I wanna to compile C++ code in this source <https://github.com/jdeng/rbm-mnist> I have installed clang 3.4, `sudo apt-get install libmagickwand-dev`, `sudo apt-get install build-essential` , and `sudo apt-get install libmagickwand-dev`.

I found that there isn't `/usr/include/GraphicsMagick` and `Magick++.h` locates in `/usr/include/ImageMagick`.

I have run this command `clang++ --std=c++0x -o dbn -g -O2 demo.cc -lz -I /usr/include/ImageMagick -lGraphicsMagick++` but an error occurred, it is `/usr/bin/ld: cannot find -lGraphicsMagick++`

I have no idea because I already installed `libmagickwand-dev`, could you please help?
