# Try to find Wayland on a Unix system
#
-# This will define:
+# This is a component-based find module, which makes use of the COMPONENTS
+# and OPTIONAL_COMPONENTS arguments to find_module. The following components
+# are available:
#
-# Wayland_FOUND - True if Wayland is available
-# Wayland_LIBRARIES - Link these to use Wayland
-# Wayland_INCLUDE_DIRS - Include directory for Wayland
-# Wayland_DEFINITIONS - Compiler flags for using Wayland
-# Wayland_VERSION_STRING - Found Wayland version
+# Client Server Cursor Egl
#
-# In addition the following more fine grained variables will be defined:
+# If no components are specified, this module will act as though all components
+# were passed to OPTIONAL_COMPONENTS.
#
-# Wayland_Client_FOUND Wayland_Client_INCLUDE_DIR Wayland_Client_LIBRARY Wayland_Client_VERSION_STRING
-# Wayland_Server_FOUND Wayland_Server_INCLUDE_DIR Wayland_Server_LIBRARY Wayland_Server_VERSION_STRING
-# Wayland_Cursor_FOUND Wayland_Cursor_INCLUDE_DIR Wayland_Cursor_LIBRARY Wayland_Cursor_VERSION_STRING
-# Wayland_Egl_FOUND Wayland_Egl_INCLUDE_DIR Wayland_Egl_LIBRARY Wayland_Egl_VERSION_STRING
+# This module will define the following variables, independently of the
+# components searched for or found:
#
-# Additionally, the following imported targets will be defined:
+# Wayland_FOUND - True if (the requestion version of) Wayland is available
+# Wayland_VERSION - Found Wayland version
#
-# Wayland::Client
-# Wayland::Server
-# Wayland::Cursor
-# Wayland::Egl
+# For each searched-for components, Wayland_<component>_FOUND will be set to true
+# if the corresponding Wayland library was found, and false otherwise. 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.
