They're not.

Wireshark is built with many external libraries:

	1) the "system libraries" - libc on most UN*Xes, libSystem on macOS (just a name difference), and a bunch of libraries on Windows;

	2) the Glib libraries from the GTK+ project;

	3) Qt, if the program being built is Wireshark;

	4) various other libraries.

GLIB2_LIBRARIES just refers to the Glib libraries.

Try wsutil.  That's linked with the Winsock libraries on Windows, and most if not all of the *other* extcap programs are built with it; it may be required by the common extcap code.
