Make the icons build step optional. This way, ImageMagick is no longer a hard build dependency. For developers or users, building puzzles without nice icons is preferable to not building them at all. (Also, thanks to Michael Quevillon for pointing out very promptly that my use of 'REQUIRED' in the find_program command was implicitly depending on a version of CMake in advance of my minimum_required specification. This change fixes that too, in passing.)
