Support cl.exe (MSVC)

[taljacob2]

Although we use gcc to compile our code,
We should support Windows' cl.exe (i.e. MSVC) compiler too.

Thus, when we export the finaly static library to oop.a file, we should also export it to oop.lib file

So Windows MSVC users could use our library with:

cl.exe main.c oop.lib

To link oop.lib to cl.exe main.c, place oop.lib in the root directory of the project, and add #pragma comment(lib, "Your library name here") to your main.c source code.

For example:

#pragma comment(lib, "oop.lib")

#include <stdio.h>

#include "oop.h"

int main() {
	printf("Hello World\n");

	Object* object = ObjectConstructor("Object");
	object->addIntegerRValueMember(object, PUBLIC, FIELD, "x", 121681);
	object->toString(object);

	return 0;
}

You must place oop.lib in the root folder of the project:
