Update Boost #49
Description
Currently we need to use b2 directly to build Boost, which is bad due to each platform building Boost on their own way. Updating on one command requires updating all of the others, and there are many incompatible settings among them.
Full support for CMake has been added in version 1.86 which eliminates the reason to use b2 and its scripts directly. It can solve this problem of multi-platform Boost building.
