title: Semantic UI build not overwriting variables with site global variables
body: <p>I'm getting a strange problem with Semantic UI and I have no idea from where it's coming from.</p>
  
  <p>I have set only the <code>@primaryColor</code> in the <code>site.variables</code> which is at <code>src/site/globals</code> folder but every time I run the Gulp <code>build</code> task from Semantic UI, it fills the <code>dist</code> folder with the standard Semantic files. It completely ignores the global variables I have set in my <code>site</code> folder.</p>
  
  <p>Any ideas from where this problem could be coming?</p>
  
  <p>Thanks in advance!</p>
  
  <p>Cheers,</p>
  
  <p>Fabio.</p>
