Intellisense fails to find system headers in 1.20.5 (possible cmake integration issue?) #12293
Description
Environment
- OS and Version: Win 10 64bit 19045
- VS Code Version: 1.89.1
- C/C++ Extension Version: 1.20.5
Bug Summary and Steps to Reproduce
Bug Summary:
When updating to version 1.20.5, intellisense no longer finds system headers (eg, the entire standard library, windows.h, gl/GL.h). The project still builds correctly, but every system header is flagged as an error. Browse functionality to those headers is similarly broken.
Even manually specifying those paths with C_Cpp.default.includePath does not work.
This did work in 1.19.9, and does again after a rollback. Testing a re-upgrade to 1.20.5 breaks again. Clean/etc does not help.
This occurs with multiple cmake-based projects. Nothing relating to cmake or its extensions have updated recently, and I am unaware of a setting to change to affect this.
Steps to reproduce:
- Open a C++ project that includes any standard library header, using v1.19.9. Note that intellisense and browse work.
- Upgrade the extension to 1.20.5, reload extensions.
- Note that every standard library or system header is now unable to found, breaking all intellisense and browse functionality.
Expected behavior:
Intellisense and browse would be able to find system libraries that are used during compile, and not flag them as errors.
Configuration and Logs
Note that this c_cpp_properties.json was generated specifically for this question; I usually don't have one in the workspace. Whether it is present or absent does not affect this issue.

There is no "C/C++: Log Diagnostics" command; there is one for cmake. That provides:
