I am writing CMakePresets.json for a project which has hundreds of executables.  
(It is a test suite for C++, but that should not be too important.)  
The problem is that I get the following error.

```plaintext
CMake Error: Could not read presets from <project-dir>: Duplicate presets

```

There are many presets, not hundreds but still quite a few.  
Is there a way to get a more detailed message, possibly telling me the names of the duplicates?

I am aware of the `configurationPresets:debug` and its friends but they only seem to work after the CMakePresets.json has been successfully processed.

The latest version in the master branch has greatly improved the error messages.

```plaintext
CMake Error: Could not read presets from C:/Users/me/proj:
Duplicate preset: "cb-foo"
