qt_wrap_cpp

Creates .moc files from sources.

The command is defined in the Core component of the Qt6 package. Load the package with:

find_package(Qt6 COMPONENTS Core REQUIRED)

Synopsis

qt_wrap_cpp(<VAR> src_file1 [src_file2 ...]
            [TARGET target]
            [OPTIONS ...]
            [DEPENDS ...])

If versionless commands are disabled, use qt6_wrap_cpp() instead. It supports the same set of arguments as this command.

Description

Creates rules for calling the Meta-Object Compiler (moc) on the given source files. For each input file, an output file is generated in the build directory. The paths of the generated files are added to <VAR>.

Arguments

You can set an explicit TARGET. This will make sure that the target properties INCLUDE_DIRECTORIES and COMPILE_DEFINITIONS are also used when scanning the source files with moc.

You can set additional OPTIONS that should be added to the moc calls. You can find possible options in the moc documentation.

DEPENDS allows you to add additional dependencies for recreation of the generated files. This is useful when the sources have implicit dependencies, like code for a Qt plugin that includes a .json file using the Q_PLUGIN_METADATA() macro.

Examples

set(SOURCES myapp.cpp main.cpp)
qt_wrap_cpp(SOURCES myapp.h)
add_executable(myapp ${SOURCES})
