Description: Replace ImageMagick with GraphicsMagick for build
 Current security policies in ImageMagick disable reading from PDFs, which
 is used in parts of the manual build.  There's no stock CMake module (yet)
 to substitute for FindImageMagick.cmake, so fill in the required variables
 manually.
