Fix CMake presets not working with versions older than 3.28

[dijidiji]

Description

Lowered the version in the presets file to 3.

This fixes an issue I had while revising the unit testing guide where a high version number was preventing the presets from being used with older versions of CMake which they'd work with otherwise.

I also renamed the Linux preset to Linux/WSL to make it clear that it can also be used by WSL users, and renamed Windows to Windows (MSYS) to emphasise the difference.

Type of change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

Testing Checklist

The CMake build process runs as before, this just allows presets to be loaded with older versions of CMake (back to 3.21, per documentation)

Checklist

• My code follows the style guidelines of this project
• I have performed a self-review of my own code
• I have commented my code in hard-to-understand areas
• I have made corresponding changes to the documentation
• My changes generate no new warnings
• I have requested a review on the planner board

Summary

The code successfully allows for earlier versions of cmake without inhibiting later versions as well as clears up what can be used with the changes to display names.

Type of Change

The change is allowing earlier versions of cmake to be changed specifically down to version 3.21 according to cmake documentation

Code Readability

The code is clear when read alongside cmake documentation to clear up things such as what versions the version number refers to

Maintainability

This is maintanable as it stays in line with what a cmake preset file is as well as improving it by making it clearer on things such as linux or wsl so people know wsl can be used

Code Simplicity

The code is not unnecasserily long it just does what it has to to fulfill its purpase

Edge Cases

this change enables more versions to be used for cmake so it should make for less problems enabling more people to use it.

Test Thoroughness

Tested with cmake version 4.0.3 and version 3.21 both versions were successful in building the project and tests runned as normal

Backward Compatibility

the code doesnt break modern versions of cmake as tested when version 4.0.3 was used

Performance Considerations

Performance worked well the changes shouldn't effect the performance

Security Concerns

this code doesnt seem to have any security concerns, it does allow for older versions of cmake but from my research i was unable to find any evidence that showed older versions of cmake to 3.21 has any security issues.

Dependencies

There are no new added dependencies.

Documentation

The documentation is simple enough to understand with changes to display names just making things clearer

This PR looks good to me. Lowering the preset schema version to 3 is a sensible fix that restores compatibility with older CMake installations (3.21+), which is important for students using older Linux/WSL environments.

The renaming of the Linux and Windows presets also improves clarity and helps prevent common confusion between WSL, native Linux, and MSYS toolchains. The change is low-risk, maintains full functionality, and aligns with how the presets are actually used.

I have tested with cmake version 4.1.0 and version 3.21 both versions were successful in building the project and the test cases passed successfully.

As a future improvement, it may be worth adding a short comment in the presets file explaining why the version is intentionally kept low, and possibly introducing a shared base preset later to reduce repetition. Overall, this is a solid and student-friendly update
