[Haskell-beginners] Libexiv2, cabal and C++

Dear Haskellers, I wrote a simple FFI binding to libExiv2 ( https://bitbucket.org/eklerks/libexiv2bindings/src), which is a library for reading exif tags from image files. I want to use cabal as build system, but I don't have a clue how to use it in this case. Normally it works like a charm. But because I have to first create a c-wrapper library around the C++ code, it becomes very complicated. IDoes anyone have some good resources I can look into? With kind regards, Edgar Klerks
