unrecognized --with-jpg-dir and --with-png-dir

[llslim]

I came accross the same issue. I could repair it by changing the line

docker-php-ext-configure gd --with-freetype-dir=/usr --with-jpeg-dir=/usr --with-png-dir=/usr

into

docker-php-ext-configure gd --with-freetype --with-jpeg

I could not find a --with-png option, but png resizing worked in my case. So maybe png support is a built in default as of PHP 7.4.

A further change I had to make was to include the libonig-dev apt package in order to compile the pdo module.

It's strange that the README.md and the description on Docker Hub don't give examples how to compile pdo and gd properly on PHP 7.4, but only give it for PHP 7.2 (which still works for 7.3 as well).
