Those are OpenCL functions, so you'd normally link with '-framework
OpenCL' to get them. I notice the brew formula configures with
--disable-opencl.

I’m trying to upgrade the ImageMagick Portfile to version 7.1.0-54 and
am hitting linker errors with OpenCL.
I see that homebrew has a working version at
https://github.com/Homebrew/homebrew-core/blob/master/Formula/imagemagick.rb <https://github.com/Homebrew/homebrew-core/blob/master/Formula/imagemagick.rb>, so I’ve tried to make sure I’ve copies their setup, but am still hitting this issue, observed a year ago here, https://trac.macports.org/ticket/64087 <https://trac.macports.org/ticket/64087>.
Does anyone have a suggestion for locating these symbols?
