It seems to be a little more complicated. Each compiler has a installExe and installLibs (or a joined install) functions which also mix collecting files and copying them. I think that the right thing to do would be to abstract away those compiler functions in a module with the same interface for all of them. Distribution.Simple.Compiler seems to be place. Moreover, something has to be done to decouple the file gathering from the copying phase in this functions, but I am not the correct person to decide how to do it. Any thoughts?

Hi!
I'd like to get involved in haskell development and I think this could be a good start. I don't know how much time I'll have to do this, but if you give me that advice I'll try to implement this functionality.
Great.
The place to look is the Distribution.Simple.Install module in the Cabal library. It currently directly calls functions like copyFileVerbose, copyDirectoryRecursiveVerbose and copyFiles.
You'll want to look at each case and instead gather the files to be installed into one big list and then use a single call to copyFiles.

So as you say, the way to do this would be to generate a list of files that will be installed. This can be used to later uninstall.
If you want to work on this feature I can provide some advice on how to implement it. It'll need a bit of work to restructure the install code so that it actually produces a list of things to install, rather than just installing them.
