+#
+# This will define the following variables:
+#
+# ``PipeWire_FOUND``
+#     True if (the requested version of) PipeWire is available
+# ``PipeWire_VERSION``
+#     The version of PipeWire
+# ``PipeWire_LIBRARIES``
+#     This can be passed to target_link_libraries() instead of the ``PipeWire::PipeWire``
+#     target
+# ``PipeWire_INCLUDE_DIRS``
+#     This should be passed to target_include_directories() if the target is not
+#     used for linking
+# ``PipeWire_DEFINITIONS``
+#     This should be passed to target_compile_options() if the target is not
+#     used for linking
+#
+# If ``PipeWire_FOUND`` is TRUE, it will also define the following imported target:
+#
+# ``PipeWire::PipeWire``
+#     The PipeWire library
+#
+# In general we recommend using the imported target, as it is easier to use.
+# Bear in mind, however, that if the target is in the link interface of an
+# exported library, it must be made available by the package config file.
