Moodle Problem with libgd compiled.

Dears, i make lib-gd with option(./configure) "--with-gd" but not work. I Download the lib in website and compile this, but my ./configure php displayed a stdout: " If configure fails try --with-vpx-dir=<DIR> If configure fails try --with-jpeg-dir=<DIR> configure: error: png.h not found. " I installing the lib-gd with command #apt-get install php5-gd but i the new configure setting not work to.I find the lib installing in my environment and the lib found in path:/usr/lib/x86_64-linux-gnu/. I want installing this lib easyli with command apt-get and setting the ./configure setting with path for this. My configure: ./configure --prefix=/usr/local/httpd-2.4.23/php --with-apxs2=/usr/local/httpd-2.4.23/bin/apxs \ --with-config-file-path=/usr/local/httpd-2.4.23/php --with-mysql --enable-embedded-mysqli --enable-mbstring \ --enable-bcmath --enable-calendar --enable-dba --enable-exif --enable-ftp --enable-shmop --enable-soap --enable-sockets \ --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-wddx --enable-opcache --enable-zip --enable-pcntl \ --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-zlib-dir=/usr/local/zlib/ \ --with-mhash=/usr/local/mhash --with-gettext=/usr/local/gettext --with-curl=/usr/local/curl-7.52.1/ \ --with-gd=/usr/lib/x86_64-linux-gnu/ --with-jpeg-dir=/usr/lib/x86_64-linux-gnu/ --with-vpx-dir=/usr/lib/x86_64-linux-gnu/ PS: The PHP and Apache work fine, i load wikimedia and phpmyadmin in this enviroment, but my moodle need this gd library.
