Find Linear Algebra PACKage (LAPACK) library
|
||
|
|
||
|
This module finds an installed Fortran library that implements the
|
||
|
LAPACK linear-algebra interface (see http://www.netlib.org/lapack/).
|
||
|
|
||
|
The approach follows that taken for the ``autoconf`` macro file,
|
||
|
``acx_lapack.m4`` (distributed at
|
||
|
http://ac-archive.sourceforge.net/ac-archive/acx_lapack.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:
|
||
|
|
||
|
* ``OpenBLAS``
|
||
|
* ``FLAME``
|
||
|
* ``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``
|
||
|
* ``Apple``
|
||
|
* ``NAS``
|
||
|
* ``Arm``
|
||
|
* ``Arm_mp``
|
||
|
* ``Arm_ilp64``
|
||
|
* ``Arm_ilp64_mp``
|
||
|
* ``Generic``
|
||
|
|
||
|
``BLA_F95``
|
||
|
if ``ON`` tries to find the BLAS95/LAPACK95 interfaces
|
||
|
|
||
|
Imported targets
|
||
|
^^^^^^^^^^^^^^^^
|
||
|
|
||
|
This module defines the following :prop_tgt:`IMPORTED` target:
|
||
|
|
||
|
``LAPACK::LAPACK``
|
||
|
The libraries to use for LAPACK, if found.
|
||
|
|
||
|
Result Variables
|
||
|
^^^^^^^^^^^^^^^^
|
||
|
|
||
|
This module defines the following variables:
|
||
|
|
||
|
``LAPACK_FOUND``
|
||
|
library implementing the LAPACK interface is found
|
||
|
``LAPACK_LINKER_FLAGS``
|
||
|
uncached list of required linker flags (excluding ``-l`` and ``-L``).
|
||
|
``LAPACK_LIBRARIES``
|
||
|
uncached list of libraries (using full path name) to link against
|
||
|
to use LAPACK
|
||
|
``LAPACK95_LIBRARIES``
|
||
|
uncached list of libraries (using full path name) to link against
|
||
|
to use LAPACK95
|
||
|
``LAPACK95_FOUND``
|
||
|
library implementing the LAPACK95 interface is found
|
||
|
|
||
|
.. note::
|
||
|
|
||
|
C, CXX or Fortran must be enabled to detect a BLAS/LAPACK 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:
|
