title: Yocto/Bitbake Path Variable for Append File Directory
body: <p>So I am using a .bbappend file in a layer I have created and in that layer I also have some additional local files that I want to install.</p>
  
  <p>The problem is I am not sure what the Yocto variable is that correctly represents the directory where my bbappend file is located. Variables like "THISDIR" end up pointing to the original recipe directory - not the append one in my layer. How can I best do this without putting some type of absolute path?</p>
