Regarding the inability to reference io/ssl in vcpkg

[dongyaosheng]

I am using cmake + vcpkg to reference cobalt. If I only use Boost::cobalt, there is no problem. But if I want to reference cobalt_io/cobalt_io_ssl, it seems to have some issues. Here is boost_cobalt-targets.cmake, seems no info about Boost::cobalt::io has been exported

No idea, I am not a user of vcpkg.
