At least when compiling with GHC, Cabal exposes only packages which are 
mentioned under Build-Depends. That is, if a package is missing in 
Build-Depends, the project cannot be compiled. It is however possible to 
forget modules in the Exposed-Modules and Other-Modules section and GHC 
finds them anyway.
