node.js - gyp - 如何指定链接库风格

Question

我正在编写一个本地 Node 模块，我希望能够在发布和调试版本中构建它。

Node 模块链接到另一个库，该库在两个不同的目录中具有调试和发布版本。

现在这就是我卡住的地方 - 我如何为正在构建的当前配置指定库目录？

我尝试在configuration.debug.link_settings 键中设置它，但我收到错误:'在调试配置中不允许链接设置，在目标 binding.gyp 中找到

显然，这在跨平台方式中是不可能的。因此，希望这可以节省您几个小时的实验时间。

这是一个为 Mac 和 Windows 构建插件的 gyp 文件。

//This example assumes you have an external library 'thelibrary', located in 
//./external/thelibrary
//With the two flavors, debug and release in lib/debug and lib/release
