such feature was already requested by Robert Dockins in libraries list at June 8. He wrote:

"This brings up a feature I have sometimes wanted from Cabal. I'd like to be able to say the following: "Cabal, find and use package X if it exists. Furthermore, when CPPing source code, set a #define HAS_PACKAGE_X so I can do conditional compilation based on the (non-) avaliablility of package X". Is this possible? Difficult? It seems like a nice way to handle a number of problems, including platform- dependencies (as here) and optional features with external dependencies."

you can add your voice to the peoples requesting this feature (i need it, too)

I have some changes to Cabal partly finished that will address this. Don't worry, it's coming. Cheers, Simon
