Hi Tom - GR, UHD, and Volk will all build correctly using Boost 1.70.0 ...
except that Boost 1.70.0's cmake scripts are broken, and they are installed by
default. So, if you insist on using 1.70.0 then you'll want to find a creative
way around them -- my recommendation is to just not use 1.70.0 at all, and I'd
guess GR & other projects will block using it in the future. By "broken" I mean
that the Boost libraries used for linking within CMake are not set properly ...
but the headers are! So, compiling works but linking doesn't. There is no good
workaround just yet, even though the Boost folks have fixed the code && say it
will be part of the 1.71.0 release whenver that happens. If you revert back to
1.69.0 then all should be well, since it either doesn't provide cmake scripts
or those scripts are not installed. Hope this is useful! - MLD
