//! [description]
Creates rules for calling the \l{moc}{Meta-Object Compiler (moc)} on the given
source files. For each input file, an output file is generated in the build
directory. The paths of the generated files are added to \c{<VAR>}.

\note This is a low-level macro. See the \l{CMake AUTOMOC Documentation} for a
more convenient way to let source files be processed with \c{moc}.
//! [description]

//! [arguments]
You can set an explicit \c{TARGET}. This will make sure that the target
properties \c{INCLUDE_DIRECTORIES} and \c{COMPILE_DEFINITIONS} are also used
when scanning the source files with \c{moc}.

You can set additional \c{OPTIONS} that should be added to the \c{moc} calls.
You can find possible options in the \l{moc}{moc documentation}.

\c{DEPENDS} allows you to add additional dependencies for recreation of the
generated files. This is useful when the sources have implicit dependencies,
like code for a Qt plugin that includes a \c{.json} file using the
Q_PLUGIN_METADATA() macro.
