C++ API

Using a Qt module's C++ API requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake .

構建采用 CMake

使用 find_package() command to locate the needed module component in the Qt6 包：

find_package(Qt6 REQUIRED COMPONENTS StateMachine)
target_link_libraries(mytarget PRIVATE Qt6::StateMachine)

更多細節，見構建采用 CMake 概述。

采用 qmake 構建

使用 find_package() command to locate the needed module component in the Qt6 包：

find_package(Qt6 REQUIRED COMPONENTS statemachine)
target_link_libraries(mytarget PRIVATE Qt6::statemachine)

更多細節，見構建采用 CMake 概述。
