Issues with the installation

[magicBanana3]

Hello I try to initialize the library, but I'm failing.
I added the librarys in my project-folder, but I get a lot of errors after try one of the examples.
So I tried just to make a connection with this code:

`#ifdef _WIN32
#define _CRT_SECURE_NO_DEPRECATE
#endif

#include "cs104_connection.h"

#include <stdio.h>
#include <stdlib.h>

int main(){
CS104_Connection con = CS104_Connection_create("127.0.0.1", 2404);
}
`

And I get the error: LNK2019 reference to unresolved external symbol "_CS104_Connection_create" in main function.

I don't know why it's not working, because my compile recognize the library.
Maybe I made a mistake in the installation. I also tried to use CMaker, but here I also got some errors. In this case what is exactly meant with the command "make" where should I write it down?
I'm using Visual Studios 2019.

I already thank you for your help!

@magicBanana3 : Did you got your example compiled using VS 2019 ?
