Is there a way to specify targetPath / targetName for a build directly
in the dub command line?
The use case I'm looking at, is that I want to just build the unittest
executable, but don't want it to overwrite the normal executable file.
The only solution is to specify targetPath / targetName in the unittest
configuration in the dub.json, but ideally, dub.json modifications
should not be necessary.
