title: Cant install mPDF package using Composer PHP - requires ext-gd
body: <p>I am trying to install mPDF package and when I run the command <code>composer require mpdf/mpdf</code> it displays these errors:</p>
  
  <pre><code>    Your requirements could not be resolved to an installable set of packages.
  
    Problem 1
      - The requested PHP extension ext-gd * is missing from your system. Install or enable PHP's gd extension.
    Problem 2
      - mpdf/mpdf v8.0.2 requires ext-gd * -&gt; the requested PHP extension gd is missing from your system.
      - mpdf/mpdf v8.0.1 requires ext-gd * -&gt; the requested PHP extension gd is missing from your system.
      - mpdf/mpdf v8.0.0 requires ext-gd * -&gt; the requested PHP extension gd is missing from your system.
      - Installation request for mpdf/mpdf ^8.0 -&gt; satisfiable by mpdf/mpdf[v8.0.0, v8.0.1, v8.0.2].
  
    To enable extensions, verify that they are enabled in your .ini files:
      - C:\php\php.ini
    You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
  
  Installation failed, reverting ./composer.json to its original content.
  </code></pre>
  
  <p>Can I just download mPDF and place it in my working repo? Or do I have to use Composer to install it?
  I tried to search for this errors and I think the only solution would be to install chocolatey and then use it to install <code>php7.3.2-gd</code> , but if there is a better solution please let me know!</p>
