How does one set compiler options in DlangIDE?

[WhatMeWorry via Digitalmars-d-ide]

I've poked and prodded in all the windows, but I can't find 
anything.  I compile with dmd but I can't even add a 
-Ithis/is/a/path to the compiler.

Running (in 
/home/generic/.dub/packages/dlangide-0.6.12/workspaces/sample1/sampleproject2): /home/generic/dlang/dub/dub build --force --build-mode=allAtOnce --build=debug
Performing "debug" build using dmd for x86_64.
sampleproject2 ~master: building configuration "application"...

'dlangui/core/logger.d' which cannot be read
import path[0] = source/
import path[1] =

import path[2] =

dmd failed with exit code 1.

I've played with
Project > Project Settings > Build and
Project > Project Settings > Run and Debug

But no matter what I put in the fields, I don't see any changes 
to the command line.
