# Try to find Wayland on a Unix system
#
# This will define:
#
# 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
#
# In addition the following more fine grained variables will be defined:
#
# 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_Egl_FOUND Wayland_Egl_INCLUDE_DIR Wayland_Egl_LIBRARY Wayland_Egl_VERSION_STRING
#
# Additionally, the following imported targets will be defined:
#
# Wayland::Client
# Wayland::Server
# Wayland::Cursor
# Wayland::Egl
