Syntax from src dir: make lib-voronoi args="-v version -h hpath hdir -g -b -l"
Syntax from lib dir: python Install.py -v version -h hpath hdir -g -b -l
specify one or more options, order does not matter
-v = version of Voro++ to download and build
default version = voro++-0.4.6 (current as of Jan 2015)
-h = set home dir of Voro++ to be hpath/hdir
hpath can be full path, contain '~' or '.' chars
default hpath = . = lib/voronoi
default hdir = voro++-0.4.6 = what tarball unpacks to
-g = grab (download) tarball from math.lbl.gov/voro++ website
unpack it to hpath/hdir
hpath must already exist
if hdir already exists, it will be deleted before unpack
-b = build Voro++ library in its src dir
-l = create 2 softlinks (includelink,liblink) in lib/voronoi to Voro++ src dir
Example:
make lib-voronoi args="-g -b -l" # download/build in lib/voronoi/voro++-0.4.6
