You need to export the variable before it can be seen by programs other 
than your shell.

I'm not familiar with fish shell, but there's a tutorial here:
  http://fishshell.com/docs/current/tutorial.html

It looks like you have to say this:

   > set -x CCACHE_DIR /tmp/ccache

You can check if the export was successful with the "env" command.

Hope that helps
