# SYNOPSIS
#
# AX_PROG_CC_MPI([MPI-WANTED-TEST[, ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]]])
#
# DESCRIPTION
#
# This macro tries to find out how to compile C programs that use MPI
# (Message Passing Interface), a standard API for parallel process
# communication (see http://www-unix.mcs.anl.gov/mpi/). The macro has to
# be used instead of the standard macro AC_PROG_CC and will replace the
# standard variable CC with the found compiler.
#
# MPI-WANTED-TEST is used to test whether MPI is actually wanted by the
# user. If MPI-WANTED_TEST is omitted or if it succeeds, the macro will
# try to find out how to use MPI, if it fails, the macro will call
# AC_PROG_CC to find a standard C compiler instead.
#
# When MPI is found, ACTION-IF-FOUND will be executed, if MPI is not found
# (or MPI-WANTED-TEST fails) ACTION-IF-NOT-FOUND is executed. If
# ACTION-IF-FOUND is not set, the macro will define HAVE_MPI.
#
# The following example demonstrates usage of the macro:
#
# # If --with-mpi=auto is used, try to find MPI, but use standard C compiler if it is not found.
# # If --with-mpi=yes is used, try to find MPI and fail if it isn't found.
# # If --with-mpi=no is used, use a standard C compiler instead.
# AC_ARG_WITH(mpi, [AS_HELP_STRING([--with-mpi],
# [compile with MPI (parallelization) support. If none is found,
# MPI is not used. Default: auto])
# ],,[with_mpi=auto])
# #
# AX_PROG_CC_MPI([test x"$with_mpi" != xno],[use_mpi=yes],[
# use_mpi=no
# if test x"$with_mpi" = xyes; then
# AC_MSG_FAILURE([MPI compiler requested, but couldn't use MPI.])
# else
# AC_MSG_WARN([No MPI compiler found, won't use MPI.])
# fi

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is '.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.
