Noticed this in https://bugs.webkit.org/show_bug.cgi?id=221726 where Source/cmake/PlatformJSCOnly.cmake was modified but the build was not triggered on those bots. Within Source/cmake the following should ideally happen. All CMake builds should be triggered when anything Find*.cmake, WebKit*.cmake or OptionsCommon.cmake are modified. All CMake builds on Windows should be triggered when OptionsMSVC.cmake is modified. Platform specific builds should be triggered when Options<Name>.cmake is modified. It would probably be nice if the Platform<Name>.cmake changes are also flagged per platform.
