Linking to a dynamic library would become a matter of using the correct compiler version and dependencies versions, and linking to multiple dynamic libraries at the same time could be impossible due to conflicting requirements.\n\nps: I suggest you to use the native quote feature instead of `>`, that way the quoted people will see a notification.",
