fix: MSVC error

The error message indicates that the Clang compiler does not recognize the `/utf-8` option, which is a Microsoft Visual C++ (MSVC) specific option. To resolve this issue, you need to conditionally add the `/utf-8` flag only when using the MSVC compiler.

Here's how you can modify your `CMakeLists.txt` to conditionally add the `/utf-8` flag:

1. Check if the compiler is MSVC.
2. If it is, add the `/utf-8` flag.
