If you're indeed running Ubuntu 15.04, it's there:

    http://packages.ubuntu.com/wily/graphicsmagick

It seems that Ubuntu has split out the C and C++ libraries into multiple 
packages and http://packages.ubuntu.com/wily/libgraphicsmagick++1-dev 
looks to be ok.  Make sure you also install the main graphicsmagick 
package too.
