From e778668fe92b8c60e0537ee48f79d5af6c1a2f1e Mon Sep 17 00:00:00 2001 From: Dan Sinclair Date: Wed, 29 Mar 2017 15:18:41 -0400 Subject: Move xfa/fxbarcode fxbarcode/ Nothing in fxbarcode/ depends on XFA code. This CL moves xfa/fxbarcode to be fxbarcode/ and creates a static_library for fxbarcode which is depend on by the xfa library.
