From b860de9e207d8fe2ea37dad28fdd014493d87703 Mon Sep 17 00:00:00 2001 From: Fabrice Fontaine Date: Tue, 27 Dec 2022 16:29:16 +0100 Subject: [PATCH] build: Fix CMake to use pkg-config openssl when possible (#2290) In order to take into account the libraries used by openssl when building statically, using pkg-config is recommended. This patch therefore improves the CMakeLists.txt to use pkg-config to detect openssl when pkg-config is available. This will avoid static build failure when openssl needs to link with -latomic.
