Level 2 Matlab S-function gives error while code generation

I am trying to use a Level 2 Matlab S-funtcion with the below code. There is no problem when I use it in normal mode but when I try to use it in external mode and build the code it says

"The corresponding 'CursOut.tlc' file for the MATLAB S-function 'CursOut' in block 'JustOut/Level-2 MATLAB S-Function' must be located in the current working directory, the MATLAB S-function directory 'C:\Users\generic\Desktop\RT\JustOut', or the directory 'C:\Users\generic\Desktop\RT\JustOut\tlc_c'"

My code is as below. Can anyone help? Thank you.

function CursOut(block)
setup(block);

function setup(block)

block.NumInputPorts  = 0;
block.NumOutputPorts = 1;
block.SetPreCompOutPortInfoToDynamic;

block.OutputPort(1).Dimensions  = 1;
block.OutputPort(1).DatatypeID  = 0; 
block.OutputPort(1).Complexity  = 'Real';
block.OutputPort(1).SamplingMode = 'sample';

block.NumDialogPrms     = 1;
block.RegBlockMethod('Outputs', @Outputs);   
block.RegBlockMethod('Terminate', @Terminate);

function Outputs(block)
coords = get(0,'PointerLocation');
block.OutputPort(1).Data = coords(1);

function Terminate(block)

Simulink cannot generate code from a MATLAB S-function unless you write a TLC file to inline it. See Inline MATLAB File S-Functions.
