is now failing. 

I receive the following messages  

checking for libpcre2-8 >= 10.30... no
configure: error: Package requirements (libpcre2-8 >= 10.30) were not met:

No package 'libpcre2-8' found




Expected result:
----------------
I have pcre2 installed in /usr/local.   php 7.3. configure used it with --with-pcre-regex=/usr/local  however --with-external-pcre2=/usr/local in php 7.4 does not work.

-/ocnigure --hepp don#t state that --with-external-pcre is supüposed to take an agrument! you are only switching between bundeled or system library and for everything else PKG_CONFIG_PATH is your freind since you are not using a system library

Indeed, it is like @bugreports stated above: --with-external-pcre
is just a switch; the actual path configuration is done via
pkg-config and can be configured by setting PKG_CONFIG_PATH.

Changing to doc bug, because that is not yet documented in the
PCRE installation chapter[1].

thank you.   I set --with-external-pcre=yes   and added  export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH  to my build script and PHP is built successfully.
