From: Gwenhael Goavec-Merou <gwenhael.goavec-merou at trabucayre.com>
armadillo can use clapack or lapack as BLAS and LAPACK provider.
This patch
- adds two hidden variable to check dependencies/requirement for each of them
- a choice to select wich implementation to use, by default use on clapack
when it's possible, else lapack
