-# FindMPI
-# -------
-#
-# Find a Message Passing Interface (MPI) implementation.
-#
-# The Message Passing Interface (MPI) is a library used to write
-# high-performance distributed-memory parallel applications, and is
-# typically deployed on a cluster. MPI is a standard interface (defined
-# by the MPI forum) for which many implementations are available.
-#
-# Variables for using MPI
-# ^^^^^^^^^^^^^^^^^^^^^^^
-#
-# The module exposes the components ``C``, ``CXX``, ``MPICXX`` and ``Fortran``.
-# Each of these controls the various MPI languages to search for.
-# The difference between ``CXX`` and ``MPICXX`` is that ``CXX`` refers to the
-# MPI C API being usable from C++, whereas ``MPICXX`` refers to the MPI-2 C++ API
-# that was removed again in MPI-3.
-#
-# Depending on the enabled components the following variables will be set:
-#
-# ``MPI_FOUND``
-# Variable indicating that MPI settings for all requested languages have been found.
-# If no components are specified, this is true if MPI settings for all enabled languages
-# were detected. Note that the ``MPICXX`` component does not affect this variable.
-# ``MPI_VERSION``
-# Minimal version of MPI detected among the requested languages, or all enabled languages
-# if no components were specified.
-#
-# This module will set the following variables per language in your
-# project, where ``<lang>`` is one of C, CXX, or Fortran:
-#
-# ``MPI_<lang>_FOUND``
-# Variable indicating the MPI settings for ``<lang>`` were found and that
-# simple MPI test programs compile with the provided settings.
-# ``MPI_<lang>_COMPILER``
-# MPI compiler for ``<lang>`` if such a program exists.
-# ``MPI_<lang>_COMPILE_OPTIONS``
-# Compilation options for MPI programs in ``<lang>``, given as a :ref:`;-list <CMake Language Lists>`.
-# ``MPI_<lang>_COMPILE_DEFINITIONS``
-# Compilation definitions for MPI programs in ``<lang>``, given as a :ref:`;-list <CMake Language Lists>`.
-# ``MPI_<lang>_INCLUDE_DIRS``
-# Include path(s) for MPI header.
-# ``MPI_<lang>_LINK_FLAGS``
-# Linker flags for MPI programs.
-# ``MPI_<lang>_LIBRARIES``
-# All libraries to link MPI programs against.
-#
-# Additionally, the following :prop_tgt:`IMPORTED` targets are defined:
-#
-# ``MPI::MPI_<lang>``
-# Target for using MPI from ``<lang>``.
-#
-# The following variables indicating which bindings are present will be defined:
-#
-# ``MPI_MPICXX_FOUND``
-# Variable indicating whether the MPI-2 C++ bindings are present (introduced in MPI-2, removed with MPI-3).
-# ``MPI_Fortran_HAVE_F77_HEADER``
-# True if the Fortran 77 header ``mpif.h`` is available.
-# ``MPI_Fortran_HAVE_F90_MODULE``
-# True if the Fortran 90 module ``mpi`` can be used for accessing MPI (MPI-2 and higher only).
-# ``MPI_Fortran_HAVE_F08_MODULE``
-# True if the Fortran 2008 ``mpi_f08`` is available to MPI programs (MPI-3 and higher only).
-#
-# If possible, the MPI version will be determined by this module. The facilities to detect the MPI version
-# were introduced with MPI-1.2, and therefore cannot be found for older MPI versions.
-#
-# ``MPI_<lang>_VERSION_MAJOR``
-# Major version of MPI implemented for ``<lang>`` by the MPI distribution.
-# ``MPI_<lang>_VERSION_MINOR``
-# Minor version of MPI implemented for ``<lang>`` by the MPI distribution.
-# ``MPI_<lang>_VERSION``
-# MPI version implemented for ``<lang>`` by the MPI distribution.
-#
-# Note that there's no variable for the C bindings being accessible through ``mpi.h``, since the MPI standards
-# always have required this binding to work in both C and C++ code.
-#
-# For running MPI programs, the module sets the following variables
-#
-# ``MPIEXEC_EXECUTABLE``
-# Executable for running MPI programs, if such exists.
-# ``MPIEXEC_NUMPROC_FLAG``
-# Flag to pass to ``mpiexec`` before giving it the number of processors to run on.
-# ``MPIEXEC_MAX_NUMPROCS``
-# Number of MPI processors to utilize. Defaults to the number
-# of processors detected on the host system.
