+Subject: [PATCH] src/ssl/openssl: add libressl compatibility
+
+Similar to https://github.com/FreeRDP/FreeRDP/issues/5049
+libressl has `#define OPENSSL_VERSION_NUMBER ` defined the same as
+openssl 1.1.x which results in SSL_CTX_set_security_level() getting used.
+
+This patch prevents SSL_CTX_set_security_level() from being used with
+libressl.
