System: Windows, VS 2017; CMake 3.8-3.10
Currently boost build with the superbuild cannot be found with CMake's find command.
Reason is that the current boost version does not support all MSVC toolset versions (we need 14.2) and CMake does not find this toolset version (14.2).
Workarround: boost.cmake sets the MSVC version vor the toolset to 14.1. This fix should be removed as soon we have updated to a boost and cmake that can handle toolsets >14.1.
