What is the Working Directory During Configure?

### Brief Issue Summary

I have a CMake script that sets my project's version using `execute_process` and a call to Git. My build directory is within the repo (`${workspaceFolder}/build$). The script works fine if I run `cmake` on the command-line. When I configure via the CMake Tools, the script fails with:

```
[cmake] fatal: not a git repository (or any of the parent directories): .git
[cmake] CMake Warning at cmake/GitVersion.cmake:6 (message):
[cmake] Git failed (not a repo, or no tags).
```

Suggesting that CMake is not being run from either the Workspace directory or the build directory.

### Expected:

1. CMake Tools runs CMake somewhere within my repo

### Apparent Behavior:

1. CMake Tools runs CMake from a different directory

### Platform and Versions

- **Operating System**: macOS
- **CMake Version**: 3.19.3
- **VSCode Version**: 1.54.3
- **CMake Tools Extension Version**: 1.6.0
- **Compiler/Toolchain**: Apple Clang

### Other Notes/Information

I looked but I couldn't see a setting for the working directory?

Begin by reproducing the configure flow described in the issue, using the cmake/GitVersion.cmake script and its execute_process call to observe the working directory. Trace the CMake Tools configure entry point to determine where CMake starts, then verify the result with the same Git error. Done means the working-directory behavior is corrected or clearly exposed as a setting, with the reported in-repository configuration working.
