--FindLapack
------------
--
--* Michael Hirsch, Ph.D. www.scivision.dev
--* David Eklund
--
--Let Michael know if there are more MKL / Lapack / compiler combination you want.
--Refer to https://software.intel.com/en-us/articles/intel-mkl-link-line-advisor
--
--Finds LAPACK libraries for C / C++ / Fortran.
--Works with Netlib Lapack / LapackE, Atlas and Intel MKL.
--Intel MKL relies on having environment variable MKLROOT set, typically by sourcing
--mklvars.sh beforehand.
--
--Why not the FindLapack.cmake built into CMake? It has a lot of old code for
--infrequently used Lapack libraries and is unreliable for me.
--
--Tested on Linux, MacOS and Windows with:
--* GCC / Gfortran
--* Clang / Flang
--* Intel (icc, ifort)
--* Cray
--
--
--Parameters
--^^^^^^^^^^
--
--COMPONENTS default to Netlib LAPACK / LapackE, otherwise:
--
--``MKL``
--  Intel MKL -- sequential by default, or add TBB or MPI as well
--``MKL64``
--  MKL only: 64-bit integers  (default is 32-bit integers)
--``TBB``
--  Intel MPI + TBB for MKL
--``AOCL``
--  AMD Optimizing CPU Libraries
--
--``LAPACKE``
--  Netlib LapackE for C / C++
--``Netlib``
--  Netlib Lapack for Fortran
--``OpenBLAS``
--  OpenBLAS Lapack for Fortran
--
--``LAPACK95``
--  get Lapack95 interfaces for MKL or Netlib (must also specify one of MKL, Netlib)
--
--``STATIC``
--  Library search default on non-Windows is shared then static. On Windows default search is static only.
--  Specifying STATIC component searches for static libraries only.
--
--
--Result Variables
--^^^^^^^^^^^^^^^^
--
--``LAPACK_FOUND``
--  Lapack libraries were found
--``LAPACK_<component>_FOUND``
--  LAPACK <component> specified was found
--``LAPACK_LIBRARIES``
--  Lapack library files (including BLAS
--``LAPACK_INCLUDE_DIRS``
--  Lapack include directories (for C/C++)
--
