            Bug ID: 284311
           Summary: [CMake][LibWebRTC] Fix build after 287443 at main
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: dpino at igalia.com

On ARM platforms that do not support SVE, the build is failing with the following linking error:

FAILED: lib/libWPEWebKit-2.0.so.2.4.1

Changeset  287443 at main disables SVE in Source/ThirdParty/libwebrtc/Configurations/libyuv.xcconfig:

https://github.com/WebKit/WebKit/compare/865625bf942f%5E..865625bf942f#diff-2752c88e71f5346a457e0b6f67849c67ea4217f918d7966cd8561dc2a9e1765dR11

So probably a similar change should fix the build.
