FindLAPACK¶
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¶

 - New in version 3.6: - OpenBLASsupport.- New in version 3.11: - FLAMEsupport.- New in version 3.13: Added ILP64 MKL variants ( - Intel10_64ilp,- Intel10_64ilp_seq).- New in version 3.17: Added single dynamic library MKL variant ( - Intel10_64_dyn).- New in version 3.18: Arm Performance Libraries support ( - Arm,- Arm_mp,- Arm_ilp64,- Arm_ilp64_mp).- New in version 3.19: - FlexiBLASsupport.- New in version 3.20: Elbrus Math Library support ( - EML,- EML_mt).
- BLA_F95
- if - ONtries to find the BLAS95/LAPACK95 interfaces
- BLA_PREFER_PKGCONFIG
- New in version 3.20. - if set - pkg-configwill be used to search for a LAPACK library first and if one is found that is preferred
Imported targets¶
New in version 3.18.
This module defines the following 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 - -land- -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:
set(BLA_VENDOR Intel10_64lp)
find_package(LAPACK)
