I am not sure how vcpkg builds ODB (or which version), but the first
thing to try would be to add `--std c++11` to your ODB compiler
invocation and see if that helps.

If that doesn't help, you can try to get ODB via build2[1], which is
known to build the runtimes[2] in the C++20 mode with Visual Studio
2022.
