All,
This is not an issue triggered because of the difference in tool versions. ISDK heavily depends on the environment variable IA_SDK_HOME, and all library/header files are linked depending on it. You probably checked the option "Copy to Workspace" while importing, messing up the file structure. The project should build as is, no need to include other components(NSP for example)
Also, please find the software requirements here
Regards,
Vinesh
