How to statically link Derelict SDL2 satellite libs

[eskaypee]

I'm on Linux 64 bit, all SDL libraries (-dev versions) are 
installed, dub is set up with:

     "dependencies": {
     "derelict-sdl2": "~>3.0.0-beta"
     },
     "subConfigurations": {
     "derelict-sdl2": "derelict-sdl2-static"
     },
     "libs":
     ["sdl2"]

All the SDL core library functions work fine but when I try to 
use SDL_image library's IMG_Load() or IMG_LoadTexture() I get a 
linker error, for example:

undefined reference to `IMG_LoadTexture'
collect2: error: ld returned 1 exit status
Error: linker exited with status 1
dmd failed with exit code 1.

I have:
import derelict.sdl2.image;

at the top of my program. I'm guessing that the "libs" section of 
my dub subConfiguration needs to include the name of the image 
satellite library?
