C++ mangle names in dll and in using this dll project don't matched

Question

I'm trying to use some lib and dll in my Visual C++ (2015, OS - Windows8x64) MFC Win32 project. This lib is old, from 2005. And in my project I recieve unresolved external symbol errors on some dll's functions calling. So I made a little dumpbin on the referenced dll and it turned out that the mangle names do not match. For example these functions. In *.h file:

1.

class AFX_EXT_CLASS CDcmPatientModule : public CDcmModule
{
public:
    DECLARE_SERIAL( CDcmPatientModule );
public:
    CString& PatientName();
......
}

and

2.

class  AFX_EXT_CLASS CDcmIOD : public CObject
{
    friend CDcmModule;
public:
    DECLARE_SERIAL( CDcmIOD );
    void Export( const CString& pathname );
    .....
};

1. Mangle name in project

?PatientName@CDcmPatientModule@@QAEAAV?$CStringT@DV?$StrTraitMFC@DV?$ChTraitsCRT@D@ATL@@@@@ATL@@XZ

Mangle name in dll

?PatientName@CDcmPatientIdentificationModule@@QAEAAVCString@@XZ

demangle name in project (undname command) is:

public: class ATL:CStringT<char,class StrTraitMFC_DLL<char,class ATL::ChTraitsCRT > > & __thiscall CDcmPatientIdentificatioModule::PatientName(void)

demangle name in dll is:

public: class CString & __thiscall CDcmPatientIdentificatioModule::PatientName(void)

2. Mangle name in project

?Export@CDcmIOD@@QAEXABV?$CStringT@DV?$StrTraitMFC@DV?$ChTraitsCRT@D@ATL@@@@@ATL@@@Z

Mangle name in dll

?Export@CDcmAttributeSet@@QAEXABVCString@@@Z

demangle name in project

public void __thiscall CDcmIOD::Export(class ATL::CStringT<char,class StrTraitMFC<char,class ATL::ChTraitsCRT<char>>>const &)

And demangle name in DLL

public: void __thiscall CDcmAttributeSet::Export(class CString const &)

So as you can see the difference is between "CString" How to make these names matched??

Added #define USE_ADS_SHARED_LIB - nothing is changed Adding __stdcall in function's declaration also didn't help.
