How do I write conda recipes for dynamically linked libraries?

I first wrote a bash script to create a conda evironment and installs the xerus library and all of its dependencies.

From this script I then tried to create a conda package. Although it works on my machine (even after uploading to anaconda.org) it does not work for my colleagues. The bash script however does.

I assume that I made a simple mistake in the specification of the meta.yaml or build.sh. Can you tell me where I went wrong?

Install script

#!/bin/bash
ENVNAME="${1}"
set -e

if [ -z "${ENVNAME}" ];
then
    echo "Usage: bash install.sh <env_name>"
    exit 0
fi

read -p "Create new conda environment '${ENVNAME}' (y/n)? " answer
case ${answer:0:1} in
    y|Y )
    ;;
    * )
        exit
    ;;
esac

  summary: "A c++ library for numerical calculations with higher order tensors"
  description: |
    The Xerus library is a general purpose library for numerical calculations with higher order tensors, Tensor-Train Decompositions / Matrix Product States and other Tensor Networks.
    The focus of development was the simple usability and adaptibility to any setting that requires higher order tensors or decompositions thereof.
