How to test a DUB-based library during development?

[DanielG]

Ah, thank you! I replaced:

     "libs-windows-x86-dmd"

with:

     "sourceFiles-windows-x86-dmd" (and added a .lib suffix)


and now everything works as expected.

I see now that I was using "libs" improperly. It seems more for 
system-wide libraries / things in the library search path, not to 
be used for individual .lib files.

Thanks again, you saved me many hours this morning :)
