CMakePresets fail to load on RedHat. Error on Output: Invalid variable reference ${which_declare}

[pilarArr]

Brief Issue Summary

Issue Related to #1841

I'm not able to produce an example repo.
But I'll try to layout a MWE.
Since it's the presets loading that fails. I don't think the rest of the project does matter.

My project layout would be somethin like this

(root)
├── CMakePresets.json
├── CMakeLists.txt
├── scr
│   ├── hello_world.c
├── include
│   ├── hello_world.h

This would be my CMakePresets.json file:

Tested the vsix provided on #3959 (comment) and it does not solve the problem. Same error.

[gcampbell-msft]

@pilarArr I'm curious if you have some answers that might help investigate.

Where is this ${which_declare} defined? Is it defined as an environment variable itself?

[pilarArr]

@gcampbell-msft I found these mentions to which_declare on the env,
but I haven't touched that, I believe that is just how it is out of the box.

BASH_FUNC_which%%=() {  ( alias;
 eval ${which_declare} ) | /usr/bin/which --tty-only --read-alias --read-functions --show-tilde --show-dot "$@"
}
which_declare=typeset -f

[gcampbell-msft]

Is this defined in the environment variables for the linux installs?

[pilarArr]

that would be the default environment on login

@pilarArr Based on the file information you provided for CMakePresets.json, we are unable to surface your issue on Linux platform and we can Configure success. In order to better solve your problem, could you provide me your reproduction file and reproduction steps? Thank you in advance!
