How do you include external libraries into Haxe?

I'm trying to write a program for which I would like to use some external C++ libraries in Haxe. I can't really figure it out since the official documentation is old (http://old.haxe.org/doc/cpp/ffi) and I'm not familiar with C++ either.

So how do you do that in Haxe? I suppose I'll need to install hxcpp via haxelib, but that's about as much as I know.

For a start, check out C++ Magic by Hugh Sanderson. Much of the mentioned Compiler Metadata in that talk can be found at the Built-in Compiler Metadata page in the Haxe Manual.

He then talks briefly about metadata magic. He provides metadata for classes and functions. For classes you have the following:

@:headerClassCode(...) which injects member variables and inline functions.
@:headerCode(...) which includes external headers.
@:headerNamespaceCode(...) which allows you to add to the global namespace.
@:cppFileCode(...) which allows you to include external headers only in C++ files.
@:cppNamespaceCode(...) which implements static variables.
@:buildXml(...) which allows you to add to the build.xml file.

For function metadata you get the following:

@:functionCode(...)
@:functionTailCode(...)

Hugh states these are largely redundant as you should use untyped __cpp_(...) instead.
