#
# - 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_COMPILER_FLAGS - uncached list of required compiler flags (including -I for mkl headers).
# 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
# BLAS_VENDOR_FOUND stores the BLAS vendor found
# BLA_F95 if set on tries to find the f95 interfaces for BLAS/LAPACK
# The user can give specific paths where to find the libraries adding cmake
# options at configure (ex: cmake path/to/project -DBLAS_DIR=path/to/blas):
# BLAS_DIR - Where to find the base directory of blas
# BLAS_INCDIR - Where to find the header files
# BLAS_LIBDIR - Where to find the library files
# The module can also look for the following environment variables if paths
# are not given as cmake variable: BLAS_DIR, BLAS_INCDIR, BLAS_LIBDIR
# For MKL case and if no paths are given as hints, we will try to use the MKLROOT
# environment variable
# BLAS_VERBOSE Print some additional information during BLAS libraries detection

### List of vendors (BLA_VENDOR) valid in this module
########## List of vendors (BLA_VENDOR) valid in this module
## Open (for OpenBlas), Eigen (for EigenBlas), Goto, ATLAS PhiPACK,
## CXML, DXML, SunPerf, SCSL, SGIMATH, IBMESSL, IBMESSLMT
## 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
###
# We handle different modes to find the dependency
#
# - Detection if already installed on the system
# - BLAS libraries can be detected from different ways
# Here is the order of precedence:
# 1) we look in cmake variable BLAS_LIBDIR or BLAS_DIR (we guess the libdirs) if defined
# 2) we look in environment variable BLAS_LIBDIR or BLAS_DIR (we guess the libdirs) if defined
# 3) we look in common environnment variables depending on the system (INCLUDE, C_INCLUDE_PATH, CPATH - LIB, DYLD_LIBRARY_PATH, LD_LIBRARY_PATH)
# 4) we look in common system paths depending on the system, see for example paths contained in the following cmake variables:
# - CMAKE_PLATFORM_IMPLICIT_INCLUDE_DIRECTORIES, CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES
# - CMAKE_C_IMPLICIT_INCLUDE_DIRECTORIES, CMAKE_C_IMPLICIT_LINK_DIRECTORIES
