Syntax from src dir: make lib-libname args="-m machine -e suffix"
Syntax from lib dir: python Install.py -m machine -e suffix
libname = name of lib dir (e.g. atc, colvars, h5md, meam, poems, etc)
specify -m and optionally -e, order does not matter
-m = peform a clean followed by "make -f Makefile.machine"
machine = suffix of a lib/Makefile.* file
-e = set EXTRAMAKE variable in Makefile.machine to Makefile.lammps.suffix
does not alter existing Makefile.machine
Examplesx:
make lib-colvars args="-m g++" # build COLVARS lib with GNU g++ compiler
make lib-meam args="-m ifort" # build MEAM lib with Intel ifort compiler
