++# - Find HDF5, a library for reading and writing self describing array data.
++#
++# This module invokes the HDF5 wrapper compiler that should be installed
++# alongside HDF5.  Depending upon the HDF5 Configuration, the wrapper compiler
++# is called either h5cc or h5pcc.  If this succeeds, the module will then call
++# the compiler with the -show argument to see what flags are used when compiling
++# an HDF5 client application.
++#
++# The module will optionally accept the COMPONENTS argument.  If no COMPONENTS
++# are specified, then the find module will default to finding only the HDF5 C
++# library.  If one or more COMPONENTS are specified, the module will attempt to
++# find the language bindings for the specified components.  The only valid
++# components are C, CXX, Fortran, HL, and Fortran_HL.  If the COMPONENTS
++# argument is not given, the module will attempt to find only the C bindings.
++#
++# On UNIX systems, this module will read the variable HDF5_USE_STATIC_LIBRARIES
++# to determine whether or not to prefer a static link to a dynamic link for HDF5
++# and all of it's dependencies.  To use this feature, make sure that the
++# HDF5_USE_STATIC_LIBRARIES variable is set before the call to find_package.
++#
++# To provide the module with a hint about where to find your HDF5 installation,
++# you can set the environment variable HDF5_ROOT.  The Find module will then
++# look in this path when searching for HDF5 executables, paths, and libraries.
++#
++# In addition to finding the includes and libraries required to compile an HDF5
++# client application, this module also makes an effort to find tools that come
++# with the HDF5 distribution that may be useful for regression testing.
++#
++# This module will define the following variables:
++#  HDF5_INCLUDE_DIRS - Location of the hdf5 includes
++#  HDF5_INCLUDE_DIR - Location of the hdf5 includes (deprecated)
++#  HDF5_DEFINITIONS - Required compiler definitions for HDF5
++#  HDF5_C_LIBRARIES - Required libraries for the HDF5 C bindings.
++#  HDF5_CXX_LIBRARIES - Required libraries for the HDF5 C++ bindings
++#  HDF5_Fortran_LIBRARIES - Required libraries for the HDF5 Fortran bindings
++#  HDF5_HL_LIBRARIES - Required libraries for the HDF5 high level API
++#  HDF5_Fortran_HL_LIBRARIES - Required libraries for the high level Fortran
++#                              bindings.
++#  HDF5_LIBRARIES - Required libraries for all requested bindings
++#  HDF5_FOUND - true if HDF5 was found on the system
++#  HDF5_LIBRARY_DIRS - the full set of library directories
++#  HDF5_IS_PARALLEL - Whether or not HDF5 was found with parallel IO support
++#  HDF5_C_COMPILER_EXECUTABLE - the path to the HDF5 C wrapper compiler
++#  HDF5_CXX_COMPILER_EXECUTABLE - the path to the HDF5 C++ wrapper compiler
++#  HDF5_Fortran_COMPILER_EXECUTABLE - the path to the HDF5 Fortran wrapper compiler
++#  HDF5_DIFF_EXECUTABLE - the path to the HDF5 dataset comparison tool
