From 53f17333f830d4f314bbe10ba32889bbcfbc3c46 Mon Sep 17 00:00:00 2001 From: Brad King Date: Mon, 3 Apr 2017 13:19:52 -0400 Subject: CMakeParseImplicitLinkInfo: Ignore ld -lto_library flag The `ld` tool in Xcode 8.3 now has a `-lto_library ` flag. Ignore the flag instead of accidentally parsing it as `-l` with `to_library`.
