If built statically, `libedit` may have a private static library dependency on a provider of the `terminfo` API (e.g., `ncurses`). This means that multiple libraries would need to be provided as the value for `LibEdit_LIBRARIES`, but the current implementation of `FindLibEdit` precludes this. This PR allows a list to be passed to `LibEdit_LIBRARIES`.
