ImageMagick: CImg.h: In member function 'cimg_library::CImg<T>& cimg_library::CImg<T>::load_magick(const char*)': #400

README says GraphicsMagick is supported as well as ImageMagick. Examples using GraphicsMagick for cimg_use_magick though, which is a different library.

# Flags to enable native support of most classical image file formats, using the Magick++ library.
# ( http://www.imagemagick.org/Magick++/ )
MAGICK_DEFINE = -Dcimg_use_magick
MAGICK_INCDIR = $(shell pkg-config --cflags GraphicsMagick++ || echo -I$(USR)/$(INCLUDE)/GraphicsMagick)
MAGICK_CFLAGS = $(MAGICK_DEFINE) $(MAGICK_INCDIR)
MAGICK_LIBS = $(shell pkg-config --libs GraphicsMagick++ || echo -lGraphicsMagick++)

Compiling for ImageMagick produces errors. Compile flags:

CXXFLAGS="-Dcimg_use_magick $(pkg-config --cflags Magick++)"
LDLIBS="$(pkg-config --libs Magick++)"

Errors:

Note about their independence on http://www.graphicsmagick.org/

GraphicsMagick is originally derived from ImageMagick 5.5.2 as of November 2002 but has been completely independent of the ImageMagick project since then.
