* \warning This wrapper is only for the 4.x versions of SuperLU. The 3.x and 5.x versions are not supported.
* \warning This wrapper requires at least versions 4.0 of SuperLU. The 3.x versions are not supported.

* \warning When including this module, you have to use SUPERLU_EMPTY instead of EMPTY which is no longer defined because it is too polluting.
