### Explanation of Changes:
1. **Set C++ Standard**: The key modification is the addition of the following lines:
   ```cmake
   set(CMAKE_CXX_STANDARD 14)
   set(CMAKE_CXX_STANDARD_REQUIRED ON)
   set(CMAKE_CXX_EXTENSIONS OFF)
   ```
   These lines ensure that the project is built using the C++14 standard, which provides the necessary features like `std::enable_if_t`, `std::is_same_v`, and `std::u16string_view`.

2. **Updated `cmake_minimum_required`**: The `cmake_minimum_required` version was updated to 3.10 to align with modern CMake practices and avoid deprecation warnings.

3. **No Other Changes**: The rest of the `CMakeLists.txt` file remains unchanged, as the issue is solely related to the C++ standard.

This change should resolve the compilation errors and allow the build to proceed successfully.
