对不起我的英语不好

我为浏览器制作了一个插件来firebreath构建ois库，它将在firebreath上包含插件并出现错误

链接有问题？或其他？我该如何解决？

您似乎没有链接所需的库。快速的google 搜索表明您需要链接到 IOKit 框架以获取这些符号中的至少一些。

我建议您查看 Firebreath.org 上的Using Libraries页面，了解有关如何链接到 Mac 框架的信息。它看起来像这样：

find_library(FRAMEWORK_IOKIT IOKit)
target_link_libraries(${PROJECT_NAME} ${FRAMEWORK_IOKIT})

这需要在您的 add_mac_plugin 调用之后的某个地方进入 Mac/projectDef.cmake。
