If the API is not going to be available on all Windows systems, then use
LoadLibrary()+GetProcAddress() so we can at least run the other parts of
the test on these platforms. In extreme cases you may have to tweak the
test so it does not link at all with the dll it's supposed to test if
that dll may be missing on some Windows versions (e.g. Windows 95 or
Otherwise just use the standard header+link method. If in doubt, go with
with the header+link method and someone will fix the test if it does not
compile/run on Windows anymore.

The MSDN may tell you that the API is Windows 200+ or some such. But
that's not very reliable: it's quite possible the API is there and just
returns ERROR_NOT_IMPLEMENTED or some such.
