+# Adds a library target for a Quassel module.
+#
+# It expects the (CamelCased) module name as a parameter, and derives various
+# strings from it. For example, quassel_add_module(Client) produces
+# - a library target named quassel_client with output name (lib)quassel-client(.so)
+# - an alias target named Quassel::Client in global scope
+#
+# The function exports the TARGET variable which can be used in the current scope
+# for setting source files, properties, link dependencies and so on.
+# To refer to the target outside of the current scope, e.g. for linking, use
+# the alias name.
