CCS/IWR1642: Cannot import the mmwave demo project into CCS

Tool/software: Code Composer Studio

Am trying to the most basic thing to get the mmwave demo to build and the crappy TI dev tools are giving me a rake in the face.

I simply want to import the demo project for the IWR1642 from the TIREX into my workspace and have it build.

I have CCS V8 and just installed the mwave SDK 3.1.0.2

I have used CCS and the simplelink_cc13x0 SDK on this same system with minimal issues (all issues I have had were caused by poor TI documentation or dev tool problems).

I have set my dev board in setenv.sh to IRW1642 and the sourced setenv.sh

Then I ran ccstudio to go into code composer which the way I understand what I read should give CCS the right environment?

Then to load the mmwave demo project into CCS:

In TIREX it shows a folder saying mmWave Sensors -> Industrial Toolbox 3.1.1 -> Labs -> mmWave SDK Demo ->16xx mmWave ...

I import this into CCS

I get 5 errors on import saying similar but first is

COM_TI_MMWAVE_SDK_INSTALL_DIR/packages/ti/demo/xwr16xx/mmw/mss/mss_main.c cannot be resolved

other 4 are similar including the project config mss_mmw.cfg

Of course it refuses to build as there is not even a project config

What is going on here and how do I get the basic demo project to load into CCS and build properly?
