I'm not good at GNU Autotools stuff, sorry. Could you elaborate on this? I
don't see that "IMAGEMAGICK_LIBS" would be assigned any value in "
configure.ac". Nevertheless, on the linking stage I see:

-lMagickWand-6.Q16HDRI -lMagickCore-6.Q16HDRI

Is this what you meant? Can I just safely assign it to empty value then?

I assume adding something like:

       '(imagemagick "libMagick++-6.Q16HDRI-5")

Is this correct?

Well, I have no idea about that yet. I'm not a huge expert with
ImageMagick. Perhaps somebody could clarify on that.
