l/boost-1.70.0-x86_64-1.txz
Shared library .so-version bump.
Note: Boost now provides its own BoostConfig.cmake config file, and it may
not work with all existing code (here, calligra stumbled over it). At this
point it's not clear if the included cmake config files are buggy, or if
affected projects need to change something in order to use them, but there's
an easy workaround to use cmake's FindBoost.cmake (as was used previously).
Add this to the call to cmake from any affected project (if cmake fails with
an error: “No suitable build variant has been found.”):
