You can use the "preGenerateCommands" to launch the adequate git 
commands. The submodule needs to be indicated using the "path" 
property :

       "preGenerateCommands" : ["git submodule update --init 
--recursive"],
       "dependencies" : {
         "theGitSubModule" : {
           "path" : "./theGitSubModulePath"
         },

I have done this before and while it worked I had to "dub build" 
twice because the project needed to be read a second time to 
discover new source files generated by the commands.

There's a PR that is supposed to fix that: 
https://github.com/dlang/dub/pull/1708
But more likely at some point git submodules will be supported 
natively.
