build! macro doesn't have the same syntax as use statements

[Awfa]

The build! macro docs say this:

These follow the same convention as Rust use paths.

However, this fails to compile:

windows::build!(
    Windows::Win32::{
        Debug::GetLastError
    }
)

with the following error message:

error: proc macro panicked
  --> src\rust\winapi_wrapper\build.rs:30:5
   |
30 | /     windows::build!(
31 | |         Windows::Win32::{
32 | |             Debug::GetLastError
33 | |         }
34 | |     )
   | |_____^
   |
   = help: message: Could not find namespace `Windows.Win32`

The following does compile however:

windows::build!(
    Windows::Win32::Debug::{
        GetLastError
    }
)

I expect the first one to compile because that's how Rust use paths work.
The error message about not finding the namespace is confusing too.

For context, I ran into this issue when trying to use build! like this:

windows::build!(
    Windows::Win32::{
        Debug::GetLastError,
        Etw::{
            EventRegister,
            EventUnregister,
            EventWrite,
            EVENT_DATA_DESCRIPTOR,
            EVENT_DESCRIPTOR
        },
        ProcessStatus::K32EnumProcesses,
        WindowsProgramming::CloseHandle,
        WindowsEventLog::{
            EvtClose,
            EvtOpenPublisherMetadata,
            EVT_HANDLE
        },
        SystemServices::{
            ERROR_INSUFFICIENT_BUFFER,
            OpenProcess,
            PSTR,
            QueryFullProcessImageNameA,
            TerminateProcess,
        },
    }
)

Glad you found a workaround. Yes, this doesn't work very smoothly today. I'm planning to improve the build parsing soon as the current implementation has a few drawbacks.

This should be fixed as of #773 - let me know if you notice any further issues.
