Syntax from src dir: make lib-smd args="-h hpath hdir -g -l"
Syntax from lib dir: python Install.py -h hpath hdir -g -l
specify one or more options, order does not matter
-h = set home dir of Eigen to be hpath/hdir
hpath can be full path, contain '~' or '.' chars
default hpath = . = lib/smd
default hdir = "ee" = what tarball unpacks to (eigen-eigen-*)
-g = grab (download) tarball from http://eigen.tuxfamily.org website
unpack it to hpath/hdir
hpath must already exist
if hdir already exists, it will be deleted before unpack
-l = create softlink (includelink) in lib/smd to Eigen src dir
Example:
make lib-smd args="-g -l" # download/build in default lib/smd/eigen-eigen-*
