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
|
