While practicing compiling cpp into dll, I encountered the following problem

My Window bit is 64

Here is cpp code that compiled:

#include <iostream>

extern "C" {
    __declspec(dllexport) int firstDll(int coercivity) {
        return 1 + coercivity;
    }
}

Compile command is:
g++ -shared -o Te.dll Te.cpp

And I drop Te.dll into DependenciesGui, and I found out that there was no dependencies:
ext-ms-win-oobe-query-l1-1-0.dll

I think my cpp code is very simple, Cannot understand there is no required dll

How can I solve this problem?
Should I download that dll?
Please Help.
