FindBLAS

Find Basic Linear Algebra Subprograms (BLAS) library

This module finds an installed Fortran library that implements the BLAS linear-algebra interface (see http://www.netlib.org/blas/).

The approach follows that taken for the autoconf macro file, acx_blas.m4 (distributed at http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).

The libraries to use for BLAS, if found.

Result Variables

This module defines the following variables:

BLAS_FOUND

library implementing the BLAS interface is found

BLAS_LINKER_FLAGS

uncached list of required linker flags (excluding -l and -L).

BLAS_LIBRARIES

uncached list of libraries (using full path name) to link against to use BLAS (may be empty if compiler implicitly links BLAS)

BLAS95_LIBRARIES

uncached list of libraries (using full path name) to link against to use BLAS95 interface

find_package(BLAS)

Hints

MKLROOT

New in version 3.15.

Set this environment variable to a directory that contains an MKL installation, or add the directory to the dynamic library loader environment variable for your platform (LIB, DYLD_LIBRARY_PATH or LD_LIBRARY_PATH).
