# - 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_LIBRARIES - uncached list of libraries (using full path name) to 
#    link against to use BLAS
#

include(CheckFortranFunctionExists)

macro(Check_Fortran_Libraries LIBRARIES _prefix _name _flags _list)
# This macro checks for the existence of the combination of fortran libraries
# given by _list.  If the combination is found, this macro checks (using the 
# Check_Fortran_Function_Exists macro) whether can link against that library
# combination using the name of a routine given by _name using the linker
# flags given by _flags.  If the combination of libraries is found and passes
# the link test, LIBRARIES is set to the list of complete library paths that
# have been found.  Otherwise, LIBRARIES is set to FALSE.
 
# N.B. _prefix is the prefix applied to the names of all cached variables that
# are generated internally and marked advanced by this macro.
