build this library in tree using cmake fetchcontent

Hi, I see there is a CMakeLists.txt in this repo and I have heard an on-going effort in the Boost community to modularize the individual boost packages. What is the current status of building boost::unit_test_framework in cmake as an independent package from the rest of boost? My use case is using cmake fetchcontent from this github to include this library into the build tree of different projects, some use header only part and some use dynamic-linked library. Is this possible now with cmake?
