[Haskell-cafe] Different results when building wxHaskell on Cabal and Stack

Hello cafe, Lately, I wanted to try wxHaskell, so I downloaded and install wxWidgets and added the necessary paths to %PATH%. The problem was that when trying to build, cabal would have no problem at all, while stack sends me into battle with my path, complaining about missing header and executable files and so on. I don't understand why stack is having such a hard time when cabal has no trouble at all. I know that they are not the same, but I still think that it is weird that stack is acting like that. Thanks for your help, Yotam
