Pascal Bach 7ccbca6010 opencv3: don't download ippicv if not enabled
On aarch64 ipp is not available but the derivation still tries to download it
leading to an error that the platform is not supported.

There is already an option to enable ipp which is disabled by default.
So the sensitive thing to do is to only download the ippicv package if
the option is enabled.

This makes opencv3 build on aarch64.

Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:

% git remote add channels git://github.com/NixOS/nixpkgs-channels.git

For stability and maximum binary package support, it is recommended to maintain custom changes on top of one of the channels, e.g. nixos-17.09 for the latest release and nixos-unstable for the latest successful build of master:

% git remote update channels
% git rebase channels/nixos-17.09

For pull-requests, please rebase onto nixpkgs master.

NixOS Linux distribution source code is located inside nixos/ folder.
