body: <p>I  tried to build the BSP for v3msk (linux based embedded system) on Ubuntu 18.04 following the link:</p>

  <p>I used Yocto v3.21.0</p>
  
  <p>The local.conf I used is available here <a href="https://pastebin.com/UyBGzQ2J" rel="nofollow noreferrer">https://pastebin.com/UyBGzQ2J</a></p>
  
  <p>I tried adding x11 to distro features.</p>
  
  <pre><code>DISTRO_FEATURES_append = " x11"
  </code></pre>
  
  <p>I ran </p>
  
  <pre><code>bitbake core-image-x11 
  </code></pre>
  
  <p>and I expect it to build yocto images with X11. </p>
  
  <p>I got error :</p>
  
  <pre><code>ERROR: Nothing PROVIDES 'core-image-x11'
  core-image-x11 was skipped: missing required distro feature 'x11' (not in 
  DISTRO_FEATURES)
  </code></pre>
  
  <p>What could be missing in local.conf?</p>