-# ``MPIEXEC_PREFLAGS``
-# Flags to pass to ``mpiexec`` directly before the executable to run.
-# ``MPIEXEC_POSTFLAGS``
-# Flags to pass to ``mpiexec`` after other flags.
-#
-# Variables for locating MPI
-# ^^^^^^^^^^^^^^^^^^^^^^^^^^
-#
-# This module performs a three step search for an MPI implementation:
-#
-# 1. Check if the compiler has MPI support built-in. This is the case if the user passed a
-# compiler wrapper as ``CMAKE_<LANG>_COMPILER`` or if they're on a Cray system.
-# 2. Attempt to find an MPI compiler wrapper and determine the compiler information from it.
-# 3. Try to find an MPI implementation that does not ship such a wrapper by guessing settings.
-# Currently, only Microsoft MPI and MPICH2 on Windows are supported.
-#
-# For controlling the second step, the following variables may be set:
-#
-# ``MPI_<lang>_COMPILER``
-# Search for the specified compiler wrapper and use it.
-# ``MPI_<lang>_COMPILER_FLAGS``
-# Flags to pass to the MPI compiler wrapper during interrogation. Some compiler wrappers
-# support linking debug or tracing libraries if a specific flag is passed and this variable
-# may be used to obtain them.
-# ``MPI_COMPILER_FLAGS``
-# Used to initialize ``MPI_<lang>_COMPILER_FLAGS`` if no language specific flag has been given.
-# Empty by default.
-# ``MPI_EXECUTABLE_SUFFIX``
-# A suffix which is appended to all names that are being looked for. For instance you may set this
-# to ``.mpich`` or ``.openmpi`` to prefer the one or the other on Debian and its derivatives.
-#
-# In order to control the guessing step, the following variable may be set:
-#
-# ``MPI_GUESS_LIBRARY_NAME``
-# Valid values are ``MSMPI`` and ``MPICH2``. If set, only the given library will be searched for.
-# By default, ``MSMPI`` will be preferred over ``MPICH2`` if both are available.
-# This also sets ``MPI_SKIP_COMPILER_WRAPPER`` to ``true``, which may be overridden.
-#
-# Each of the search steps may be skipped with the following control variables:
-#
-# ``MPI_ASSUME_NO_BUILTIN_MPI``
-# If true, the module assumes that the compiler itself does not provide an MPI implementation and
-# skips to step 2.
-# ``MPI_SKIP_COMPILER_WRAPPER``
-# If true, no compiler wrapper will be searched for.
-# ``MPI_SKIP_GUESSING``
-# If true, the guessing step will be skipped.
-#
-# Additionally, the following control variable is available to change search behavior:
-#
-# ``MPI_CXX_SKIP_MPICXX``
-# Add some definitions that will disable the MPI-2 C++ bindings.
-# Currently supported are MPICH, Open MPI, Platform MPI and derivatives thereof,
-# for example MVAPICH or Intel MPI.
-#
-# If the find procedure fails for a variable ``MPI_<lang>_WORKS``, then the settings detected by or passed to
-# the module did not work and even a simple MPI test program failed to compile.
-#
-# If all of these parameters were not sufficient to find the right MPI implementation, a user may
-# disable the entire autodetection process by specifying both a list of libraries in ``MPI_<lang>_LIBRARIES``
-# and a list of include directories in ``MPI_<lang>_ADDITIONAL_INCLUDE_DIRS``.
-# Any other variable may be set in addition to these two. The module will then validate the MPI settings and store the
-# settings in the cache.
-#
-# Cache variables for MPI
-# ^^^^^^^^^^^^^^^^^^^^^^^
-#
-# The variable ``MPI_<lang>_INCLUDE_DIRS`` will be assembled from the following variables.
-# For C and CXX:
-#
-# ``MPI_<lang>_HEADER_DIR``
-# Location of the ``mpi.h`` header on disk.
-#
-# For Fortran:
-#
-# ``MPI_Fortran_F77_HEADER_DIR``
-# Location of the Fortran 77 header ``mpif.h``, if it exists.
-# ``MPI_Fortran_MODULE_DIR``
-# Location of the ``mpi`` or ``mpi_f08`` modules, if available.
