The CURLOPT definitions are created by a macro, so you won't find that
exact string in curl.h. This problem is most commonly caused by having
several copies of libcurl on the system and the compiler picking up
the wrong one. Check the -I options on your compiler command-line to
make sure that it's picking up the version of libcurl that you're
interested in. Then, do the same with the -L options to make sure your
app links against the correct version of the library, too.
