C++ 架构x86_64的未定义符号：链接错误

我有一个stellarium插件，它在Ubuntu上构建得很好，但当我试图在MacOSX上构建它时会抛出一个错误。我试图更改CMakeLists.txt文件以使其在OSX上兼容，但我反复遇到相同的错误。我收到的信息是：

您如何看待此错误：

ld:warning:未找到选项'-L/src'的目录。

是否可以发布CMake配置消息。生成过程似乎缺少某些环境变量。出现问题的行位于CMakeLists.txt中：“LINK_DIRECTORIES（${build_DIR}/src）”尝试打印“build_DIR”的值。类似于“message”（“Build Dir是：“${Build_Dir}”）在你身上。txt@AmeyaVS我试着打印它，但它返回一个空字符串。我也试过其他内置插件，但同样的事情发生了。你能在Ubuntu中尝试一下，看看有什么不同。运行make命令如下：make VERBOSE=1，它将显示完整的编译命令行。比较两个插件的日志cOSX与Ubuntu
