title: Yocto Image build fails because "nothing RPROVIDES libavresample"
body: <p>I am trying to build a custom Yocto image based on fsl-image-gui for my iMX6 based board SECO A62J. I use Hob to do this.</p>
  
  <p>After having selected my machine, my layers and my image, I custom my packages list by adding chromium. This automatically selects libexif and libav which are Chromium dependencies. The build of the packages is successful</p>
  
  <p>The last step is the build of the image itself, and this is where my problem appears. I select the packages I want to include in my image, including Chromium, libexif and libav (and its dependencies).</p>
  
  <p>And I got those errors :</p>
  
  <blockquote>
    <p>Nothing RPROVIDES 'libavresample' (but
    /home/adrien/fsl-release-bsp/build_anna/recipes/images/fsl-image-gui-edited-20170131-144607.bb RDEPENDS on or otherwise requires it)</p>
  </blockquote>
  
  <p>and</p>
  
  <blockquote>
    <p>Required build target 'fsl-image-gui-edited-20170131-144607' has no
    buildable providers. Missing or unbuildable dependency chain was:
    ['fsl-image-gui-edited-20170131-144607', 'libavresample']</p>
  </blockquote>
  
  <p>However, the library libavresample.so is built successfully and can be found  under my build directory in sysroots/"machine_name"/usr/lib/</p>
  
  <p>Why Yocto can't find and include this library in my image, What am I missing here?</p>
