Package ISIS in nixpkgs

[arunoruto]

I am currently enjoying using NixOS on all of my devices and getting into packaging some applications. I thought maybe it would be a fun project to also package ISIS into nixpkgs and make it there available too! The main benefit would be to enable it to be installed anywhere you want, like it is a native CLI/GUI tool, but still keep the dependencies under control, i.e., no dependency hell like in arch.

Now, building via conda would not be feasible, since it isn't as reproducible as Nix needs it to be (solving the environment can get you different packages depending when you resolve them, or they are not found after a certain period of time). I was wondering if it would be possible to use the tarball found on anaconda to run it! I already tried to fetch and run it, but there are missing dependencies (mainly linking libraries). If someone is eager to see the beginning, here is a link to the package.nix file:
https://github.com/arunoruto/flake/blob/5af036b25b3c4c30eb37e63154ab725a51ab71d9/pkgs/isis/package.nix (if I succeed in packaging it, I will probably move it to nixpkgs and it won't be in my repo anymore, thats the reason for the specific commit).

Hope to get some input or help on this!

Okay, I kinda got most of the things with the current setup:

{
  lib,
  stdenv,
  autoPatchelfHook,

  # runtime
  geos,
  opencv,
  xercesc,
  qt5,
  libsForQt5,
}:
let
  pname = "isis";
  version = "8.3.0";

in
stdenv.mkDerivation {
  inherit pname;
  inherit version;

  src = builtins.fetchTarball {
    url = "https://anaconda.org/usgs-astrogeology/${pname}/${version}/download/linux-64/${pname}-${version}-0.tar.bz2";
    sha256 = "sha256:0b0wlb9z9p5liws38bhbjvjpb2603355bwbkgv5x81p7pyf4wkdi"; # 8.3.0
  };

  buildInputs = [
    xercesc
  ];

  nativeBuildInputs = [
    autoPatchelfHook
  ];

  autoPatchelfIgnoreMissingDeps = [
    # "libgeos.so.3.12.0"
    # "libopencv_core.so.407"
    # "libopencv_imgproc.so.407"
    # "libqwt.so.6.2"

    "libisis.so"
    "libapollo.so"
    "libcassini.so"
    "libchandrayaan1.so"
    "libclementine.so"
    "libclipper.so"
    "libcspice.so.67"
    "libdawn.so"
    "libgalileo.so"
    "libhayabusa.so"
    "libhayabusa2.so"
    "libkaguya.so"
    "liblo.so"
    "liblro.so"
    "libmer.so"
    "libmessenger.so"
    "libmex.so"
    "libmgs.so"
    "libmro.so"
    "libnear.so"
    "libnewhorizons.so"
    "libodyssey.so"
    "libosirisrex.so"
    "librosetta.so"
    "libtgo.so"
    "libviking.so"
  ];

  preBuild = ''
    addAutoPatchelfSearchPath ${qt5.qtbase}  ${libsForQt5.qwt}
  '';

  installPhase = ''
    runHook preInstall

    mkdir -p $out
    cp -r . $out

    ln -s ${geos}/lib/libgeos.so $out/lib/libgeos.so.3.12.0
    ln -s ${opencv}/lib/libopencv_core.so $out/lib/libopencv_core.so.407
    ln -s ${opencv}/lib/libopencv_imgproc.so $out/lib/libopencv_imgproc.so.407
  '';

  meta = with lib; {
    homepage = "https://isis.astrogeology.usgs.gov";
    description = "A digital image processing software package to manipulate imagery collected by current and past NASA and International planetary missions";
    license = licenses.cc0;
    platforms = platforms.linux;
    maintainers = with maintainers; [ arunoruto ];
  };
}

The only thing which confuses me is the lack of the libraries listed in autoPatchelfIgnoreMissingDeps (uncommented). I suppose they should be contained in the lib/ folder of the tarball, at least according to the share/info/paths.json file which lists them all there, but I am unable to find them...
The only thing I can find are the include/isis files which resemble the final lib files I need. But I am unsure on how to compile them... Sure it is C/C++, but it would be nice to know if I need some additional arguments and which compiler is best to use here...
