If the build fails with C++11/C++17 compatibility errors like the following, the issue is that the build system is defaulting to an older C++ standard:
```text
[...] error: 'constexpr' is not a type
[...] error: expected ';' before 'constexpr'
[...] error: 'constexpr' does not name a type
```
**Solution**: Your compiler might be using an older C++ standard. Edit `cmake/cpu_extension.cmake` and add `set(CMAKE_CXX_STANDARD 17)` before `set(CMAKE_CXX_STANDARD_REQUIRED ON)`.
To check your compiler's C++ standard support:
```bash
clang++ -std=c++17 -pedantic -dM -E -x c++ /dev/null | grep __cplusplus
```
On Apple Clang 16 you should see: `#define __cplusplus 201703L`
