SES NCS seem to build ok but throws "Error starting process echo"

[Smart.Enrg]

Hi

When I try to build NCS sample using SES (v5.40, also v5.30a nordic edition) it seems to build the project correctly (.elf, hex are generated) 
But it throws error at the very end (screenshot attached) "Error starting process echo".

What's the significance of this and how to resolve this issue? Please advise.

This is an issue in the OpenThread CMakeLists.txt file, that relies on Linux echo command.

I've made a PR to the OpenThread project here: github.com/.../6175

Thanks Torsten,
I can build OpenThread projects error free now, with following steps: 
Clean solution
close SES
relaunch SES
Run Cmake
Build
