It should be automatic when you detect FreeTDS header (which are
slightly different).
So something in the "configure" like scripts (depending on the build
system you are using).
Otherwise you can check for specific extensions, like for dblib you
can check presence of
"DBTDS_7_4" macro or the presence of tdsdbopen function.
For ctlib you can check presence of "CS_TDS_74".
