Environment Variables Ignored in 0.11.0

Brief Issue Summary

Environment variables defined in project settings.json are ignored.

Expected:

Previous versions of CMake Tools were using the cmake.environment variable set in my project settings.json file.

Apparent Behavior:

CMake is completely ignoring those environment variables. It tries to compile the test program but fails to find a linker.

Other Notes/Information

Documentation says to leave environment variables in settings.json…so what do?

@vector-of-bool thank you for the update, this fixed my issue! I’ll deal with the CMake server thing later.

[vector-of-bool]

I was able to reproduce and fix the issue. It was a silly mistake with a hole in the TS type-checker. I found that the issue only occurs when using non-cmake-server mode. The legacy driver wasn’t receiving the environment variables from configuration.

The issue you’re seeing when you enable CMake Server is another issue. If I were you, I’d do some investigation and maybe open another issue for it.
