MFC C++ static library linked with non MFC console app - c++

Question

I'm trying to compile a console program that uses a static library implementing CString.The console app has been created with the VS wizard with :
Win32 console application with precompiled headers, SDL verification but without ATL or MFC.
The static library is a MFC static library (wizard construction).
Where is (are) my mistake(s) ?
This is what I so long have tried:
I've created a new console app using MFC controls - this compile fine with the static library.
Then I've controlled and modified when necessary every link options, comparing the 2 console projects.
But the 1st console application does not compile.
I'm stucked !
I'm working with Visual Studio 2012 on Windows 10.
Here is the code :
File TestLib.h
#pragma once
#include <atlstr.h>
class TestLib
{
public:
TestLib(){};
TestLib(const CString &tst);
virtual ~TestLib(void);
private:
CString _tst;
};
Fichier TestLib.cpp
#include "stdafx.h"
#include "TestLib.h"
TestLib::TestLib(const CString &tst)
: _tst(tst)
{
}
TestLib::~TestLib(void)
{
}
Fichier ConsoleTest2.cpp
// ConsoleTest2.cpp : définit le point d'entrée pour l'application console.
#include "stdafx.h"
#include "TestLib.h"
int _tmain(int argc, _TCHAR* argv[])
{
TestLib *tst = new TestLib(); // This compile fine !
//TestLib *tst = new TestLib(_T("Test")); // This generates LNK2019 link error
return 0;
}

Here is the solution, thanks to Jochen Arndt
Just have to change the TestLib declaration to
TestLib::TestLib(LPCTSTR str)
: _tst(str)
{
}
