AUTOMOC_MOC_OPTIONS — CMake 4.2.6 Documentation

# AUTOMOC_MOC_OPTIONS

Additional options for `moc` when using `AUTOMOC`

This property is only used if the `AUTOMOC` property is `ON` for this target. In this case, it holds additional command line options which will be used when `moc` is executed during the build, i.e. it is equivalent to the optional `OPTIONS` argument of the `qt4_wrap_cpp()` macro.

This property is initialized by the value of the `CMAKE_AUTOMOC_MOC_OPTIONS` variable if it is set when a target is created, or an empty string otherwise.

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

## EXAMPLE

In this example, the `moc` tool is invoked with the `-D_EXTRA_DEFINE` option when generating the moc file for `object.cpp`.

`CMakeLists.txt`

      add_executable(mocOptions object.cpp main.cpp)
      set_property(TARGET mocOptions PROPERTY AUTOMOC ON)
      target_compile_options(mocOptions PRIVATE "-D_EXTRA_DEFINE")
      set_property(TARGET mocOptions PROPERTY AUTOMOC_MOC_OPTIONS "-D_EXTRA_DEFINE")
      target_link_libraries(mocOptions Qt6::Core)

`object.hpp`

      #ifndef Object_HPP
      #define Object_HPP

      #include <QObject>

      #ifdef _EXTRA_DEFINE
      class Object : public QObject
      {
      Q_OBJECT
      public:

        Object();

      };
      #endif
