The upgrade of cmake to v3.6.0 broke this build. HDF5 now can
only be found if hdf5-cpp is used as buildInput.
However the upgrade made it possible to remove a patch:
CMake can now find openblas on its own.
- Remove unused dependencies atlas/blas
- Add hdf5/superlu dependency (As superlu needs openblasCompat, we also use it here.)
- Add support for darwin
- Make use of OpenBLAS-LAPACK in armadillo
OpenBLAS (confusingly) contains LAPACK already by default, so we simply use OpenBLAS when searching for LAPACK.
The better solution would be for armadillo to use cmake built in FindBLAS/FindLAPACK which both would find OpenBLAS.
