Thanks for the reply David. KSDK_PATH is correct. I believe this was automatic since I started with a clean installation.
But I did find this:
No Rule to Make Target in KDS
It points out that when importing a library, you have to un-check "Copy projects into workspace". If you copy the files into the workspace, the links to other modules don't work.
Having done that, I'm in good shape.
Thanks.
