qt_wrap_cpp

Creates .moc files from sources.

The command is defined in the 核心 组件对于 Qt6 package, which can be loaded like so:

find_package(Qt6 REQUIRED COMPONENTS Core)

This command was introduced in Qt 5.0.

概要

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

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

描述

Creates rules for calling the MOC (元对象编译器) 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> .

注意： This is a low-level macro. See the CMake AUTOMOC Documentation for a more convenient way to let source files be processed with moc .

自变量

可以明确设置 TARGET . This will make sure that the target properties INCLUDE_DIRECTORIES and COMPILE_DEFINITIONS are also used when scanning the source files with moc .

可以设置额外 选项 应该被添加到 moc 调用。可以查找可能的选项在 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 文件使用 Q_PLUGIN_METADATA () 宏。

范例

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