FindLAPACK

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.

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 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

New in version 3.20.

if set pkg-config will be used to search for a LAPACK library first and if one is found that is preferred

Imported targets

This module defines the following IMPORTED targets:

LAPACK::LAPACK

New in version 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:

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 FindBLAS module section on Intel MKL for details.
