# FindHDF5
# --------
#
# 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.
#
# 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.
#
# Both the serial and parallel HDF5 wrappers are considered and the first
# directory to contain either one will be used. In the event that both appear
# in the same directory the serial version is preferentially selected. This
# behavior can be reversed by setting the variable HDF5_PREFER_PARALLEL to
# true.
#
# 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_FOUND - true if HDF5 was found on the system
# HDF5_VERSION - HDF5 version in format Major.Minor.Release
# 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_LIBRARIES - Required libraries for all requested bindings
# HDF5_HL_LIBRARIES - Required libraries for the HDF5 high level API for all
# bindings, if the HL component is enabled
#
# Available components are: C CXX Fortran and HL. For each enabled language
# binding, a corresponding HDF5_${LANG}_LIBRARIES variable, and potentially
# HDF5_${LANG}_DEFINITIONS, will be defined.
# If the HL component is enabled, then an HDF5_${LANG}_HL_LIBRARIES will
# also be defined. With all components enabled, the following variables will be defined:
#
# ::
#
# HDF5_C_DEFINITIONS -- Required compiler definitions for HDF5 C bindings
# HDF5_CXX_DEFINITIONS -- Required compiler definitions for HDF5 C++ bindings
# HDF5_Fortran_DEFINITIONS -- Required compiler definitions for HDF5 Fortran bindings
# HDF5_C_INCLUDE_DIRS -- Required include directories for HDF5 C bindings
# HDF5_CXX_INCLUDE_DIRS -- Required include directories for HDF5 C++ bindings
# HDF5_Fortran_INCLUDE_DIRS -- Required include directories for HDF5 Fortran bindings
# 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_C_HL_LIBRARIES - Required libraries for the high level C bindings
# HDF5_CXX_HL_LIBRARIES - Required libraries for the high level C++ bindings
# HDF5_Fortran_HL_LIBRARIES - Required libraries for the high level Fortran
# bindings.
#
# 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_C_COMPILER_EXECUTABLE_NO_INTERROGATE - path to the primary C compiler
# which is also the HDF5 wrapper
# HDF5_CXX_COMPILER_EXECUTABLE_NO_INTERROGATE - path to the primary C++
# compiler which is also
# the HDF5 wrapper
# HDF5_Fortran_COMPILER_EXECUTABLE_NO_INTERROGATE - path to the primary
# Fortran compiler which
# is also the HDF5 wrapper
# HDF5_DIFF_EXECUTABLE - the path to the HDF5 dataset comparison tool
#
# The following variable can be set to guide the search for HDF5 libraries and includes:
#
# ``HDF5_ROOT``
# Specify the path to the HDF5 installation to use.
#
# ``HDF5_FIND_DEBUG``
# Set to a true value to get some extra debugging output.
#
# ``HDF5_NO_FIND_PACKAGE_CONFIG_FILE``
# Set to a true value to skip trying to find ``hdf5-config.cmake``.
# This module is maintained by Will Dicharry <wdicharry@stellarscience.com>.
