The following code raises `clang(implied_comparison_category_type_not_found)`:
```cpp
struct awoo {
friend auto operator<=>(awoo,awoo) = default;
};
```
The following code then raises: `clangd(unused-includes)`:
```cpp
#include <compare>
struct awoo {
friend auto operator<=>(awoo,awoo) = default;
};
```
Not sure how to reproduce on Compiler Explorer.
To fix it, one must use `std::strong_ordering` instead of `auto`.
