AUTORCC
-------
Should the target be processed with autorcc (for Qt projects).
:prop_tgt:`AUTORCC` is a boolean specifying whether CMake will handle
the Qt ``rcc`` code generator automatically, i.e. without having to use
the :module:`QT4_ADD_RESOURCES() <FindQt4>` or ``QT5_ADD_RESOURCES()``
macro. Currently Qt4 and Qt5 are supported.
When this property is ``ON``, CMake will handle ``.qrc`` files added
as target sources at build time and invoke ``rcc`` accordingly.
This property is initialized by the value of the :variable:`CMAKE_AUTORCC`
variable if it is set when a target is created.
By default :prop_tgt:`AUTORCC` is processed inside a
:command:`custom command <add_custom_command>`.
If the ``.qrc`` file is :prop_sf:`GENERATED` though, a
:command:`custom target <add_custom_target>` is used instead.
Additional command line options for rcc can be set via the
:prop_sf:`AUTORCC_OPTIONS` source file property on the ``.qrc`` file.
The ``rcc`` executable will be detected automatically, but can be forced to
a certain binary using the :prop_tgt:`AUTORCC_EXECUTABLE` property.
The global property :prop_gbl:`AUTOGEN_TARGETS_FOLDER` can be used to group
the autorcc targets together in an IDE, e.g. in MSVS.
The global property :prop_gbl:`AUTOGEN_SOURCE_GROUP` can be used to group
files generated by :prop_tgt:`AUTORCC` together in an IDE, e.g. in MSVS.
When there are multiple ``.qrc`` files with the same name, CMake will
generate unspecified unique names for ``rcc``. Therefore if
``Q_INIT_RESOURCE()`` or ``Q_CLEANUP_RESOURCE()`` need to be used the
``.qrc`` file name must be unique.
Source files can be excluded from :prop_tgt:`AUTORCC` processing by
enabling :prop_sf:`SKIP_AUTORCC` or the broader :prop_sf:`SKIP_AUTOGEN`.
A global ``autorcc`` target that depends on all :prop_tgt:`AUTORCC` targets
in the project can be generated by enabling
:variable:`CMAKE_GLOBAL_AUTORCC_TARGET`.
See the :manual:`cmake-qt(7)` manual for more information on using CMake
with Qt.
