How are you importing the project ?
Assuming the project was created using the same version of ISSM/QMSI you should be able to import it using the ... 'Existing code as a Makefile project'
If this is not working for you a workaround would be to create a new project with the Platform/Kernel settings you need.
Use one of the provided tempates and name it with the name of the project you are importing.
Then just drop the files from the project you are importing into that projects directory the workspace and select F5 in the IDE to refresh.
