Comment(by GregWeber):

 DEPENDS presumably wants *just* a file path. In Yesod, we allow our users
 to configure where their templates will be located.

 {{{
 module Settings (hamletFile) where

 hamletFile :: FilePath -> Q Exp
 hamletFile f = "myTemplateDir/" ++ f
 }}}

 {{{
 module UseTemplate where
 import Settings

 $(renderHamlet $(hamletFile "myfile.hamlet"))
 }}}

 Is there a way to do this in a compiler pragma?
