MINSIGSTKSZ error happens in Ubuntu 22.04

Error

Once I build ROBIN on Ubuntu 22.04, the below error occurs:

How to resolve

According to this solution, when I add the following two lines:

#undef MINSIGSTKSZ
#define MINSIGSTKSZ 16384

like this:

// at line 10821 of `tests/catch.hpp`
#undef MINSIGSTKSZ
#define MINSIGSTKSZ 16384
namespace Catch {

    struct SignalDefs {
        int id;
        const char* name;
    };

    // 32kb for the alternate stack seems to be sufficient. However, this value
    // is experimentally determined, so that's not guaranteed.
    static constexpr std::size_t sigStackSize = 32768 >= MINSIGSTKSZ ? 32768 : MINSIGSTKSZ;

it can be resolved.

Point to discuss

I heard that the value might differ depending on the OS. What would be the best way to handle this?
