#-----------------------------------------------------------------------
# This Makefile is for building cprnc on AIX, Compaq, Linux (with pgf90,
# lf95, ifort, or gfortran compilers), IRIX or SUN platforms.
#
# These macros can be changed by setting environment variables:
#
# Set the path to netcdf:
# 
# gmake NETCDF=pathToNetcdf
#
# This sets LIB_NETCDF=$NETCDF/lib and INC_NETCDF=$NETCDF/include
#
# LIB_NETCDF --- Library directory location of netcdf.
# INC_NETCDF --- Include directory location of netcdf.  This directory needs to contain
#                the NetCDF .mod files, i.e., netcdf.mod and typesizes.mod.
#
# If the include and library files don't have a common root directory then set them
# independently in the commandline:
#
# gmake LIB_NETCDF=pathToLIBFiles INC_NETCDF=pathToINCFiles
#
# You also can set the environment variables:
#
# USER_FC ------ User defined Fortran compiler (for Linux can be pgf90, lf95, ifort, gfortran)
# EXEDIR ------- Directory to build executable in. (Defaults to .)
# VPATH -------- GNU make path. (Defaults to current directory)
