javaaddpath error from c++ shared library

Hello! I created simple function in MATLAB (the name of the func is meshgridC because before it did just meshgrid and when I changed it I forgot to change the name :P)

function  meshgridC(vecX,vecY)
plot(vecX,vecY);
end

So I compiled it to C++ shared library and linked it to Visual Studio 2017.

#include "stdafx.h"
#include "meshgridC.h"

#pragma comment(lib, "libmat.lib")
#pragma comment(lib, "libmx.lib")
#pragma comment(lib, "libmex.lib")
#pragma comment(lib, "libeng.lib")
#pragma comment(lib, "meshgridC.lib")
#pragma comment(lib, "mclmcrrt.lib")

int main()
{
  const int size = 100;
  double x[size] = { 0 };
  double y[size] = { 0 };
  for (int i = 1; i <= 99; i++)
  {
    x[i] = x[i - 1] + 0.01;
    y[i] = x[i] * x[i];
  }

  if (!mclInitializeApplication(NULL, 0))
  {
    fprintf(stderr, "An error occurred while initializing: \n %s ", mclGetLastErrorMessage());
    return -1;
  }

  // Initialize the Vigenere library
  if (!meshgridCInitialize())
  {
    std::cerr << "Could not initialize the library properly."
      << std::endl;
    return -1;
  }
  mwArray rX, rY;
  mwArray vecX, vecY;
  vecX = x;
  vecY = y;
  meshgridC(vecX, vecY);

  meshgridCTerminate();
  mclTerminateApplication();
}

When the program gets to the meshgridCInitialize() function, it fails. It is writing me:

Undefined function or variable 'javaaddpath'
 Could not initialize the library properly.

If I run it from debug, on mclInitializeApplication(NULL, 0) statement, Visual Studio writes me:

Frame not in module
The current stack frame was not found in a loaded module. 
Source cannot be shown for this location.
00000266E9D103B4  mov         eax,dword ptr [rsi]

How can I fix it? Thanks!
