Compiling ARC4 with CASIM

[leifdenby]

From the met office MONC wiki (https://code.metoffice.gov.uk/trac/monc/wiki/MoncDoc/RunningWithCasim):

Running MONC with CASIM

Initially, the build system won't include the CASIM (Cloud and AeroSol Interacting Microphysics) scheme. To build with CASIM, you must also include the CASIM.cfg in the fcm make step, e.g.

fcm make -f fcm-make/monc_meto.cfg -f fcm-make/casim.cfg

I can do this by running these commands from the monc main directory on install:

mkdir -p $HOME/.metomi/fcm
 sed "s|= |= ${PWD}/fcm-make|" fcm-make/keyword.cfg >> $HOME/.metomi/fcm/keyword.cfg 

This imports the MOSRS paths for casim and socrates, allowing them to be downloaded at build time.
The config files, such as fcm-make/casim.cfg and fcm-make/casim_socrates.cfg have fields to allow the revision number of each package to be specified.

Using this, the above fcm-make command will work. I am running a test now to see if the bomex_casim.mcf file will run with this setup.
