It allows performing certain low level functions such as signing messages or connecting to the debug function on nodes (currently disabled by I believe). Not generally needed.
Got it

Thanks
Another question: Boost pre-compiled binaries have either static and shared versions.
After the cmake step I guess Project.sln should point to static ones by itself...or not?
Thanks
boost pre-compiled libraries are shared versions (useful if you don't want to compile boost and you don't plan to use your binaries on another computer)
although compiling static boost libraries is not a great task
cd c:\boost_1_63_0
bootstrap.bat
b2 --toolset=msvc variant=release link=static threading=multi runtime-link=static address-model=64
boost static lib have a "s" in their name
http://www.boost.org/doc/libs/1_42_0/more/getting_started/unix-variants.html#library-naminglibraries are built in stage/lib folder
btw, when i updated cmake to 3.8 (from 3.4.3), i guess findboost has changed because i must now type
cmake -G "Visual Studio 14 2015 Win64" -DBOOST_ROOT=c:/local/boost_1_63_0 ..
with forward slash instead of
cmake -G "Visual Studio 14 2015 Win64" -DBOOST_ROOT=c:\boost_1_63_0 -DBOOST_LIBRARYDIR=c:\boost_1_63_0\stage\lib ..
previously (and with backslash)
