cpp command line argument library

Cpcli (Beta)

serdepp base command line parser

Example

#include "cpcli/cpcli.hpp"
#include <serdepp/adaptor/nlohmann_json.hpp>
#include <serdepp/adaptor/fmt.hpp>

enum class O {
    one, two, three

    }
};

    static void execute(cpcli::Command &cmd) {
        auto map = serde::deserialize<Test>(cmd);
        fmt::print("{}\n",map);
    }
};

int main(int argc, char *argv[])
{
