The symbols.filter script contains the list of symbols that are local and visible outside of the webkit library. Source/cmake/OptionsGTK.cmake contains the following line: set(VERSION_SCRIPT "-Wl,--version-script,${CMAKE_SOURCE_DIR}/Source/autotools/symbols.filter") However we don't seem to be using it and that variable is not referenced anywhere else (and that's anyway the old path, it was moved to Tools/gtk when we switched to cmake).

I guess the eflsymbols.filter file is not up to date, or it's only for WebKit1, or whatever, anyway I'll add the VERSION_SCRIPT to LDFLAGS only for GTK then.
