qt_wrap_cpp
Synopsis
qt_wrap_cpp(<VAR> src_file1 [src_file2 ...]
[TARGET target]
[OPTIONS ...]
[DEPENDS ...])
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>.
Note: This is a low-level macro. See the CMake AUTOMOC Documentation for a more convenient way to let source files be processed with moc.
This command was introduced in Qt 5.15. You can use qt5_wrap_cpp in older versions of Qt.
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})
