Hi @vkucera I am commiting my code first time. I also checked my errors and I see it is only showing in the CMakeList.txt. Could you please look into it?

@orubza Your PR does not even compile. You are supposed to test it locally.

Dear @orubza, could you please check your PR locally? There are several errors. Please commit only after your code compiles successfully.

I have tested the code locally multiple times, and also done a fresh ninja build, and it compiles and runs successfully on my machine. I have attached the screenshot of my ninja build.

@orubza

• Your screenshot shows compilation of an MM tutorial task, not of the code in this PR.
• Your branch is 417 commits behind the upstream, so you cannot possibly be testing your code with the latest O2Physics.
• You are adding two files with names differing only in capitalisation. This will break the repository for all macOS users.

Please pay attention to what you do and test your changes properly.
