Subject: [PATCH] Several further changes to use the CESM driver:  - compile
 the corresponding MOM6 cap (this is simply a module wrapper around the real
 cap).  - add options to turn on/off the different components (MOM6, WW3 and
 CICE6).  - do not compile the data components when the corresponding model
 component is used.  - set the *_PRESENT compile definitions for the CESM
 driver.
