Error: undefined reference to `softPwmStop': MPU6050 Interfacing with Raspberry Pi

I'm trying to Interface MPU6050 with raspberry pi via simulink. I'm using the following library:

https://in.mathworks.com/matlabcentral/fileexchange/43383-raspberry-pi-mpu6050-sfunction-with-i2c-communication-using-wiringpii2c

and when I build and deploy, I'm getting the following error:

Error executing command "touch -c /home/pi/MATLAB_ws/R2021a/C/Users/Farhan/Documents/MATLAB/Add-Ons/Simulink_Models/Raspberry_Pi_MPU6050_SFunction_with_I2C_Communication_using_WiringPiI2C/MPU6050_Gyro_Accel_ert_rtw/*.*;make -f MPU6050_Gyro_Accel.mk all MATLAB_WORKSPACE="/home/pi/MATLAB_ws/R2021a" -C /home/pi/MATLAB_ws/R2021a/C/Users/Farhan/Documents/MATLAB/Add-Ons/Simulink_Models/Raspberry_Pi_MPU6050_SFunction_with_I2C_Communication_using_WiringPiI2C/MPU6050_Gyro_Accel_ert_rtw".

I'm not sure how to solve this. I have used wiringPi library in raspberry pi. Kindly guide me. Thanks in advance...
