so the libraries are obviously there!<br>
<br>
Questions:<br>
<strong><span style="font-family:"Arial",sans-serif">What am I doing wrong?</span></strong><b><br>
<strong><span style="font-family:"Arial",sans-serif">What did I possibly misunderstand regarding the find_library command?</span></strong></b><br>
