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.
