This is what Soot currently does, using a default set of entry points.
You can override this default set by calling Scene.v().setEntryPoints()
with a List of SootMethod(s) before the call graph gets built. The
default entry points are listed in
soot.jimple.toolkits.callgraph.EntryPoints.

To build a call graph which includes all methods of all application
classes, use the switch: -p cg all-reachable.
