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_STATICif
ONuse static linkageBLA_VENDORSet to one of the BLAS/LAPACK Vendors to search for BLAS only from the specified vendor. If not set, all vendors are considered.
BLA_F95if
ONtries to find the BLAS95/LAPACK95 interfacesBLA_PREFER_PKGCONFIGNew in version 3.20.
if set
pkg-configwill be used to search for a LAPACK library first and if one is found that is preferredBLA_PKGCONFIG_LAPACKNew in version 3.25.
If set, the
pkg-configmethod will look for this module name instead of justlapack.BLA_SIZEOF_INTEGERNew in version 3.22.
Specify the BLAS/LAPACK library integer size:
4Search for a BLAS/LAPACK with 32-bit integer interfaces.
8Search for a BLAS/LAPACK with 64-bit integer interfaces.
ANYSearch for any BLAS/LAPACK. Most likely, a BLAS/LAPACK with 32-bit integer interfaces will be found.
Imported targets¶
This module defines the following IMPORTED targets:
LAPACK::LAPACKNew in version 3.18.
The libraries to use for LAPACK, if found.
Result Variables¶
This module defines the following variables:
LAPACK_FOUNDlibrary implementing the LAPACK interface is found
LAPACK_LINKER_FLAGSuncached list of required linker flags (excluding
-land-L).LAPACK_LIBRARIESuncached list of libraries (using full path name) to link against to use LAPACK
LAPACK95_LIBRARIESuncached list of libraries (using full path name) to link against to use LAPACK95
LAPACK95_FOUNDlibrary 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.
