Description: Remove the FindMPI distributed by this package
 since it doesn't find the proper include paths. The system cmake 
 provided version is better at this.

-# - 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. All of them have somewhat different include paths,
-# libraries to link against, etc., and this module tries to smooth
-# out those differences.
-#
-# === Variables ===
-#
-# This module will set the following variables per language in your project,
-# where <lang> is one of C, CXX, or Fortran:
-#   MPI_<lang>_FOUND           TRUE if FindMPI found MPI flags for <lang>
-#   MPI_<lang>_COMPILER        MPI Compiler wrapper for <lang>
-#   MPI_<lang>_COMPILE_FLAGS   Compilation flags for MPI programs
-#   MPI_<lang>_INCLUDE_PATH    Include path(s) for MPI header
-#   MPI_<lang>_LINK_FLAGS      Linking flags for MPI programs
-#   MPI_<lang>_LIBRARIES       All libraries to link MPI programs against
-# Additionally, FindMPI sets the following variables for running MPI
-# programs from the command line:
-#   MPIEXEC                    Executable for running MPI programs
-#   MPIEXEC_NUMPROC_FLAG       Flag to pass to MPIEXEC before giving
-#                              it the number of processors to run on
-#   MPIEXEC_PREFLAGS           Flags to pass to MPIEXEC directly
-#                              before the executable to run.
-#   MPIEXEC_POSTFLAGS          Flags to pass to MPIEXEC after other flags
-# === Usage ===
-#
-# To use this module, simply call FindMPI from a CMakeLists.txt file, or
-# run find_package(MPI), then run CMake.  If you are happy with the auto-
-# detected configuration for your language, then you're done.  If not, you
-# have two options:
-#   1. Set MPI_<lang>_COMPILER to the MPI wrapper (mpicc, etc.) 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.
-# 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.
-#
-# When using MPIEXEC to execute MPI applications, you should typically use
-# all of the MPIEXEC flags as follows:
-#   ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS
-#     ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS
-# where PROCS is the number of processors on which to execute the program,
-# EXECUTABLE is the MPI program, and ARGS are the arguments to pass to the
-# MPI program.
-#
-# === Backward Compatibility ===
-#
-# For backward compatibility with older versions of FindMPI, these
-# variables are set, but deprecated:
-#   MPI_FOUND           MPI_COMPILER        MPI_LIBRARY
-#   MPI_COMPILE_FLAGS   MPI_INCLUDE_PATH    MPI_EXTRA_LIBRARY
-#   MPI_LINK_FLAGS      MPI_LIBRARIES
-# In new projects, please use the MPI_<lang>_XXX equivalents.

-# This part detects MPI compilers, attempting to wade through the mess of compiler names in
-# a sensible way.
-#
-# The compilers are detected in this order:
-#
-# 1. Try to find the most generic available MPI compiler, as this is usually set up by
-#    cluster admins.  e.g., if plain old mpicc is available, we'll use it and assume it's
-#    the right compiler.
-#
-# 2. If a generic mpicc is NOT found, then we attempt to find one that matches
-#    CMAKE_<lang>_COMPILER_ID. e.g. if you are using XL compilers, we'll try to find mpixlc
-#    and company, but not mpiicc.  This hopefully prevents toolchain mismatches.
-#
-# If you want to force a particular MPI compiler other than what we autodetect (e.g. if you
-# want to compile regular stuff with GNU and parallel stuff with Intel), you can always set
-# your favorite MPI_<lang>_COMPILER explicitly and this stuff will be ignored.
-#
-
-# Start out with the generic MPI compiler names, as these are most commonly used.
