... it complain not reference to zlibversion etc

Looks like you're trying to build against a static libcurl (libcurl.a).
It's probably easier to build against libcurl.dll.a import library, assuming you have such a file.
If you're lucky, it might be as simple as renaming libcurl.a to (eg) libcurl.a_static && then copying libcurl.dll.a to libcurl.a.

When I've built Net-Curl-0.37 against static libraries, I've had to specifically link to: 
-lcurl -lrtmp -lwinmm -lcares -lwldap32 -lidn -liconv -lssh2  -lws2_32
+ -lgdi32 -lssl -lcrypto -lcrypt32  -lz

I'll try to build latest Net-Curl with perl-5.30 later today, and see how it goes for me.

Cheers,
Rob
