title: Create tar archive with Cmake
body: <p>I have used the *_OUTPUT_PATH variables in my CMakeLists.txt file to specify specific locations for my binaries and library files, and that seems to be working "automatically"</p>
  
  <p>I would like as part of a "build" for one final step to happen, which is to create a tarball of the binaries that output directory.</p>
  
  <p>What do I need to add to create a tar?</p>
