If +# ``Wayland_<component>_FOUND`` is TRUE, the imported target +# ``Wayland::<component>`` will be defined. This module will also attempt to +# determine ``Wayland_*_VERSION`` variables for each imported target, although +# ``Wayland_VERSION`` should normally be sufficient. +# +# In general we recommend using the imported targets, as they are easier to use +# and provide more control.
