# 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.
|
|
#
|
|
# 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.
|
|
#
|
|
# 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_${LANG}_LIBRARIES variable will be defined.
|
|
# If the HL component is enabled, then an HDF5_${LANG}_HL_LIBRARIES will
|
|
# also be defined. With all components enabled, the following variables will be defined:
|
|
#
|
|
# ::
|
|
#
|
|
# HDF5_C_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
|
|

# HDF5_ROOT
