I am working on nrf5340 DK using segger embedded studio. Using peripheral_uart example and i added SPI interface code. I need to integrate ICM20948 library to this application. Added all icm20948 related source code in CMakeList.txt ( Inside peripheral uart folder ). But while compiling getting undefined reference to 'sqrt' error. These function actually using in Icm20948DataConverter.c file inside ICM20948 library.
I am attaching modified CMakeList.txt

Pls help me to solve this issue!
Note: SPI is working and ICM20948 library integration also working fine , i am getting all sensor data. Only issue is undefined reference to 'sqrtf' , 'cosf when iam calling some API,s. I think its because of math.h library linking issue. I don't know how to link standard library in CMakeList.txt ,
