Create a static class function that takes an infinite number of arguments

Question

I am trying to create a function that takes an arbitary number of strings and then outputs them all on a single line. I want this function to be a static member function of my Utils class.

Utils::output("I","am","a","sentence"); // --console-output--> I am a sentence

Here's what I've attempted:

Utils.h:

class Utils{
public:
    template<typename First, typename ... Strings>
    static void output(First arg, const Strings&... rest);
};

Utils.cpp:

void Utils::output() {
    std::cout<<std::endl;
}

template<typename First, typename ... Strings>
void Utils::output(First arg, const Strings&... rest){
    std::cout<<arg<<" ";
    outputs(rest...);
}

main.cpp:

int main() {
    Utils::output("I","am","a","sentence");
    return 0;
}

My project is currently not even compiling! I am getting this error:

error LNK2019: unresolved external symbol "public: static void __cdecl Utils::output<char const *,char [3],char [2],char [9]>( referenced in function _main First.exe : fatal error LNK1120: 1 unresolved externals
