From 8e6441bd11662afd5622df0faceb3c3fa85a64d4 Mon Sep 17 00:00:00 2001 From: Hung-Te Lin Date: Mon, 29 Apr 2019 23:23:25 +0800 Subject: futility: update: Fix build breakage In old factory branch the compiler, dependency libraries and default CFLAGS settings were different so we have to hack for FTW. Also static build (futility_s) needs +static-libs to openssl so let's disable that. Also add libzip to tests.
