  64 # built normally. However, when we install it, they need to have the same name.
  65 # To handle this we add a small bit of shell logic. Note that the mv bit is
  66 # explicitly ignored and instead we do a final check to make sure we have
  67 # something called cpp at the very end which will either be because of install
  68 # or because of the later mv.
