 The `/*/occa` backends rely upon the [OCCA](http://github.com/libocca/occa) package to provide cross platform performance.
 To enable the OCCA backend, the environment variable `OCCA_DIR` must point to the top-level OCCA directory, with the OCCA library located in the `${OCCA_DIR}/lib` (By default, `OCCA_DIR` is set to `../occa`).

 Users can pass specific OCCA device properties after setting the CEED resource.
