In SDL syntax, either at the top level, in a configuration, or 
build type:

```
versions "something" "other"
```

To be more clear: When using dub you need to put this in the dub 
file, dub.sdl or dub.json. If you want to be able to choose from 
the command line, use a configuration:

```
configuration "something" {
     versions "something"
}
```

Then you can do:
```
dub build -c=something
```

How can this be the official solution?

It should be as easy as dub build -v "something"

Arbitrary version specification is pretty suspect. For optional version 
support, there should be an official configuration that does the right 
thing, and then you select that configuration.

You also can do `DFLAGS="-version=something" dub` if you like to live on 
the edge.

Thanks for the replies. I think definitely we need a better 
documentation of this at least. It seems to have more than one 
way to do.

I tried this at first:
```
dub build -version=USE_SDL

     Error Error processing arguments: Can't parse string: bool 
should be case->> insensitive 'true' or 'false'
       Run 'dub help' for usage information.
```

Dub seems to understand my 'version' argument, but this has not 
in the help section.

And in this documentation we have more than one way to declare 
versions:
https://dub.pm/package-format-json.html#configurations

1. { "versions": ["PrintfDebugging"] }

2. like out friend said in configuration
     {
     	"name": "somepackage",
     	"configurations": [
     		{
     			"name": "glut-app",
     			"targetType": "executable",
     			"versions": ["GlutApp"]
     		}
     	]
     }

The -c argument refers to config build.
Maybe I'm confusing with package version.
But my thoughts about dub is that we need to have the best 
documentation as we can to provide a good understanding for 
newcomers in D language.
