Reinstalling dependencies with provided script would delete dependencies of other BLAST codes

[n01r]

Following the instructions right above the Compilation section in our docs recommends to use the script $HOME/src/warpx/Tools/machines/perlmutter-nersc/install_gpu_dependencies.sh.

On Perlmutter, the software dependency directory for a given project looks like this

(warpx) mgarten@perlmutter:login20:~/src/warpx> ls /global/cfs/cdirs/m3239/mgarten/sw/perlmutter/gpu/venvs/
impactx/ warpx/   

The script removes the old dependencies however and this would also break the ImpactX workflow by removing its installed dependencies

# Remove old dependencies #####################################################
#
SW_DIR="${CFS}/${proj%_g}/${USER}/sw/perlmutter/gpu"
rm -rf ${SW_DIR}
mkdir -p ${SW_DIR}

Is it better to unify the dependencies for the BLAST codes or to separate them by code?
Maybe the latter?

We could instead do

SW_DIR="${CFS}/${proj%_g}/${USER}/sw/perlmutter/warpx/gpu"

or

SW_DIR="${CFS}/${proj%_g}/${USER}/sw/perlmutter/gpu/warpx/"
