New to D (and enjoying the learning..) I've probably missed something obvious but I'm slightly confused with the best way to achieve a simple build.
I like to keep my reusable modules in a directory outside of the project directory so I can use them on another project for example.
I do :-
rdmd app.d and get a fail.
No problems, I can run rdmd thus :-
rdmd -I../EXTERNALMODULES app.d
and it all compiles nicely.
Same goes for dmd just use dmd -I and it compiles the code clean.
I'd normally just have a CPPFLAGS=... line in a classic Makefile to do this for me but can't see a native D way of doing it. I looked at dub and that that :-
dub add-path ../EXTERNALMODULES
would do the trick but it doesn't make a difference (the path is added to the relevant json file in ~/.dub), I also tried add-local but no difference. I was expecting it to add something to dub.sdl but that hasn't changed since I created the project.
TLDR: How do I automatically specify the -I to the compilers so I don't need to specify it manually each time ?
