I have not used CMake to generate makefile for Qorivva,but you can try to configure its build tool chains as the command line tools in CodeWarrior.
For Classic CodeWarrior, these tools are under:
<CW path>\CW for MPC55xx and MPC56xx 2.x\PowerPC_EABI_Tools\Command_Line_Tools
For Eclipse CodeWarrior, they are under:
<CW path>\CW MCU v10.x\MCU\PA_Tools\Command_Line_Tools
