I'm getting the following error with 3.15: ``` -- Found Boost: C:/projects/.local/lib/cmake/Boost-1.72.0/BoostConfig.cmake (found suitable exact version "1.72.0") found components: python27 CMake Error at C:/Program Files (x86)/CMake/share/cmake-3.15/Modules/FindBoost.cmake:342 (get_target_property): INTERFACE_LIBRARY targets may only have whitelisted properties.
