# - Find HDF5 library
# Find the native HDF5 includes and libraries
# This module defines
#  HDF5_INCLUDE_DIRS, where to find hdf5.h, Set when HDF5_INCLUDE_DIR is found.
#  HDF5_LIBRARIES, libraries to link against to use HDF5.
#  HDF5_ROOT_DIR, The base directory to search for HDF5.
#                 This can also be an environment variable.
#  HDF5_FOUND, If false, do not try to use HDF5.
