But, on Windows, `D:` means `Relative path to the current directory on that drive`. Therefore, cmake understand the path `D:` with `Relative path to the current directory on that drive`. And then, vcpkg is looking for `vcpkg.json` at `D:\WebKitBuild\Release\`, but there are no `vcpkg.json`. To fix this, webkit-build must add `\` to the end of path. WRONG : `cmake -DPORT="Win" ... ;skia;woff2" "D:"` CORRECT : `cmake -DPORT="Win" ... ;skia;woff2" "D:\"` 2194886 1 ryosei.otaka 2026-03-29 09:40:22 -0700 Pull request: https://github.com/WebKit/WebKit/pull/61627 2194995 2 ews-feeder 2026-03-29 22:17:53 -0700 Committed 310200@main (54dbe2c9f3dc): <https://commits.webkit.org/310200@main> Reviewed commits have been landed.
