			# - Find NetCDF
			# Find the native NetCDF includes and library
			#
			# NETCDF_INCLUDE_DIR - user modifiable choice of where netcdf headers are
			# NETCDF_LIBRARY - user modifiable choice of where netcdf libraries are
			#
			# Your package can require certain interfaces to be FOUND by setting these
			#
			# NETCDF_CXX - require the C++ interface and link the C++ library
			# NETCDF_F77 - require the F77 interface and link the fortran library
			# NETCDF_F90 - require the F90 interface and link the fortran library
			#
			# Or equivalently by calling FindNetCDF with a COMPONENTS argument containing one or
			# more of "CXX;F77;F90".
			#
			# When interfaces are requested the user has access to interface specific hints:
			#
			# NETCDF_${LANG}_INCLUDE_DIR - where to search for interface header files
			# NETCDF_${LANG}_LIBRARY - where to search for interface libraries
			#
			# This module returns these variables for the rest of the project to use.
			#
			# NETCDF_FOUND - True if NetCDF found including required interfaces (see below)
			# NETCDF_LIBRARIES - All netcdf related libraries.
			# NETCDF_INCLUDE_DIRS - All directories to include.
			# NETCDF_HAS_INTERFACES - Whether requested interfaces were found or not.
			# NETCDF_${LANG}_INCLUDE_DIRS/NETCDF_${LANG}_LIBRARIES - C/C++/F70/F90 only interface
			#
			# Normal usage would be:
			# set (NETCDF_F90 "YES")
			# find_package (NetCDF REQUIRED)
			# target_link_libraries (uses_everthing ${NETCDF_LIBRARIES})
			# target_link_libraries (only_uses_f90 ${NETCDF_F90_LIBRARIES})
