AUTOMOCΒΆ
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.
