When trying to build target Diffusion Release (branch: current master) with Ubuntu 16.04 and gcc-7 the build fails with the following error:

/home/jakob/dev/MITK-sb-diffusion/ep/src/DCMQI/jsoncpp/jsoncpp.cpp:234:14: error: 'scoped_ptr' in namespace 'std' does not name a template type
 typedef std::scoped_ptr<CharReader> const  CharReaderPtr;

In the same file (jsoncpp.cpp) at lot more similar errors also occur.
