AUTOMOC
|
|
-------
|
|
|
|
Should the target be processed with automoc (for Qt projects).
|
|
|
|
AUTOMOC is a boolean specifying whether CMake will handle the Qt ``moc``
|
|
preprocessor automatically, i.e. without having to use the
|
|
:module:`QT4_WRAP_CPP() <FindQt4>` or QT5_WRAP_CPP() macro. Currently Qt4 and Qt5 are
|
|
supported.
|
|
|
|
When this property is set ``ON``, CMake will scan the
|
|
source files at build time and invoke moc accordingly.
|
|
|
|
* If an ``#include`` statement like ``#include "moc_foo.cpp"`` is found,
|
|
the ``Q_OBJECT`` class declaration is expected in the header, and
|
|
``moc`` is run on the header file. A ``moc_foo.cpp`` file will be
|
|
generated from the source's header into the
|
|
``<CMAKE_CURRENT_BINARY_DIR>/<TARGETNAME>_autogen/include``
|
|
directory which is automatically added to the target's
|
|
:prop_tgt:`INCLUDE_DIRECTORIES`. This allows the compiler to find the
|
|
included ``moc_foo.cpp`` file regardless of the location the original source.
|
|
However, if multiple source files in different directories do this then their
|
|
generated moc files would collide. In this case a diagnostic will be issued.
|
|
|
|
* If an ``#include`` statement like ``#include "foo.moc"`` is found,
|
|
then a ``Q_OBJECT`` is expected in the current source file and ``moc``
|
|
is run on the file itself. Additionally, header files with the same
|
|
base name (like ``foo.h``) or ``_p`` appended to the base name (like
|
|
``foo_p.h``) are parsed for ``Q_OBJECT`` macros, and if found, ``moc``
|
|
is also executed on those files. ``AUTOMOC`` checks multiple header
|
|
alternative extensions, such as ``hpp``, ``hxx`` etc when searching
|
|
for headers. The resulting moc files, which are not included as shown
|
|
above in any of the source files are included in a generated
|
|
``moc_compilation.cpp`` file, which is compiled as part of the
|
|
target.
|
|
|
|
This property is initialized by the value of the :variable:`CMAKE_AUTOMOC`
|
|
variable if it is set when a target is created.
|
|
|
|
Additional command line options for moc can be set via the
|
|
:prop_tgt:`AUTOMOC_MOC_OPTIONS` property.
|
|
|
|
By enabling the :variable:`CMAKE_AUTOMOC_RELAXED_MODE` variable the
|
|
rules for searching the files which will be processed by moc can be relaxed.
|
|
See the documentation for this variable for more details.
|
|
|
|
The global property :prop_gbl:`AUTOGEN_TARGETS_FOLDER` can be used to group the
|
|
automoc targets together in an IDE, e.g. in MSVS.
|
|
|
|
Source C++ files can be excluded from :prop_tgt:`AUTOMOC` processing by
|
|
enabling :prop_sf:`SKIP_AUTOMOC` or the broader :prop_sf:`SKIP_AUTOGEN`.

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