# - Find BLAS library
|
|
# This module finds an installed fortran library that implements the BLAS
|
|
# linear-algebra interface (see http://www.netlib.org/blas/).
|
|
# The list of libraries searched for is taken
|
|
# from the autoconf macro file, acx_blas.m4 (distributed at
|
|
# http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).
|
|
#
|
|
# This module sets the following variables:
|
|
# BLAS_FOUND - set to true if a 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
|
|
# BLAS95_LIBRARIES - uncached list of libraries (using full path name)
|
|
# to link against to use BLAS95 interface
|
|
# BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
|
|
# is found
|
|
# BLA_STATIC if set on this determines what kind of linkage we do (static)
|
|
# BLA_VENDOR if set checks only the specified vendor, if not set checks
|
|
# all the possibilities
|
|
# BLA_F95 if set on tries to find the f95 interfaces for BLAS/LAPACK
|
