Hello,
to follow up, this kind of error occurs when you are trying to import to MCUXpresso IDE a SDK package that was generated without MCUXpresso IDE support. The MCUXpresso IDE is usually enabled by default, however, you can double check and change toolchains supported in your SDK package on the Configuration Settings page:

We are also working to improve generated SDK packages so that the error message is clear about missing MCUXpresso IDE support in imported package.
Regards,
Lukas
