AUTOMOC_COMPILER_PREDEFINES

Boolean value used by 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 CMAKE_CXX_COMPILER_PREDEFINES_COMMAND when

• AUTOMOC is enabled,
• AUTOMOC_COMPILER_PREDEFINES is enabled,
• CMAKE_CXX_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 AUTOGEN_BUILD_DIR, is passed to moc as the argument to the --include option.

By default AUTOMOC_COMPILER_PREDEFINES is initialized from CMAKE_AUTOMOC_COMPILER_PREDEFINES, which is ON by default.

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