+Subject: [PATCH] Adjust .pc file not to expose used crypto library
+References: https://github.com/cisco/libsrtp/pull/537
+References: https://bugzilla.suse.com/show_bug.cgi?id=1185931
+
+srtp headers are not directly including openssl headers. The srtp (shared)
+library already has links to libcrypto and so -lcrypto is at best only needed
+for static linking, but that must go into a the field called "private".
