title: How to import a Cmdlet from a DLL
body: <p>Is it possible to import and invoke a Cmdlet from a DLL that is not in the PATH directories?</p>
  
  <p>I want to write a build script with powershell that is able to compress the results. Therefore I found <a href="http://thomasfreudenberg.com/blog/archive/2013/04/07/7-zip-for-powershell.aspx" rel="noreferrer">7Zip4Powershell</a> Cmdlets (<a href="https://github.com/thoemmi/7Zip4Powershell" rel="noreferrer">Source</a>), but I am unable to invoke them.</p>
