According to the BSL using Boost requires
The copyright notices in the Software [...] must be included in all copies of the Software, in whole or in part, and all derivative works of the Software, unless such copies or derivative works are solely in the form of machine-executable object code generated by a source language processor
I'm not quite sure about this sentence. Do I have to grep all copyright notices from the source files/headers for the version I use, like somebody already did (https://github.com/Tencent/mars/blob/master/Copyright%20Notice%20of%20Boost)? That would be as far as I currently see over 2000 different statements.
