I’ll leave this here as a note-to-self and for anyone else bumping into the same rock:

In order to build a MVS2022 project that can switch between classic or LLVM compilers (assuming \<= oneAPI2023), one can now do it with CMake (version \>3.29, I’m testing with 3.30.2):

- Classic C++ and Classic Fortran  
`-DCMAKE_GENERATOR_TOOLSET=Intel C++ Compiler 19.2,fortran=ifort`
- LLVM C++ and LLVM Fortran  
`-DCMAKE_GENERATOR_TOOLSET=Intel C++ Compiler 2023,fortran=ifx`

The Visual project is well set, and one can also then manually revert/change the compiler for individual projects.
