If you try to build WebKit at the root of the drive, you cannot build. e.g. If you checkout WebKit/WebKit at `D:\` and you try to build using `perl Tools\Scripts\build-webkit --release` command, build-webkit runs `cmake -DPORT="Win" ... ;skia;woff2" "D:"`. build-webkit uses `D:` to mean `D:\`. 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:\"`
