deepin pr auto review

关键摘要:

• 在CMakeLists.txt文件中，find_package函数的调用顺序似乎已经更改，需要确认新的依赖查找是否正确。
• option命令的使用可能改变了用户配置插件的选项行为，需要确认这一改动是否符合预期。
• 在if("${QT_VERSION_MAJOR}" STREQUAL "5")和elseif("${QT_VERSION_MAJOR}" STREQUAL "6")分支中，set(XDG_ICON_VERSION_MAJOR ...)的调用可能依赖于Qt5XdgIconLoader_VERSION_MAJOR的值，但当前的调用顺序没有反映这种依赖关系。
• list(APPEND QT_LIBS ...)的调用似乎在添加Qt5::X11Extras，但在其他地方没有看到类似的操作，需要确认这一改动是否必要。
• pkg_check_modules的调用似乎在查找依赖，但Deps变量在后续代码中没有被使用，需要确认这一改动是否必要。

是否建议立即修改:
是
