title: How to build Qt5 sdk in Yocto for Raspberry PI?
body: <p>I am trying to build meta-toolchain-qt5. However, I am getting these errors. I am following the guide - 
  <a href="http://wiki.wandboard.org/index.php/Building_Qt5_using_yocto_on_Wandboard" rel="nofollow noreferrer">Guide Qt5 build</a></p>
  
  <p>Here are the things I have done so far - </p>
  
  <p>Inside poky - </p>
  
  <pre><code>$git clone https://github.com/meta-qt5/meta-qt5.git
  </code></pre>
  
  <p>Afterwards, I have changed </p>
  
  <p>conf/bblayers.conf </p>
  
  <pre><code>POKY_BBLAYERS_CONF_VERSION = "2"
  
  BBPATH = "${TOPDIR}"
  BBFILES ?= ""
  
  BBLAYERS ?= " \

  <p>Next, I have appended in the conf/local.conf</p>
