AUTOMOC_MACRO_NAMES — CMake 4.3.0 Documentation

# AUTOMOC_MACRO_NAMES

Added in version 3.10.

A semicolon-separated list of macro names used by `AUTOMOC` to determine if a C++ file needs to be processed by `moc`.

This property is only used if the `AUTOMOC` property is `ON` for this target.

When running `AUTOMOC`, CMake searches for the strings listed in `AUTOMOC_MACRO_NAMES` in C++ source and header files. If any of the strings is found

- as the first non space string on a new line or

- as the first non space string after a `{` on a new line,

then the file will be processed by `moc`.

By default `AUTOMOC_MACRO_NAMES` is initialized from `CMAKE_AUTOMOC_MACRO_NAMES`.

See also the `INTERFACE_AUTOMOC_MACRO_NAMES` target property.

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

## Example

In this case the `Q_OBJECT` macro is hidden inside another macro called `CUSTOM_MACRO`. To let CMake know that source files that contain `CUSTOM_MACRO` need to be `moc` processed, we call:

    set_property(TARGET tgt APPEND PROPERTY AUTOMOC_MACRO_NAMES "CUSTOM_MACRO")
