# Try to find Wayland on a Unix system
#
# This will define:
#
#   WAYLAND_FOUND       - True if Wayland is found
#   WAYLAND_LIBRARIES   - Link these to use Wayland
#   WAYLAND_INCLUDE_DIR - Include directory for Wayland
#   WAYLAND_DEFINITIONS - Compiler flags for using Wayland
#
# In addition the following more fine grained variables will be defined:
#
#   WAYLAND_CLIENT_FOUND  WAYLAND_CLIENT_INCLUDE_DIR  WAYLAND_CLIENT_LIBRARIES
#   WAYLAND_SERVER_FOUND  WAYLAND_SERVER_INCLUDE_DIR  WAYLAND_SERVER_LIBRARIES
#   WAYLAND_EGL_FOUND     WAYLAND_EGL_INCLUDE_DIR     WAYLAND_EGL_LIBRARIES
