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.
