Ditto. Dub's great if you let it be your buildsystem, but as soon as you 
want to use it as a package-manager-only it becomes an uphill battle 
with dub fighting back every step of the way (I speak from experience). 
That problem is worse if your project is a library that you want 
fetchable through dub.

That's why I've been working on some PRs to fix all that. The first step 
is here (building/expanding on a flag another contributer recently added):

https://github.com/D-Programming-Language/dub/pull/572

(Although I think I may need to change --data=libs and separate system 
libs from dependency libs since linkers expect those to be passed in 
differently.)

The next step will be to add a flag to have that data get output in a 
compiler-ready argument list (your choice of compiler, of course). 
That'll let you do something comparable to "pkg-config --cflags --libs".

Then finally, a shortcut flag so you can just do something kinda like:

rdmd --build-only `dub describe --cmdargs=rdmd` src/main.d

And all your dependencies will be properly referenced (-I..., linker 
flags, etc).
