# - 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
#
# ACCELERATE - Apple's Accelerate library
# See http://developer.apple.com/performance/accelerateframework
#
# ATLAS - Automatically Tuned Linear Algebra Software
# See http://math-atlas.sourceforge.net/
#
# GOTO - Goto BLAS v2
# See http://www.tacc.utexas.edu/tacc-projects/gotoblas2
#
# GENERIC - Search for a generic libblas
#
# VECLIB - HP's Math Library: VECLIB
#
# ESSL - IBM's Engineering and Scientific Subroutine Library
# ESSLSMP - IBM's Engineering and Scientific Subroutine Library (smp)
# See http://www-03.ibm.com/systems/software/essl/
#
# MKL_RT - Intel Math Kernel Library (dynamic runtime interface)
# MKL_SEQ - Intel Math Kernel Library (sequential interface)
# MKL - Intel Math Kernel Library (multi-threaded interface)
# See http://software.intel.com/en-us/intel-mkl
#
# PERFLIB - Oracle Performance Library (formerly Sun Performance Library)
# SUNPERF - Oracle Performance Library (formerly Sun Performance Library)
# See http://www.oracle.com/technetwork/server-storage/solarisstudio
#
# SCSL - SGI's Scientific Computing Software Library
# See http://www.sgi.com/products/software/irix/scsl.html
#
# 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)
