On success, it sets the +# CBLAS_LIBS output variable to hold the requisite library linkages. +# +# To link with BLAS, you should link with: +# +# $CBLAS_LIBS $LIBS +# +# 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 CBLAS +# 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 CBLAS 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_CBLAS. +# +# This macro requires autoconf 2.50 or later. +# +# LAST MODIFICATION +# +# 2008-04-12 +# +# COPYLEFT +# +# Copyright (c) 2008 Steven G.
