FRDM-KL25Z project link error Undefined symbol Driver_I2C0

I created a project for my FRDM-KL25Z board.
In "Manage Run-Time Environment", I added I2C using CMSIS Driver | I2C | Multi-Slave.
My app code includes "Driver_I2C.h".
My code compiles, but I get a linker error:

Error: L6218E: Undefined symbol Driver_I2C0 (referred from i2c_multislave.o).

See details below.

I guess Driver_I2C0 is declared in a library that is missing from my project.

Can somebody point me to some uVision docs that would help me correct the problem?
