This should work since Cabal-1.14. Can you show, how exactly you added the 
dependency to the executable?

If it does not work, you may add Hs-Source-Dirs of the library to the 
executable. However this means that GHC will recompile the library 
modules, yielding more compile time and more disk space consumption.
