+Subject: [PATCH] Switch to use pkg-config to detect libevent and openssl
+
+Switching to pkg-config fixes a number of problems when detecting the
+libraries. For example the detection of libpthread was failing,
+because libevent_threads was added to LIBS before libevent itself,
+causing the libpthread test to fail due to missing symbols. pkg-config
+is anyway nowadays the preferred way for detecting libraries. It also
+has the benefit of working properly in static library situations.
