title: Copy link library files for conda build
body: <p>I am trying to prepare a conda build for a <a href="https://github.com/abyzovlab/CNVnator" rel="nofollow noreferrer">package</a> and the package depends on <a href="https://github.com/samtools/samtools/releases" rel="nofollow noreferrer">samtools</a> libraries. The user needs to copy the library files into the package directory for compilation. Here is the installation instruction of the package.</p>
  
  <pre><code>ln -s &lt;path_to_samtools_dir&gt; samtools
  make OMP=no # without parallel support
  </code></pre>
  
  <p>I am not sure how to configure that part for conda-build.</p>
  
  <p>The requirements section of my <code>meta.yml</code> file</p>
  
  <pre><code>requirements:
    build:
      - {{ compiler('c') }}
      - samtools
      - htslib
      - cmake
      - readline
      - zlib
    Host:
      - samtools
      - htslib
    run:
      - samtools
      - htslib
      - python
      - numpy &gt;=1.16
      - root
      - matplotlib
      - readline 
  </code></pre>
