# This cmake configuration script builds cism_driver on a Mac using the Gnu compiler suite.
# If Trilinos is used, it relies on a build of Trilinos located in $CISM_TRILINOS_DIR (set below).
# If BISICLES is used, it relies on a build of BISICLES located in $BISICLES_INTERFACE_DIR (set below).

# BUILD OPTIONS:
# The call to cmake below includes several input ON/OFF switch parameters, to
# provide a simple way to select different build options.  These are:
# CISM_BUILD_CISM_DRIVER -- ON by default, set to OFF to only build the CISM libraries.
# CISM_ENABLE_BISICLES -- OFF by default, set to ON to build a BISICLES-capable cism_driver.
# CISM_ENABLE_FELIX -- OFF by default, set to ON to build a FELIX-capable cism_driver.
# CISM_USE_TRILINOS -- OFF by default, set to on for builds with Trilinos.
# CISM_MPI_MODE -- ON by default, only set to OFF for serial builds.
# CISM_SERIAL_MODE -- OFF by default, set to ON for serial builds.
# CISM_USE_GPTL_INSTRUMENTATION -- ON by default, set to OFF to not use GPTL instrumentation.
# CISM_COUPLED -- OFF by default, set to ON to build with CESM.

# After this executes, do:
#   make -j 8

# Set path to top cism directory
# Note, this is an easy way to build out of source.
# In directory you want to build in, run:
#   $ source $CISM/builds/linux-gnu-cism/linux-gnu-cism-cmake $CISM
# where $CISM is the path to the top level cism directory.
