Our Git commit hooks disallow modification or addition of lines with
trailing whitespace.  Wipe out all remnants of trailing whitespace
everywhere except third-party code.

# - 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
