Simulink model build fail with 'Function TAR tried to add two files as "types_c.h".'

Hello, I am trying to build a simulink model using Raspberry Pi 3 model B for face detection.

I am referring to the model here:

https://www.mathworks.com/help/vision/examples/detect-and-track-face.html

I replace the video input to V4L2 video capture from raspberry pi.

But when I run the model, I have the error

### Creating data type transition file rasp_complicated_dt.h
### File v4l2_capture.c associated with S-Function 'v4l2_video_capture_sfcn' (used in 'rasp_complicated/V4L2 Video Capture') does not exist
.### Evaluating PostCodeGenCommand specified in the model
### Using toolchain: GNU GCC Raspberry Pi v1.0 | gmake (64-bit Windows)
### 'C:\Users\Asus\Documents\reference for fyp\streamingFaceRecognitionV2.1\rasp_complicated_ert_rtw\rasp_complicated.mk' is up to date
### Building 'rasp_complicated': make  -f rasp_complicated.mk all
### Build procedure for model: 'rasp_complicated' aborted due to an error.
Function TAR tried to add two files as "types_c.h".

and it fail to run the model on my Raspberry Pi. Any idea what cause the problem?

I think I know why. Code generation is not supported for vision.CascadeObjectDetector in Simulink.
