# Find BLAS library
#
# This module finds an installed library that implements the BLAS
# linear-algebra interface (see http://www.netlib.org/blas/).
# The list of libraries searched for is mainly 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
# and -L).
# BLAS_LIBRARY_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.
#
# This module was modified by CGAL team:
# - find BLAS library shipped with TAUCS
# - find libraries for a C++ compiler, instead of Fortran
# - added BLAS_INCLUDE_DIR, BLAS_DEFINITIONS and BLAS_LIBRARY_DIR
# - removed BLAS95_LIBRARIES
#
# TODO (CGAL):
# - find CBLAS (http://www.netlib.org/cblas) on Unix?
