[boost] MSVC 2019

I recently installed Visual Studio 2019 and then Boost and Quantlib. I tried to compile Quantlb with the precompiled 1.70 boost. I go the error message: LINK : fatal error LNK1104: cannot open file 'libboost_unit_test_framework-vc142-mt-gd-x64-1_70.lib' It appears that compatibility with Visual Studio/MSVC 2019 has not been worked out in 1.70 given its release date was so close to the release date of Visual Studio 2019. I also noted the the beta for 1.71 was closed. Wondering if the beta fixes this or is there a workaround or is this a user error?
