Searching around for those files they all appear in WebCoreJSBuiltins.cpp. In CMake this seems to correspond with line 3729 of Source/WebCore/CMakeLists.txt.

ADD_SOURCE_WEBCORE_DERIVED_DEPENDENCIES(${WEBCORE_DIR}/bindings/js/WebCoreJSBuiltins.cpp ${_objectName}Builtins.cpp)

Overall I think the issue is that there are some dependencies being expressed in CMake that are not necessarily true which is causing a lot of regeneration when there are changes.

        <pre>Here's some more information on what I'm seeing. So in this case I'm building WinCairo in Visual Studio 2015. To start I generate the project files using the following command.

perl Tools\Scripts build-webkit --wincairo --no-ninja --64-bit
