Additional context
I also tracked other build failures when using MSVC 19.28, while ANGLE depends on a non-standard pow of STL, which is fixed and shipped with VS 19.8. Ironically, this non-standard one was fixed(actually, deleted) by me ;)

C:\Users\Berrysoft\Documents\GitHub\vcpkg could be too long for qt5-webengine which uses deeply nested folders.

ValueError: path is on drive , start on drive C: It must be the same as Neumann said.

Thanks! I moved the vcpkg folder to just C:, and it is still building🤣 I'll report later whether it is success.

[Berrysoft]

It works! Thanks!
