AUTOMOC_COMPILER_PREDEFINES
|
|
---------------------------
|
|
|
|
.. versionadded:: 3.10
|
|
|
|
Boolean value used by :prop_tgt:`AUTOMOC` to determine if the
|
|
compiler pre definitions file ``moc_predefs.h`` should be generated.
|
|
|
|
CMake generates a ``moc_predefs.h`` file with compiler pre definitions
|
|
from the output of the command defined in
|
|
:variable:`CMAKE_CXX_COMPILER_PREDEFINES_COMMAND <CMAKE_<LANG>_COMPILER_PREDEFINES_COMMAND>`
|
|
when
|
|
|
|
- :prop_tgt:`AUTOMOC` is enabled,
|
|
- :prop_tgt:`AUTOMOC_COMPILER_PREDEFINES` is enabled,
|
|
- :variable:`CMAKE_CXX_COMPILER_PREDEFINES_COMMAND <CMAKE_<LANG>_COMPILER_PREDEFINES_COMMAND>` isn't empty and
|
|
- the Qt version is greater or equal 5.8.
|
|
|
|
The ``moc_predefs.h`` file, which is generated in :prop_tgt:`AUTOGEN_BUILD_DIR`,
|
|
is passed to ``moc`` as the argument to the ``--include`` option.
|
|
|
|
By default :prop_tgt:`AUTOMOC_COMPILER_PREDEFINES` is initialized from
|
|
:variable:`CMAKE_AUTOMOC_COMPILER_PREDEFINES`, which is ON by default.
|
|
|
|
See the :manual:`cmake-qt(7)` manual for more information on using CMake
|
|
with Qt.
