Find Linear Algebra PACKage (LAPACK) library
|
|
|
|
This module finds an installed Fortran library that implements the
|
|
`LAPACK linear-algebra interface`_.
|
|
|
|
At least one of the ``C``, ``CXX``, or ``Fortran`` languages must be enabled.
|
|
|
|
.. _`LAPACK linear-algebra interface`: https://netlib.org/lapack/
|
|
|
|
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/LAPACK95 interfaces
|
|
|
|
``BLA_PREFER_PKGCONFIG``
|
|
.. versionadded:: 3.20
|
|
|
|
if set ``pkg-config`` will be used to search for a LAPACK library first
|
|
and if one is found that is preferred
|
|
|
|
``BLA_PKGCONFIG_LAPACK``
|
|
.. versionadded:: 3.25
|
|
|
|
If set, the ``pkg-config`` method will look for this module name instead of
|
|
just ``lapack``.
|
|
|
|
|
|
``BLA_SIZEOF_INTEGER``
|
|
.. versionadded:: 3.22
|
|
|
|
Specify the BLAS/LAPACK library integer size:
|
|
|
|
``4``
|
|
Search for a BLAS/LAPACK with 32-bit integer interfaces.
|
|
``8``
|
|
Search for a BLAS/LAPACK with 64-bit integer interfaces.
|
|
``ANY``
|
|
Search for any BLAS/LAPACK.
|
|
Most likely, a BLAS/LAPACK with 32-bit integer interfaces will be found.
|
|
|
|
Imported targets
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This module defines the following :prop_tgt:`IMPORTED` targets:
|
|
|
|
``LAPACK::LAPACK``
|
|
.. versionadded:: 3.18
|
|
|
|
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
|
|
|
|
Intel MKL
|
|
^^^^^^^^^
|
|
|
|
To use the Intel MKL implementation of LAPACK, 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(LAPACK)
|
|
|
|
In order to build a project using Intel MKL, and end user must first
|
|
establish an Intel MKL environment. See the :module:`FindBLAS` module
|
|
section on :ref:`Intel MKL` for details.
