From 0dd439141da0fc1a7938ee06f7be3924c73ba716 Mon Sep 17 00:00:00 2001 From: Daniel Engberg Date: Tue, 5 Sep 2017 19:31:10 +0200 Subject: [PATCH] package/libs/zlib: Add option for O3 optimization Add option to use O3 optimization as not all devices have space constraints. This option is default using GCC in upstream but isn't in the CMake makefile for some reason.
