This is then resolved for the PHP 7.3.
For the PHP 7.4, they have migrated to pkg-config so to override the libpng there:
PNG_CFLAGS=-I/path/to/libpng/include/ \
PNG_LIBS=/path/to/libpng/lib \
./configure --enable-mbstring
In case these should be done somehow differently solved, please send a pull request to check it out
(keep in mind that there are now several extensions already using this, so things need to be
consistent with other extensions). Environment variables might seem a bit weird but you get used to
them also. The migration hasn't been done by me though :). Thank you.

PHP <= 7.3 versions using custom compiled libpng libraries that are installed on custom locations
can be done using: --with-png-dir=/path/to/libpng/usr/local
"PHP 7.4 is using pkg-config so something like this won't work anymore. There the
environment variables will need to be used in front of ./configure command..."

So, what needs to be fixed here? It all works ok. Yes? On prehistoric Linux versions such as Ubuntu
12.04 that aren't supported upstream either anymore, PHP later versions most certainly
won't be possible to compile without major patches and adjustments anyway...

this remains a bug
what is the point of need env vars in case one supplied a pretty clear argument to configure itself
- just set that var implicit instead blindly use pkgcongig when told not to do

Hello, PHP <= 7.3 versions using custom compiled libpng libraries that are installed on custom
locations can be done using:
./configure --with-gd --with-png-dir=/path/to/libpng/usr/local
Note the usr/local attached at the end. The config.m4 file checking for the location
will first check for the custom location provided with the configure option, then go to system
/usr/include directory and so on.

PHP 7.4 is using pkg-config so something like this won't work anymore. There the environment
variables will need to be used in front of ./configure command...

I can reproduce this issue also with 7.2.17 and 7.3.4 versions
