Syntax from src dir: make lib-kim args="-v version -b -a kim-name"
Syntax from lib dir: python Install.py -v version -b -a kim-name

specify one or more options, order does not matter

  -v = version of KIM API library to use
       default = kim-api-v1.8.2 (current as of June 2017)
  -b = download and build KIM API library with example Models
  -a = add single KIM model or model driver with kim-name
       to existing KIM API lib (see example below).
       If kim-name = everything, then rebuild KIM API library with
       all available OpenKIM Models (this implies -b).
  -vv = be more verbose about what is happening while the script runs

Examples:

make lib-kim args="-b"   # install KIM API lib with only example models
make lib-kim args="-b -a Glue_Ercolessi_Adams_Al__MO_324507536345_001"  # Ditto plus one model
make lib-kim args="-b -a everything"   # install KIM API lib with all models
make lib-kim args="-a EAM_Dynamo_Ackland_W__MO_141627196590_002"   # add one model or model driver

See the list of KIM model drivers here:
https://openkim.org/kim-items/model-drivers/alphabetical

See the list of all KIM models here:
https://openkim.org/kim-items/models/by-model-drivers

See the list of example KIM models included by default here:
