Notification Example can't be build

Hello all, nice to meet you!
I have the following problem with one of your examples from the following link:
PLCnext/CppExamples: Collection of various C++ sample code for PLCnext Technology controllers. (github.com)The example is for Notification Example.
I get and follow the descriptions in readme file as a part from Notification example folder. I got to the following execution:

plcncli generate all
plcncli build

When I run them I get the following errors :
Is there some workaround about them, and how I can resolve them ?
Thanks in advance!
