            Bug ID: 143839
           Summary: [CMake] Should be possible for an option to depend on
                    multiple options
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Enhancement
          Priority: P2
         Component: Tools / Tests
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mcatanzaro at igalia.com

Currently it's not possible for an option to depend on more than one other option. This makes it awkward to manually check whether the combination of available options is valid. For example, my patch in bug #143558 uses the following code:

WEBKIT_OPTION_DEPEND(USE_GSTREAMER_GL ENABLE_VIDEO)
WEBKIT_OPTION_DEPEND(USE_GSTREAMER_GL USE_OPENGL)
WEBKIT_OPTION_DEPEND(USE_REDIRECTED_XCOMPOSITE_WINDOW ENABLE_X11_TARGET)
WEBKIT_OPTION_DEPEND(USE_REDIRECTED_XCOMPOSITE_WINDOW USE_OPENGL)

It would be nice if that worked as expected. The current behavior is that the most recent call to WEBKIT_OPTION_DEPEND overrides the previous call.
