From 4feaf9b61f93e4043eca26b4ec9f9f68d0cf5e68 Mon Sep 17 00:00:00 2001
From: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com>
Date: Wed, 6 Mar 2019 01:08:43 +0300
Subject: [PATCH 1/4] ima-evm-utils: link to libcrypto instead of OpenSSL
There is no need to link to full libssl. evmctl uses functions from
libcrypto, so let's link only against that library.
