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