Perhaps http://www.haskell.org/cabal/release/cabal-latest/doc/users-guide/authors.html#pkg-descr
helps?

"install-includes:  filename list

    A list of header files from this package to be installed into
$libdir/includes when the package is installed. Files listed in
install-includes: should be found in relative to the top of the source
tree or relative to one of the directories listed in include-dirs.

    install-includes is typically used to name header files that
contain prototypes for foreign imports used in Haskell code in this
package, for which the C implementations are also provided with the
package. Note that to include them when compiling the package itself,
they need to be listed in the includes: field as well."
