Hello guys,
I'm pretty sure the answer is no, but I was hoping to get some extra
insight / best practices. The problem can be summarised by this SO question
(not the OP, but I have the same problem):
http://stackoverflow.com/questions/15731170/cabal-how-to-add-text-file-as-a-build-dependency
As
Distribution.Simple
main :: IO ()
main = doThisBeforeInstall defaultMain
-
Then you specify in your .cabal file that the Build-Type is Custom.
Best regards,
Daniel Díaz.
