# To include HDF5 as a sub-project within another project.
# Set HDF5_EXTERNALLY_CONFIGURED to 1 in the parent project and
# supply values for the following variables...
#
# HDF5_EXPORTED_TARGETS :
#   Set this to the name of the targets variable which controls exports
#   If unset (because parent project does not support/use the
#   install (EXPORT target...) syntax), then targets are not configured
#   for export during install.
#
# HDF5_LIB_DEPENDENCIES :
#   If the build of HDF5 libs is being customized, then rules for the
#   dependencies of the HDF5 libs may be 'incomplete', add additional
#   dependencies to this variable so that external projects pick them up

#   to ensure that the correct versions configured are used.

mark_as_advanced (HDF5_LIB_INFIX)
# HDF5_LIB_INFIX :
#   This infix is added to all library names after 'hdf5'.
#   e.g. the infix '_openmpi' results in the library name 'libhdf5_openmpi.so'
#   This name is used in packages on debian based systems.

#   Set to true to skip installation of headers and CMake package files.
#
# Consider this example from the ParaView project, it builds its own zlib
