Linker error on dub release build #24
Description
squiz-box has been working wonderfully in a debug/plain build, but a release/release-debug build produces linker errors. I'm currently learning D (my background is C/C++) so this might be something I'm doing wrong.

perhaps `.d` files need to be added on the command line, or use `-i` to compile imports
