[INTERNAL] [FIXED] - Corrected invalid escape character in CMake path handling

Pull Request resolved: #47641

Test Plan:
To test the changes, I performed the following steps:

1. Cloned the repository and checked out the `fix-cmake-invalid-escape-character` branch.
2. Ran the CMake build on a Windows environment where the issue was previously occurring.
3. Verified that the build process completed successfully without the "invalid character escape" error.
4. Ensured that the path handling now works correctly in CMake on Windows platforms.