-#
-# For all languages the following variables are additionally considered:
-#
-# ``MPI_<lang>_ADDITIONAL_INCLUDE_DIRS``
-# A :ref:`;-list <CMake Language Lists>` of paths needed in addition to the normal include directories.
-# ``MPI_<include_name>_INCLUDE_DIR``
-# Path variables for include folders referred to by ``<include_name>``.
-# ``MPI_<lang>_ADDITIONAL_INCLUDE_VARS``
-# A :ref:`;-list <CMake Language Lists>` of ``<include_name>`` that will be added to the include locations of ``<lang>``.
-#
-# The variable ``MPI_<lang>_LIBRARIES`` will be assembled from the following variables:
-#
-# ``MPI_<lib_name>_LIBRARY``
-# The location of a library called ``<lib_name>`` for use with MPI.
-# ``MPI_<lang>_LIB_NAMES``
-# A :ref:`;-list <CMake Language Lists>` of ``<lib_name>`` that will be added to the include locations of ``<lang>``.
-#
-# Usage of mpiexec
-# ^^^^^^^^^^^^^^^^
-#
-# When using ``MPIEXEC_EXECUTABLE`` to execute MPI applications, you should typically
-# use all of the ``MPIEXEC_EXECUTABLE`` flags as follows:
-#
-# ::
-#
-# ${MPIEXEC_EXECUTABLE} ${MPIEXEC_NUMPROC_FLAG} ${MPIEXEC_MAX_NUMPROCS}
-# ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS
-#
-# where ``EXECUTABLE`` is the MPI program, and ``ARGS`` are the arguments to
-# pass to the MPI program.
-#
-# Advanced variables for using MPI
-# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-#
-# The module can perform some advanced feature detections upon explicit request.
-#
-# **Important notice:** The following checks cannot be performed without *executing* an MPI test program.
-# Consider the special considerations for the behavior of :command:`try_run` during cross compilation.
-# Moreover, running an MPI program can cause additional issues, like a firewall notification on some systems.
-# You should only enable these detections if you absolutely need the information.
-#
-# If the following variables are set to true, the respective search will be performed:
-#
-# ``MPI_DETERMINE_Fortran_CAPABILITIES``
-# Determine for all available Fortran bindings what the values of ``MPI_SUBARRAYS_SUPPORTED`` and
-# ``MPI_ASYNC_PROTECTS_NONBLOCKING`` are and make their values available as ``MPI_Fortran_<binding>_SUBARRAYS``
-# and ``MPI_Fortran_<binding>_ASYNCPROT``, where ``<binding>`` is one of ``F77_HEADER``, ``F90_MODULE`` and
-# ``F08_MODULE``.
-# ``MPI_DETERMINE_LIBRARY_VERSION``
-# For each language, find the output of ``MPI_Get_library_version`` and make it available as ``MPI_<lang>_LIBRARY_VERSION``.
-# This information is usually tied to the runtime component of an MPI implementation and might differ depending on ``<lang>``.
-# Note that the return value is entirely implementation defined. This information might be used to identify
-# the MPI vendor and for example pick the correct one of multiple third party binaries that matches the MPI vendor.
-#
-# Backward Compatibility
-# ^^^^^^^^^^^^^^^^^^^^^^
-#
-# For backward compatibility with older versions of FindMPI, these
-# variables are set, but deprecated:
-#
-# ::
-#
-# MPI_COMPILER MPI_LIBRARY MPI_EXTRA_LIBRARY
-# MPI_COMPILE_FLAGS MPI_INCLUDE_PATH MPI_LINK_FLAGS
-# MPI_LIBRARIES
-#
-# In new projects, please use the ``MPI_<lang>_XXX`` equivalents.
-# Additionally, the following variables are deprecated:
-#
-# ``MPI_<lang>_COMPILE_FLAGS``
-# Use ``MPI_<lang>_COMPILE_OPTIONS`` and ``MPI_<lang>_COMPILE_DEFINITIONS`` instead.
-# ``MPI_<lang>_INCLUDE_PATH``
-# For consumption use ``MPI_<lang>_INCLUDE_DIRS`` and for specifying folders use ``MPI_<lang>_ADDITIONAL_INCLUDE_DIRS`` instead.

- # - msmpifec: CHARACTER length passed after the parameter list and using cdecl calling convention
- # - msmpifmc: CHARACTER length passed directly after string address and using cdecl calling convention
- # - msmpifes: CHARACTER length passed after the parameter list and using stdcall calling convention
