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(<target>
PROTOCOL <xmlfile>
BASENAME <basename>
[PREFIX <prefix>])
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>`` or ``<target>``. 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(<target>
PROTOCOL <xmlfile>
BASENAME <basename>
[PREFIX <prefix>])
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>`` or ``<target>``. 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.
