CMake issue since #913

[jvdp1]

Description

Since #913, I get the following error with CMake. Any idea what the problem is.

Expected Behaviour

It should compile with CMake

Version of stdlib

master

Platform and Architecture

Linux (Fedora) + Intel OneAPI + Cmake 3.31.1

Additional Information

No response

The issue is that the directory blas is not created by cmake, and therefore, fypp fails to create the F90 files.
