# AUTORCC

Should the target be processed with autorcc (for Qt projects).

`AUTORCC` is a boolean specifying whether CMake will handle the Qt `rcc` code generator automatically, i.e. without having to use the `QT4_ADD_RESOURCES()` 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 `CMAKE_AUTORCC` variable if it is set when a target is created.

By default `AUTORCC` is processed inside a `custom command`. If the `.qrc` file is `GENERATED` though, a `custom target` is used instead.

Additional command line options for rcc can be set via the `AUTORCC_OPTIONS` source file property on the `.qrc` file.

The global property `AUTOGEN_TARGETS_FOLDER` can be used to group the autorcc targets together in an IDE, e.g. in MSVS.

The global property `AUTOGEN_SOURCE_GROUP` can be used to group files generated by `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 `AUTORCC` processing by enabling `SKIP_AUTORCC` or the broader `SKIP_AUTOGEN`.

See the `cmake-qt(7)` manual for more information on using CMake with Qt.
