title: How to install ZF2 component without Composer
body: <p>I have tried to install both ZendPdf and TCPDF into ZF2 using Composer without success. <br>
  Software is installed and autoload files are written but nothing works, ZF can't see them.<br>
  <br>
  Which files do I need to edit in order to manually install TCPDF library so that it autoloads? <br>
  I have found lots of similar questions in StackOverflow but not many working answers that don't involve Composer.</p>
