Cabal has both --prog-option= and --prog-options=. The latter tokenises the options and passes them as separate flags (like what the shell does), the former passes the whole arg as one option. So you want to use: cabal build --ghc-option=-DFOO="\"hello world\"" When you want to put this in the .cabal file, use cpp-options (not ghc-options) and you can use Haskell String syntax for options that contain spaces.
