No, it seems be require "set( PROJECT_NAME PCAP )"  (upper-case). Why?
Look in pcap/export-defs.h:

#if defined(_WIN32)
  #ifdef BUILDING_PCAP
    /*
     * We're compiling libpcap, so we should export functions in our
     * API.
     */
    #define PCAP_API_DEF    __declspec(dllexport)
  #else
    #define PCAP_API_DEF    __declspec(dllimport)
  #endif

Otherwise the generated *.make files says '-DBUILDING_pcap'.
Thus your wpcap.dll exports nothing. But this produces PCAP.dll.
But I'm not familiar with Cmake.

Not sure, but my cmake supports:
  cmake -G "Visual Studio 14 2015 Win64" ..

(Win32 is implicit).
