When configuring examples that communicates with the modem, remember to choose the board type "nrf9160_pca10090ns". This is important, if not it will not compile or work properly.
Cheers, Håkon
the board type is the same as you have mentioned.The build still gives the same errors.
Did you delete the build directory before re-importing the project? That is the path set in the last box ("Build Directory").
This is important, as CMake can cache former set values.
Yes, I tried doing that just now but no success.
What else should I do so that these errors can be removed?
