cmake_minimum_required (VERSION 2.8.10)
PROJECT (HDF5 C CXX)

#-----------------------------------------------------------------------------
# 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
#   to ensure that the correct versions configured are used.
#
# HDF5_INSTALL_BIN_DIR, HDF5_INSTALL_LIB_DIR, HDF5_INSTALL_INCLUDE_DIR, HDF5_INSTALL_DATA_DIR :
#   Customize the 'bin', 'lib', 'include', and 'share' installation directories.
#
# HDF5_INSTALL_NO_DEVELOPMENT :
#   Set to true to skip installation of headers and CMake package files.
#
# Consider this example from the ParaView project, it builds its own zlib
# library and tells HDF5 to add it as a dependency - this ensures that
# any project making use of this build of HDF5 will use the correct zlib
#
#   # Tell hdf5 that we are manually overriding certain settings
#   SET(HDF5_EXTERNALLY_CONFIGURED 1)
#   # Avoid duplicating names of installed libraries
#   SET(HDF5_EXTERNAL_LIB_PREFIX "vtk")
#   # Export configuration to this export variable
#   SET(HDF5_EXPORTED_TARGETS "paraview-targets")
#
#   # Setup all necessary overrides for zlib so that HDF5 uses our
#   # internally compiled zlib rather than any other version

#     # We must tell the main HDF5 library that it depends on our zlib
