As you can see Boost_LIBRARIES is empty, but

man cmake says:

Boost_LIBRARIES Link these to use the Boost libraries that you specified, not cached

This is expected behavior. Boost_LIBRARIES gives you the libraries you need to link against, but it only does so if you've asked the Boost module to find specific libraries, e.g., "filesystem", using the COMPONENTS argument to FindPackage:

  find_package(Boost COMPONENTS filesystem)
