Everything works fine, so I can compile and run the code.
But Qt creator show me semantic issue (see in the picture):

use of undeclared identifier blockDim, blockIdx and threadIdx

although the compile was successful.

It looks like indexer or I don't know issues.
Please can you help me how to remove this "cometics" problem.
Thank you
