This approach does not work for Mir GLAS.
http://forum.dlang.org/post/dfqcgdfnxmnkreywoyhl@forum.dlang.org

I can build a Mir GLAS library with DUB. But I can not do it 
automatically with DUB, but want to do it.

For example:
---
"dependencies": {
     "mir-glas": "<its recent version>"
}
---
will not work for a user because mir-glas should be prebuilded 
with the following command:

dub build --config=static --build=target-native --compiler=ldmd2 
--build-mode=singleFile --parallel

And it should be builded this way whatever compiler and dub 
options user use for his project.
