EXTERNAL_INCLUDE env variable is not imported from VS dev environment

[equeim]

Brief Issue Summary

Running C:\Program Files\Microsoft Visual Studio\2022\Community\Common7\Tools\Launch-VsDevShell.ps1 script in PowerShell sets, among others, a EXTERNAL_INCLUDE environment variable with this (example) value:

C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.42.34433\include;C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.42.34433\ATLMFC\include;C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\VS\include;C:\Program Files (x86)\Windows Kits\10\include\10.0.26100.0\ucrt;C:\Program Files (x86)\Windows Kits\10\include\10.0.26100.0\um;C:\Program Files (x86)\Windows Kits\10\include\10.0.26100.0\shared;C:\Program Files (x86)\Windows Kits\10\include\10.0.26100.0\winrt;C:\Program Files (x86)\Windows Kits\10\include\10.0.26100.0\cppwinrt

This env variable is (I assume) used by MSVC as an alternative to /external:I option (https://learn.microsoft.com/en-us/cpp/build/reference/external-external-headers-diagnostics).

However this extension does not import it, which results in unnecessary compilation warnings from external headers that should be hidden by default (#4215).

[Yingzi1234]

@equeim Thanks for your github question! In order to better reproduce your problem and fix it, could you give us a detailed reproduction step-by-step and some additional information?

[equeim]

Sure.

1. Download minimal example project: warnings-test.zip
2. Open it in VSCode
3. Build it

Expected result:
During CMake configuration it outputs something like:

EXTERNAL_INCLUDE environment variable is C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.42.34433\include;C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.42.34433\ATLMFC\include;C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\VS\include;C:\Program Files (x86)\Windows Kits\10\include\10.0.26100.0\ucrt;C:\Program Files (x86)\Windows Kits\10\\include\10.0.26100.0\\um;C:\Program Files (x86)\Windows Kits\10\\include\10.0.26100.0\\shared;C:\Program Files (x86)\Windows Kits\10\\include\10.0.26100.0\\winrt;C:\Program Files (x86)\Windows Kits\10\\include\10.0.26100.0\\cppwinrt

During build there are no warnings.

Actual result:
During CMake configuration it outputs "EXTERNAL_INCLUDE environment variable is not set".
During build there are C4365 warnings:

[build] C:\Program Files (x86)\Windows Kits\10\include\10.0.26100.0\cppwinrt\winrt/base.h(174): warning C4365: 'return': conversion from 'int' to 'uint16_t', signed/unsigned mismatch

When building this project in command line inside VS developer environment the behaviour matches one in "Expected result".
