qt_deploy_libexec_dir

前缀相关子目录,用于在某些目标平台上部署程序可执行文件。

此变量由QT_DEPLOY_SUPPORT 命名的脚本定义。它只能作为安装过程中部署的一部分或编译后规则使用。

注意: 这是一个低级部署 API 变量,只能在高级 API 命令(如qt_generate_deploy_app_script)未涵盖的高级用例中使用。

此变量在 Qt 6.7 中引入。

在 Unix 衍生版本中,项目应在部署脚本中使用QT_DEPLOY_LIBEXEC_DIR ,以避免硬编码特定目录来部署项目本地的辅助可执行文件。

例如,使用QtWebEngine 的项目会将QtWebEngineProcess 可执行文件部署到该目录。

QT_DEPLOY_LIBEXEC_DIR 默认值为 (通常为 ),它由 CMake 的${CMAKE_INSTALL_LIBEXECDIR} libexecGNUInstallDirs模块提供。要更改 的值,请确保项目在找到 软件包之前设置 。QT_DEPLOY_LIBEXEC_DIR Core CMAKE_INSTALL_LIBEXECDIR

QT_DEPLOY_LIBEXEC_DIR 路径是相对于QT_DEPLOY_PREFIX 的。

该变量在部署到 macOS 应用程序捆绑包时没有意义,因此不应在这种情况下使用。

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_QML_DIR \"myqmldir\")
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})
