Compilation issue with CROCO 2.0

Hello,

I tried to compile the latest release (2.0.0) but got the list of errors below. They seem to be related to the newly added GPU implementation. I also saw that Python is now required to compile CROCO. I did have Python3 loaded in my environment, though. I would appreciate it very much if anyone could provide advice on how to properly compile the latest source code.

Many thanks!
