running ctest using test explore with env vars from test presets

[mikirothman]

Brief Issue Summary

hello
our test presets have bunch of environment variables (composed by conan due to our dependency graph) which we need in order to launch the tests,
we were expecting to see those vars along the ctest command.
but the command ctest invokes is:

ctest.exe -T test --output-on-failure --build-config Debug -R ^MyProj\.MyTest$

Due to the missing env vars the tests fail when running from the test explorer.
Running ctest —preset ${my-preset} from the terminal pass the env vars to my test executables

@mikirothman Thank you for your github issue! To be able to reproduce your question better, can you help us answer the following question?

1. How do you run CTest?
   Did you run the test through VSCode's CTest Explorer or did you run the CTest command manually?
   If VSCode, please confirm how VSCode invokes ctest? (e.g., did it use the CTest: Run Tests button?)
   If running manually, please provide the full command and terminal output. 2.
2. how are your CMake presets (CMakePresets.json) defined?
   Could you share CMakePresets.json or the relevant CTest preset section?
   (especially the environment field to see if the environment variables are actually defined in the preset)

1. How do you run CTest?
   We tried with vscode, both with Run CTest button from the Status bar and from the test explorer.
   we doubled checked that the active preset is configured properly with the desired preset.
   when running manually, everything works as expected.

2. how are your CMake presets (CMakePresets.json) defined?
   Not sure I understand the question; they are defined according to docs.
   we have several environment variables defined in the preset, which are missing from the test executables when running from vscode.
   the fact that running from command line with the desired preset is kinda of a proof that the issue is not at the preset side.

@mikirothman @gcampbell-msft We can reproduce this issue on latest version CMake Tools1.21.2(pre-release), you can get the details below. Thank you!

Environment:
Linux: Ubuntu 22.04.4LTS

Repro steps:

1. Download this folder ctest_env_test.tar.gz and open it with VSCode
2. Click F1 to run command CMake: configure
3. Open terminal window and run below code

cmake --preset default
ctest --preset default

4. Check if can be run successfully
5. Open the Testing page and click on the Run Test button of Myproj.MyTest line
6. Check if can be run successfully

Actual result:
Running CTest manually works, but running it inside VSCode fails
