One thing I'd like to see here is to take a survey of what `send` and
`recv` signatures actually exist in the wild today. We can then remove
those `try_compile` runs from CMake's import. Further work would be to
have `libcurl` upstream do this survey too (though this is a wider set
of platforms than even CMake supports) and remove those which don't
actually appear in the wild today. In addition, the attempts can be
ordered based on platform and short circuit once one is found since
`send` can have only one actual definition.
