# - 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
STYLE: fix typos in the docs Alex
