FindBLAS
--------
Find Basic Linear Algebra Subprograms (BLAS) library
This module finds an installed Fortran library that implements the
BLAS linear-algebra interface (see http://www.netlib.org/blas/).
The approach follows that taken for the ``autoconf`` macro file,
``acx_blas.m4`` (distributed at
http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).
Input Variables
^^^^^^^^^^^^^^^
The following variables may be set to influence this module's behavior:
``BLA_STATIC``
if ``ON`` use static linkage
``BLA_VENDOR``
If set, checks only the specified vendor, if not set checks all the
possibilities. List of vendors valid in this module:
* ``Goto``
* ``OpenBLAS``
* ``FLAME``
* ``ATLAS PhiPACK``
* ``CXML``
* ``DXML``
* ``SunPerf``
* ``SCSL``
* ``SGIMATH``
* ``IBMESSL``
* ``Intel10_32`` (intel mkl v10 32 bit)
* ``Intel10_64lp`` (intel mkl v10+ 64 bit, threaded code, lp64 model)
* ``Intel10_64lp_seq`` (intel mkl v10+ 64 bit, sequential code, lp64 model)
* ``Intel10_64ilp`` (intel mkl v10+ 64 bit, threaded code, ilp64 model)
* ``Intel10_64ilp_seq`` (intel mkl v10+ 64 bit, sequential code, ilp64 model)
* ``Intel10_64_dyn`` (intel mkl v10+ 64 bit, single dynamic library)
* ``Intel`` (obsolete versions of mkl 32 and 64 bit)
* ``ACML``
* ``ACML_MP``
* ``ACML_GPU``
* ``Apple``
* ``NAS``
* ``Arm``
* ``Arm_mp``
* ``Arm_ilp64``
* ``Arm_ilp64_mp``
* ``Generic``
``BLA_F95``
if ``ON`` tries to find the BLAS95 interfaces
``BLA_PREFER_PKGCONFIG``
if set ``pkg-config`` will be used to search for a BLAS library first
and if one is found that is preferred
Imported targets
^^^^^^^^^^^^^^^^
This module defines the following :prop_tgt:`IMPORTED` target:
``BLAS::BLAS``
The libraries to use for BLAS, if found.
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
``BLAS_FOUND``
library implementing the BLAS interface is found
``BLAS_LINKER_FLAGS``
uncached list of required linker flags (excluding ``-l`` and ``-L``).
``BLAS_LIBRARIES``
uncached list of libraries (using full path name) to link against
to use BLAS (may be empty if compiler implicitly links BLAS)
``BLAS95_LIBRARIES``
uncached list of libraries (using full path name) to link against
to use BLAS95 interface
``BLAS95_FOUND``
library implementing the BLAS95 interface is found
.. note::
C, CXX or Fortran must be enabled to detect a BLAS library.
C or CXX must be enabled to use Intel Math Kernel Library (MKL).
For example, to use Intel MKL libraries and/or Intel compiler:
.. code-block:: cmake
set(BLA_VENDOR Intel10_64lp)
find_package(BLAS)
Hints
^^^^^
Set the ``MKLROOT`` environment variable to a directory that contains an MKL
installation, or add the directory to the dynamic library loader environment
variable for your platform (``LIB``, ``DYLD_LIBRARY_PATH`` or
``LD_LIBRARY_PATH``).
