-# - Find BLAS library
-# This module finds an installed fortran library that implements the BLAS
-# linear-algebra interface (see http://www.netlib.org/blas/).
-#
-# Note: This is loosely based off of but a complete re-write of cmake's
-# included FindBLAS.cmake module
-#
-# This module sets the following variables:
-# BLAS_FOUND - set to true if an appropriate BLAS library is found.
-# BLAS_LINKER_FLAGS - list of required linker flags
-# BLAS_LIBRARIES - list of libraries (with paths) to link against
-# BLAS_STATIC - if set then static libraries will be searched for.
-# BLAS_VENDORS - A list of specific vendors implemented BLAS to check
-# for, if not set, checks all known vendors.
-# BLAS_VENDORS_FOUND - A list of located BLAS vendors
-#
-# Also, if set, will use these to guide it's library search:
-# BLAS_${VENDOR}_LIB_DIRS - An additional library dir to search for:
-# Ex:
-# BLAS_ACML_LIB_DIRS=/opt/acml4.4.0/gfortran64/lib
-# BLAS_MKL_LIB_DIRS=/opt/intel/mkl/lib/intel64
-##########
-#
-# Valid values for the BLAS_VENDOR setting are:
-# ACML - Single threaded version of the AMD Core Math Library
-# ACML_MP - Multithreaded version of the AMD Core Math Library using OpenMP
-# See http://developer.amd.com/cpu/Libraries/acml

-# GOTO - Goto BLAS v2

-#
-# OTHER - Any other unsupported BLAS library
-# In order to specify other BLAS libraries, set the following:
-# BLAS_VENDORS = OTHER
-# BLAS_OTHER_LIB_NAMES = A list of libraries to link to
-# BLAS_OTHER_LIB_DIR = Search path for the libraries
-# Ex:
-# set(BLAS_VENDORS OTHER)
-# set(BLAS_OTHER_LIB_NAMES "my_blas;my_blas_support")
-# set(BLAS_OTHER_LIB_DIRS /home/chuck/lib)
-# find_package(BLAS)
