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 QT4_WRAP_CPP() 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. 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 CMAKE_AUTOMOC variable if it is set when a target is created.

Additional command line options for moc can be set via the AUTOMOC_MOC_OPTIONS property.

By enabling the 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 AUTOGEN_TARGETS_FOLDER can be used to group the automoc targets together in an IDE, e.g. in MSVS.

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