[bug] Failed to use CMake installed on MSYS2 and Cygwin.

@paulmaybee is already working on this.

Since Dec 10, 2024.

### Brief Issue Summary

Based on what CMake Team said in this [topic](https://discourse.cmake.org/t/how-to-check-that-the-current-compiler-is-gcc-msys-when-using-ninja-generator/6698/7?u=hwhsu1231) of CMake Discourse, we should use the CMake installed on MSYS2 and Cygwin when targeting Cygwin’s or MSYS2’s runtime environments. For example:

- we should use `C:\msys64\usr\bin\cmake.exe`
- instead of `C:\Program Files\CMake\bin\cmake.exe`

> If the target platform is `Windows`, regardless of whether the target ABI is GNU-style (MinGW) or MSVC-style, then the `C:\Program Files\CMake\bin\cmake.exe` tool should work. It’s only when targeting cygwin’s or msys2’s runtime environments that one needs a CMake built for them, and such a CMake won’t work for targeting Windows. These platforms are all independent of each other and tooling cannot be mixed among them.

However, there are **SOME** problems when configuring with CMake Tools.

### Environments and Versions

- OS version: **Windows 11**
- Compiler version: **GCC 11.3.0**
- CMake version: **CMake 3.23.2**
- CMake Tools version: **1.13.21**
