AUTOMOC_MOC_OPTIONS

Additional options for moc when using :prop_tgt:AUTOMOC

This property is only used if the :prop_tgt: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 :module:qt4_wrap_cpp() <FindQt4> macro.

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

See the :manual: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 .. code-block:: cmake

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 .. code-block:: c++

#ifndef Object_HPP
#define Object_HPP

#include <QObject>

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

  Object();

};
#endif

#endif
