Shared library initialization error with Matlab2015b and VS2015

I created a shared library using the following command mex -setup mcc -vg -W -win32 lib:libTest -T link:lib NumberToAlphabet

Program to initialize the shared library below.

if true
  % code
end
class MatLabInit
{
public:
  MatLabInit()
  {
    const char *args[] = { "-nojvm" };
    const int count = sizeof(args) / sizeof(args[0]);
    if (mclInitializeApplication(0, NULL) == false) {
      MessageBox(NULL,_T("Could not initialize the application properly."),_T("Error"), MB_OK);
      return;
    }
    if (libTestInitialize() == false) {
      MessageBox(NULL, _T("Could not initialize libtest."),_T("Error"), MB_OK);
      return;
    }
  }
  ~MatLabInit()
  {
    libTestTerminate();
    mclTerminateApplication();

}

};

It could not initialize the shared library.

Could you please help me solve this.

The error "Could not initialize shared library" commonly occurs when the "MCR_CACHE_ROOT" environment variable is not set.

To set this environment variable from MATLAB use the "setenv" function as follows -

    % sample - setenv('VARIABLE_NAME','VALUE');
    >> setenv('MCR_CACHE_ROOT','C:\TEMP');

For more information related to setting "MCR_CACHE_ROOT" please refer to the link below -

It didn't solve the issue. Initializing shared library still failed.
