Syntax from src dir: make lib-scafacos args="-b"
or: make lib-scafacos args="-p /usr/local/scafacos"
Syntax from lib dir: python Install.py -b
or: python Install.py -p /usr/local/scafacos
specify zero or more options, order does not matter
-b = download and build the Scafacos library
-p = specify folder of existing Scafacos installation
always creates includelink, liblink to Scafacos dirs
Example:
make lib-scafacos args="-b" # download/build in lib/scafacos/scafacos
make lib-scafacos args="-p $HOME/scafacos" # use existing Scafacos installation in $HOME
