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 valid components are ``C``, ``CXX``, ``Fortran``, ``HL``. +``HL`` refers to the "high-level" HDF5 functions for C and Fortran. +If the ``COMPONENTS`` argument is not given, the module will +attempt to find only the C bindings. +For example, to use Fortran HDF5 and HDF5-HL functions, do: +``find_package(HDF5 COMPONENTS Fortran HL)``. + +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. + +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. + +Result Variables +^^^^^^^^^^^^^^^^ + +This module will set the following variables in your project: + +``HDF5_FOUND`` + HDF5 was found on the system +``HDF5_VERSION`` + HDF5 library version +``HDF5_INCLUDE_DIRS`` + Location of the HDF5 header files +``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.
