如何使用nix测试共享库？

问题描述

我有以下推导：

{ stdenv,cmake,python38,enableCfp ? false,enableZforp ? false,enableZFPy ? false,enableutilities ? true,enableExamples ? false,enableTestingSmall ? true,enableTestingLarge ? false,enableSharedLibs ? true
}:

let
  # FIXME: Pretty sure this should use buildPythonPackage or something
  pythonEnv = python38.withPackages (ps: [
    ps.cython
    ps.numpy
  ]);
in
stdenv.mkDerivation rec {
  pname = "zfp";
  version = "0.5.5";
  src = builtins.fetchTarball {
    url = "https://computing.llnl.gov/projects/floating-point-compression/download/zfp-0.5.5.tar.gz";
    sha256 = "1l9skghq2iyj4h4ql9z49rqm07bvins6bff0cg8nmfnhp5inww33";
  };

  doCheck = enableTestingSmall || enableTestingLarge;

  cmakeFlags = []
    ++ stdenv.lib.optional enableCfp "-DBUILD_CFP=ON"
    ++ stdenv.lib.optional enableZforp "-DBUILD_ZFORP=ON"
    ++ stdenv.lib.optional enableZFPy "-DBUILD_ZFPY=ON"
    ++ stdenv.lib.optional (!enableutilities) "-DBUILD_UTILITIES=OFF" # Default on
    ++ stdenv.lib.optional enableExamples "-DBUILD_EXAMPLES=ON"
    ++ stdenv.lib.optional (!enableTestingSmall) "-DBUILD_TESTING_SMALL=OFF" # Default on
    ++ stdenv.lib.optional enableTestingLarge "-DBUILD_TESTING_LARGE=ON"
    ++ stdenv.lib.optional (!enableSharedLibs) "-DBUILD_SHARED_LIBS=OFF"
    ++ stdenv.lib.optional (!doCheck) "-DBUILD_TESTING=OFF";

  nativeBuildInputs = [ cmake ]
    ++ stdenv.lib.optional enableZFPy pythonEnv;
}

虽然生成正确的库，但测试似乎并未使用它们。我得到：

/build/source/build/nix/store/iay9p2wvwrv3x2352qwk0jhbpkx45ibl-zfp-0.5.5/bin/testzfp: error while loading shared libraries: libzfp.so.0: cannot open shared object file: No such file or directory

应该如何将生成的库包含在LD_LIBRARY_PATH（？）

谢谢。
