# FindQtWaylandScanner
# --------------------
#
# Try to find qtwaylandscanner.
#
# If the qtwaylandscanner executable is not in your PATH, you can provide
# an alternative name or full path location with the ``QtWaylandScanner_EXECUTABLE``
# variable.
#
# This will define the following variables:
#
# ``QtWaylandScanner_FOUND``
#     True if qtwaylandscanner is available
#
# ``QtWaylandScanner_EXECUTABLE``
#     The qtwaylandscanner executable.
#
# If ``QtWaylandScanner_FOUND`` is TRUE, it will also define the following imported
# target:
#
# ``Wayland::QtScanner``
#     The qtwaylandscanner executable.
#
# This module provides the following functions to generate C++ protocol
# implementations:
#
#   - ``ecm_add_qtwayland_client_protocol``
#   - ``ecm_add_qtwayland_server_protocol``
#
# ::
#
#   ecm_add_qtwayland_client_protocol(<source_files_var>
#                                     PROTOCOL <xmlfile>
#                                     BASENAME <basename>
#                                     [PREFIX <prefix>])
#
# Generate C++ wrapper to Wayland client protocol files from ``<xmlfile>``
# XML definition for the ``<basename>`` interface and append those files
# to ``<source_files_var>``.  Pass the ``<prefix>`` argument if the interface
# names don't start with ``qt_`` or ``wl_``.
#
# WaylandScanner is required and will be searched for.
#
# ::
#
#   ecm_add_qtwayland_server_protocol(<source_files_var>
#                                     PROTOCOL <xmlfile>
#                                     BASENAME <basename>
#                                     [PREFIX <prefix>])
#
# Generate C++ wrapper to Wayland server protocol files from ``<xmlfile>``
# XML definition for the ``<basename>`` interface and append those files
# to ``<source_files_var>``.  Pass the ``<prefix>`` argument if the interface
# names don't start with ``qt_`` or ``wl_``.
#
# WaylandScanner is required and will be searched for.
#
# Since 1.4.0.
