# - Find NetCDF
# Find the native NetCDF includes and library
#
# NETCDF_INCLUDES - where to find netcdf.h, etc
# NETCDF_LIBRARIES - Link these libraries when using NetCDF
# NETCDF_FOUND - True if NetCDF found including required interfaces (see below)
#
# 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
#
# The following are not for general use and are included in
# NETCDF_LIBRARIES if the corresponding option above is set.
#
# NETCDF_LIBRARIES_C - Just the C interface
# NETCDF_LIBRARIES_CXX - C++ interface, if available
# NETCDF_LIBRARIES_F77 - Fortran 77 interface, if available
# NETCDF_LIBRARIES_F90 - Fortran 90 interface, if available

# set (NETCDF_F90 "YES")
