title: Bitbake error - Nothing RPROVIDES
body: <p>I would to split and application into multiple packages. Basically I just would like to add an other one which could be build by using a specific image.</p>
  
  <p>Inside the .bb file associated to the application I added : </p>
  
  <pre><code>SRC_URI = " \
            ...
            file://api.conf \
            file://script.sh \
            "
  
  PACKAGES =+ "${PN} ${PN}-tools"
  
  FILES_${PN}-tools = "${bindir}/mrvl/tools/script.sh \
                       ${sysconfdir}/mrvl/api.conf \
                      "
  </code></pre>
  
  <p>Then, I added the following line in my bb image test</p>
  
  <pre><code>IMAGE_INSTALL += " mrvl-tools"
  </code></pre>
  
  <p>I am using the command bitbake image-test which returns :</p>
  
  <pre><code>ERROR: Nothing RPROVIDES 'mrvl-tools' (but /home/usr/../image-test.bb RDEPENDS on or otherwise requires it)
  NOTE: Runtime target 'mrvl-tools' is unbuildable, removing...
  Missing or unbuildable dependency chain was: ['mrvl-tools']
  ERROR: Required build target 'image-test' has no buildable providers.

  </code></pre>
  
  <p>I followed the same definition of the bluez5-obex package and IMAGE_ISTALL += " bluez5-obex" works..</p>
  
  <p>What I forget ?</p>
