+#
+# 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:
#
-# Usage
-# ^^^^^
+# ``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.
#
-# To use this module, call ``find_package(MPI)``. If you are happy with the
-# auto-detected configuration for your language, then you're done. If
-# not, you have two options:
+# Each of the search steps may be skipped with the following control variables:
#
-# 1. Set ``MPI_<lang>_COMPILER`` to the MPI wrapper (e.g. ``mpicc``) of your
-# choice and reconfigure. FindMPI will attempt to determine all the
-# necessary variables using *that* compiler's compile and link flags.
-# 2. If this fails, or if your MPI implementation does not come with
-# a compiler wrapper, then set both ``MPI_<lang>_LIBRARIES`` and
-# ``MPI_<lang>_INCLUDE_PATH``. You may also set any other variables
-# listed above, but these two are required. This will circumvent
-# autodetection entirely.
+# ``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.
#
-# When configuration is successful, ``MPI_<lang>_COMPILER`` will be set to
-# the compiler wrapper for ``<lang>``, if it was found. ``MPI_<lang>_FOUND``
-# and other variables above will be set if any MPI implementation was
-# found for ``<lang>``, regardless of whether a compiler was found.
+# Additionally, the following control variable is available to change search behavior:
#
-# When using ``MPIEXEC`` to execute MPI applications, you should typically
-# use all of the ``MPIEXEC`` flags as follows:
+# ``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} ${MPIEXEC_NUMPROC_FLAG} ${MPIEXEC_MAX_NUMPROCS}
+# ${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.

+ # For C and C++, we're done here (MSMPI does not ship the MPI-2 C++ bindings) - however, for Fortran

+ # MSMPI ships 2-4 Fortran libraries, each for different Fortran compiler behaviors. The library names
+ # ending with a c are using the cdecl calling convention, whereas those ending with an s are for Fortran
+ # implementations using stdcall. Therefore, the 64-bit MSMPI only ships those ending in 'c', whereas the 32-bit
+ # has both variants available.

+ # passed by the Fortran compiler after all other arguments on the parameter list, if it's an m(ixed),
+ # it's passed immediately after the string address.
+
+ # To summarize:
+ # - 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
+ # - msmpifms: CHARACTER length passed directly after string address and using stdcall calling convention
+ # 32-bit MSMPI ships all four libraries, 64-bit MSMPI ships only the first two.
+
+ # As is, Intel Fortran and PGI Fortran both use the 'ec' variant of the calling convention, whereas
+ # the old Compaq Visual Fortran compiler defaulted to the 'ms' version. It's possible to make Intel Fortran
+ # use the CVF calling convention using /iface:cvf, but we assume - and this is also assumed in FortranCInterface -
+ # this isn't the case. It's also possible to make CVF use the 'ec' variant, using /iface=(cref,nomixed_str_len_arg).
+
+ # Our strategy is now to locate all libraries, but enter msmpifec into the LIB_NAMES array.
