--------
Find Basic Linear Algebra Subprograms (BLAS) library
This module finds an installed Fortran library that implements the
`BLAS linear-algebra interface`_.
At least one of the ``C``, ``CXX``, or ``Fortran`` languages must be enabled.

Input Variables
^^^^^^^^^^^^^^^
The following variables may be set to influence this module's behavior:
``BLA_STATIC``
if ``ON`` use static linkage
``BLA_VENDOR``
Set to one of the :ref:`BLAS/LAPACK Vendors` to search for BLAS only
from the specified vendor. If not set, all vendors are considered.
``BLA_F95``
if ``ON`` tries to find the BLAS95 interfaces
``BLA_PREFER_PKGCONFIG``
.. versionadded:: 3.11
if set ``pkg-config`` will be used to search for a BLAS library first
and if one is found that is preferred
Imported targets
^^^^^^^^^^^^^^^^

.. _`Intel MKL`:
Intel MKL
^^^^^^^^^
To use the Intel MKL implementation of BLAS, a project must enable at least
one of the ``C`` or ``CXX`` languages. Set ``BLA_VENDOR`` to an Intel MKL
variant either on the command-line as ``-DBLA_VENDOR=Intel10_64lp`` or in
project code:
.. code-block:: cmake
set(BLA_VENDOR Intel10_64lp)
find_package(BLAS)
In order to build a project using Intel MKL, and end user must first
establish an Intel MKL environment:
Intel oneAPI
Source the full Intel environment script:
.. code-block:: shell
. /opt/intel/oneapi/setvars.sh
Or, source the MKL component environment script:
.. code-block:: shell
. /opt/intel/oneapi/mkl/latest/env/vars.sh
Intel Classic
Source the full Intel environment script:
.. code-block:: shell
. /opt/intel/bin/compilervars.sh intel64
Or, source the MKL component environment script:
.. code-block:: shell
. /opt/intel/mkl/bin/mklvars.sh intel64
The above environment scripts set the ``MKLROOT`` environment variable
to the top of the MKL installation. They also add the location of the
runtime libraries to the dynamic library loader environment variable for
your platform (e.g. ``LD_LIBRARY_PATH``). This is necessary for programs
linked against MKL to run.
.. note::
As of Intel oneAPI 2021.2, loading only the MKL component does not
make all of its dependencies available. In particular, the ``iomp5``
library must be available separately, or provided by also loading
the compiler component environment:
.. code-block:: shell
. /opt/intel/oneapi/compiler/latest/env/vars.sh
