Compilation error when using lambda to subscribe to a signal in sigslot

[2stLv]

I want to replace boost signals2 with sigslot. But code that does not report an error using boost signals2 will report an error using sigslot.
`enum class EventType : uint32_t
{
_1,
};

class CBaseData
{
public:
CBaseData()
{
}
virtual ~CBaseData()
{
}

public:
private:
};

using tPublisherSignal = sigslot::signal< void( EventType ,const CBaseData &)>;
using tPublisherConnect = sigslot::connection;

tPublisherSignal mSig;

tPublisherConnect subscribeEvent(const std::function<void(EventType, const CBaseData &)> &subscriber) {
return mSig.connect(subscriber);
}

int main() {
subscribeEvent([](EventType, const CBaseData &) {
//std::cout << typeid(CBaseData).name() << std::endl;
});
}`

BUILD info:

Can you try changing subscribeEvent(const std::function<> &) to subscribeEvent(std::function<>)?

don`t work ,same error
