参考:Qt 项目(CMake)设置国际化支持

1.在工程手动创建languages文件夹

2.修改CMakeLists.txt

set(TS_FILES
    "${CMAKE_SOURCE_DIR}/languages/aidi_zh_CN.ts"
    "${CMAKE_SOURCE_DIR}/languages/aidi_en_US.ts"
)

# 模拟更新和发布的命令代码
find_program(LUPDATE_EXECUTABLE lupdate)
find_program(LRELEASE_EXECUTABLE lrelease)

# 生成ts和qm文件
foreach(_ts_file ${TS_FILES})
    execute_process(
        COMMAND ${LUPDATE_EXECUTABLE} -recursive ${CMAKE_SOURCE_DIR} -ts ${_ts_file})
    execute_process(
        COMMAND ${LRELEASE_EXECUTABLE} ${_ts_file})
endforeach()

3.在qml上随便添加一下文字内容

例如:

import QtQuick 2.15
import QtQuick.Window 2.15

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    Text {
        id: name
        text: qsTr("测试")
    }
}

文本需要使用qsTr包裹

4.执行CMake
