[CMake] Can't find Boost with Visual Studio 2017

[Volker Enderlein]

Hi David,

Boost changed its naming scheme starting from version 1.66. So its not 
your fault but the FindBoost.cmake does not know how to handle the new 
scheme. Try to use one of the 3.11.0-rc[1-3] versions that has the 
proper naming scheme handling of 1.66 or use the 1.65.1 that is the last 
version with the old naming scheme.

Cheers Volker
