dnl @synopsis ACX_LAPACK([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
dnl
dnl This macro looks for a library that implements the LAPACK
dnl linear-algebra interface (see http://www.netlib.org/lapack/). On
dnl success, it sets the LAPACK_LIBS output variable to hold the
dnl requisite library linkages.
dnl
dnl To link with LAPACK, you should link with:
dnl
dnl $LAPACK_LIBS $BLAS_LIBS $LIBS $FLIBS
dnl
dnl in that order. BLAS_LIBS is the output variable of the ACX_BLAS
dnl macro, called automatically. FLIBS is the output variable of the
dnl AC_F77_LIBRARY_LDFLAGS macro (called if necessary by ACX_BLAS), and
dnl is sometimes necessary in order to link with F77 libraries. Users
dnl will also need to use AC_F77_DUMMY_MAIN (see the autoconf manual),
dnl for the same reason.
dnl
dnl The user may also use --with-lapack=<lib> in order to use some
dnl specific LAPACK library <lib>. In order to link successfully,
dnl however, be aware that you will probably need to use the same
dnl Fortran compiler (which can be set via the F77 env. var.) as was
dnl used to compile the LAPACK and BLAS libraries.
dnl
dnl ACTION-IF-FOUND is a list of shell commands to run if a LAPACK
dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to
dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the
dnl default action will define HAVE_LAPACK.
