            Bug ID: 224089
           Summary: [CMake][GStremer] Fails to build if OpenH264 is not
                    present
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WPE WebKit
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: clopez at igalia.com
                CC: bugs-noreply at webkitgtk.org

In r275275 optional support for using OpenH264 was added.

However, this seems to be failing to build when OpenH264 is not present because of CMake trying to link with a library that is not defined
