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
