+#
+# - 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 mainly taken
+# 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_INCLUDE_DIR - Directories containing the BLAS header files
-# BLAS_DEFINITIONS - Compilation options to use BLAS
-# BLAS_LINKER_FLAGS - Linker flags to use BLAS (excluding -l
+# BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
# and -L).
-# BLAS_LIBRARIES_DIR - Directories containing the BLAS libraries.
-# May be null if BLAS_LIBRARIES contains libraries name using full path.
-# BLAS_LIBRARIES - List of libraries to link against BLAS interface.
-# May be null if the compiler supports auto-link (e.g. VC++).
-# BLAS_USE_FILE - The name of the cmake module to include to compile
-# applications or libraries using BLAS.
+# 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
#
-# This module was modified by CGAL team:
-# - find libraries for a C++ compiler, instead of Fortran
-# - added BLAS_INCLUDE_DIR, BLAS_DEFINITIONS and BLAS_LIBRARIES_DIR
-# - removed BLAS95_LIBRARIES
+# - 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
