QT_DEPLOY_TRANSLATIONS_DIR

用于在某些目标平台上部署 Qt 翻译的前缀相对子目录。

该变量由名为QT_DEPLOY_SUPPORT 的脚本定义。它仅应在安装过程中的部署环节或构建后规则中使用。

注意：这是一个 低级部署 API 变量，仅应用于高级用例，即那些未被更高层级的 API 命令（如qt_generate_deploy_app_script）涵盖的情况。

该变量于 Qt 6.5 中引入。

项目应在部署脚本中使用 `QT_DEPLOY_TRANSLATIONS_DIR `，以避免硬编码用于部署翻译的特定目录。

QT_DEPLOY_TRANSLATIONS_DIR 默认值为translations 。若要更改QT_DEPLOY_TRANSLATIONS_DIR 的值，请在包含QT_DEPLOY_SUPPORT 之前，在项目部署脚本中进行设置。

QT_DEPLOY_TRANSLATIONS_DIR 路径是相对于QT_DEPLOY_PREFIX的。

在 macOS 或 Windows 上部署时，该变量无实际意义。

示例

cmake_minimum_required(VERSION 3.16...3.22)
project(MyThings)

# The following CMAKE_INSTALL_*DIR variables are used to initialize their
# QT_DEPLOY_*_DIR counterparts.
set(CMAKE_INSTALL_BINDIR "mybindir")
set(CMAKE_INSTALL_LIBDIR "mylibdir")
set(CMAKE_INSTALL_LIBEXECDIR "mylibexecdir")

find_package(Qt6 REQUIRED COMPONENTS Core)
qt_standard_project_setup()

qt_add_executable(MyApp main.cpp)

set(deploy_script "${CMAKE_CURRENT_BINARY_DIR}/deploy_MyApp.cmake")
file(GENERATE OUTPUT ${deploy_script} CONTENT "

set(QT_DEPLOY_PLUGINS_DIR \"mypluginsdir\")
set(QT_DEPLOY_TRANSLATIONS_DIR \"i18n\")

include(\"${QT_DEPLOY_SUPPORT}\")

qt_deploy_runtime_dependencies(
    EXECUTABLE \"\${QT_DEPLOY_BIN_DIR}/$<TARGET_FILE_NAME:MyApp>\"
)")

install(SCRIPT ${deploy_script})
