qt_android_extra_libs

与目标机一起部署的额外库。

此属性在 Qt 6.0 中引入。

注意： 该属性仅用于 Android 平台。

将复制到应用程序libs 文件夹并在启动时加载的外部库列表。例如，可用于在应用程序中启用 OpenSSL。更多信息，请参阅为 Android 添加 OpenSSL 支持。

从项目的构建树中添加额外库时，还需要在库和应用程序目标之间添加依赖关系。在部署 apk 时，使用以下项目结构可能会导致问题：

qt_add_executable(MyApp main.cpp)

set_target_properties(MyApp PROPERTIES
    QT_ANDROID_EXTRA_LIBS
        ${CMAKE_CURRENT_BINARY_DIR}/libMyService_${ANDROID_ABI}.so
)

# MyService library doesn't have any relations with MyApp
qt_add_library(MyService service.cpp)

这会导致无法确定 MyService 库是否会在 MyApp 部署前可用。最简单的解决方案是将 MyService 库添加到 MyApp 依赖关系中：

add_dependencies(MyApp MyService)

在多架构项目中添加每个架构的库时，应明确列出所有库的路径，而不是依赖CMAKE_ANDROID_ARCH_ABI 等变量来动态计算路径。

更喜欢

set(libs
    ${CMAKE_CURRENT_BINARY_DIR}/libA_x86so
    ${CMAKE_CURRENT_BINARY_DIR}/libA_x86_64.so
    ${CMAKE_CURRENT_BINARY_DIR}/libA_arm64-v8a.so
    ${CMAKE_CURRENT_BINARY_DIR}/libA_armeabi-v7a.so
)
set_target_properties(MyApp PROPERTIES QT_ANDROID_EXTRA_LIBS ${libs})

# When targeting precompiled libs
target_link_libraries(${CMAKE_PROJECT_NAME} PUBLIC libA_${ANDROID_ABI})

over：

set_target_properties(MyApp PROPERTIES
    QT_ANDROID_EXTRA_LIBS
        ${CMAKE_CURRENT_BINARY_DIR}/libA_${CMAKE_ANDROID_ARCH_ABI}.so)
