Compiling MagickWand program

[ersist]

Hello, i was trying to compile the code wand.c (the first at this link http://www.imagemagick.org/script/magick-wand.php) but i got an error: "error: pkg-config --cflags --libs MagickWand: File o directory non esistente"... Why? I have installed pkg-config and wand/MagickWand.h is in the directory of my project. Maybe am i missing something??
Thank youuu
