#-----------------------------------------------------------------------------
# Instructions for use : Normal Build
#
# For standard build of HDF5 libraries,tests and tools.
# Run cmake using the HDF5 source tree to generate a build tree.
# Enable/Disable options according to requirements and
# set CMAKE_INSTALL_PREFIX to the required install path.
# Make install can be used to install all components for system-wide use.

# Instructions for use : Sub-Project Build
#
# 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
#
# HDF5_EXTERNAL_LIB_PREFIX :
#   If the parent project needs to install hdf libraries, but avoid
#   name conflicts with system versions, then a prefix may be added
