I want to create a Swift module for [SDL2](http://libsdl.org), but it doesn’t support `pkg-config`. Instead, it uses its own tool called `sdl2-config`, which works in very much the same way. Is there any way to tell the Swift PackageManager to use that instead of `pkg-config`?

Alternatively, how do I specify the following flags in my `Package.swift`?

```swift
$ sdl2-config --libs --cflags
-L/usr/local/lib -Wl,-rpath,/usr/local/lib -Wl,--enable-new-dtags -lSDL2
-I/usr/local/include/SDL2 -I/opt/vc/include -I/opt/vc/include/interface/vcos/pthreads -I/opt/vc/include/interface/vmcs_host/linux -D_REENTRANT

```

Thanks.
