Hello, I'm running into this issue when compiling a Genred for the CPU backend. I assume it's a simple environment issue. I have g++ installed (as well as build-essential etc.).
How can I make sure that KeOps can find the compiler? Is there a good way to make this portable and search as widely as possible on unknown systems as well?
