# --------
#
# 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
#
# ######### ## List of vendors (BLA_VENDOR) valid in this module #
# Goto,OpenBLAS,ATLAS PhiPACK,CXML,DXML,SunPerf,SCSL,SGIMATH,IBMESSL,
# Intel10_32 (intel mkl v10 32 bit),Intel10_64lp (intel mkl v10 64 bit,
# lp thread model, lp64 model), # Intel10_64lp_seq (intel mkl v10 64
# bit,sequential code, lp64 model), # Intel( older versions of mkl 32
# and 64 bit), ACML,ACML_MP,ACML_GPU,Apple, NAS, Generic C/CXX should be
# enabled to use Intel mkl
