C++ REST SDK Dependencies
- Boost: Check, we already have Boost.
- WebSocket++: Integrated into C++ REST SDK as git submodule (git submodule update --init ...)
- zlib: Already integrated in some projects like ITK, VTK, and Poco but all of them modify zlib so that it is not linkable anymore in a generic way. MITK_USE_ZLIB seems to be a relic and MITK code uses ITK's version of zlib. So we need to integrate pure up-to-date zlib as a dependency.
