# This cmake configuration script builds simple_glide, and if you enable it below, 
# and cism_driver on a Mac using the Gnu compiler suite.  
# This build is serial.  See the mac-gnu directory for a parallel build.
# Trilinos is not used.

# This script should be run from the builds/mac-gnu subdirectory
# of the main seacism repository (reflected in the two instances
# of "../.." below).

# 

# BUILD OPTIONS:
# The call to cmake below include several input ON/OFF switch parameters, to
# provide a simple way to select different build options.  These are:
# CISM_SERIAL_MODE -- OFF by default, set to ON here for a serial build.
# CISM_MPI_MODE -- ON by default, set to OFF here for a serial build.
# CISM_USE_TRILINOS -- Set OFF below to exclude Trilinos from the build.
# CISM_BUILD_SIMPLE_GLIDE -- ON by default, set to OFF to not build simple_glide
# CISM_BUILD_SIMPLE_BISICLES -- OFF by default, set to ON to build simple_bisicles
#      Setting NO_TRILINOS to ON will generate a much smaller executable for this build.
# CISM_BUILD_EXTRA_EXECUTABLES -- OFF by default, set to ON to build eis_glide and others
# CISM_USE_GPTL_INSTRUMENTATION -- OFF by default, set to ON to use GPTL instrumentation

# Serial Build Notes:  Setting CISM_USE_TRILINOS=OFF, CISM_MPI_MODE=OFF, CISM_SERIAL_MODE=ON will
# configure for a serial build.  (Note that the openmpi compilers will be used if specified, but act as
# pass-throughs to the underlying serial compilers in this case.  If MPI is not installed,
# set the serial compilers directly.)

# You may need to manually set the NETCDF_PATH variable below to point to your NetCDF installation.  
# If you have NetCDF installed with MacPorts, you can use that by setting it to "/opt/local" 
# (assuming default MacPorts installation location).

# NOTE: There is currently an incompatibility between simple_bisicles and GPTL.  If
# the CISM_BUILD_SIMPLE_BISICLES is ON, the GPTL instrumentation is turned OFF.
