that could be read “…the compiler set…” that is it just doesn’t find “ifx”.

If you type `which ifx` or just `ifx` is the compiler available in the Terminal?

You’re absolutely right. It simply couldn’t find `ifx`. Which is strange considering that cmake starts

```auto
-- The C compiler identification is IntelLLVM 2024.1.0
-- The CXX compiler identification is IntelLLVM 2024.1.0

```

But the problem is mine. Thanks

The wording is confusing. How about:

> Could not find the compiler specified in the environment variable FC:
