Netbeans:如何包含其他 C++ 静态库项目?

I managed to create a Sign.h and Sign.cpp containing a working class Sign. I added these to a Console Project and it works great:

  #include <iostream>
  #include <ostream>
  #include "Sign.h"

  int main()
  {
      Sign sign = Sign::parse("b");
      std::cout << sign.toString() << " " << sign.getValue() <<"
";
  }

但是，我想创建一个包含 Sign 类的静态库，所以我创建了一个静态库并添加了 Sign.cpp 和 Sign.h 到它.现在的问题是，我似乎无法将 Sign 类包含在主控制台程序中.
