On success, it sets the -# BLAS_LIBS output variable to hold the requisite library linkages. -# -# To link with BLAS, you should link with: -# -# $BLAS_LIBS $LIBS $FLIBS -# -# in that order. FLIBS is the output variable of the -# AC_F77_LIBRARY_LDFLAGS macro (called if necessary by AX_BLAS), and is -# sometimes necessary in order to link with F77 libraries. Users will also -# need to use AC_F77_DUMMY_MAIN (see the autoconf manual), for the same -# reason. -# -# Many libraries are searched for, from ATLAS to CXML to ESSL. The user -# may also use --with-blas=<lib> in order to use some specific BLAS -# library <lib>. In order to link successfully, however, be aware that you -# will probably need to use the same Fortran compiler (which can be set -# via the F77 env. var.) as was used to compile the BLAS library. -# -# ACTION-IF-FOUND is a list of shell commands to run if a BLAS library is -# found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it is -# not found. If ACTION-IF-FOUND is not specified, the default action will -# define HAVE_BLAS. -# -# LICENSE -# -# Copyright (c) 2008 Steven G.
