Boost 1.64 fixes for release
I got some bug reports that FindBoost.cmake
from CMake 3.8.0 does not work with Boost 1.64 whereas the CMake master branch works as expected. I prepared an update for the release
branch where I cherry-picked all missing commits. Both branches now have an identical find module.
Please consider merging this branch to have a working Boost lookup in CMake 3.8.1.
