# Based on the MSTK NetCDF Find Module which is from Amanzi open
# source code https://software.lanl.gov/ascem/trac #

# Control the search through NetCDF_DIR or setting environment variable
# NetCDF_ROOT to the NetCDF installation prefix.
#
# This module does not search default paths!
#
# Following variables are set:
# NetCDF_FOUND (BOOL) Flag indicating if NetCDF was found
# NetCDF_INCLUDE_DIR (PATH) Path to the NetCDF include file
# NetCDF_INCLUDE_DIRS (LIST) List of all required include files
# NetCDF_LIBRARY_DIR (PATH) Path to the NetCDF library
# NetCDF_LIBRARY (FILE) NetCDF library
# NetCDF_LIBRARIES (LIST) List of all required NetCDF libraries
#
# Additional variables set
# NetCDF_C_LIBRARY (FILE) NetCDF C library
# NetCDF_CXX_LIBRARY (FILE) NetCDF C++ library
