Project Build error

Hi,

I started working on a project and eventually decided to integrate it into version control (perforce). I submit only the folders Config, Content and Source and the .uproject file. When I clone the depot (repository) on the machine where I initially started the project I can build the full project without problems. However, when I clone on my other PC, I get the common error “project could not be compiled, try rebuilding from source manually”. Both systems have the same UE4 version (4.25.4).

Does someone have an idea what could cause this?
Could my project be referencing files outside its own project folder (which consequently are not submitted over perforce)? How would I determine this?

Thanks in advance!
