@amadio, it seems that if I configure with -Dbuiltin_veccore we don't get builtin_vc on, thus VECCORE_ENABLE_VC macro doesn't expanded. In turn, this leads in not being able to compile Math_vectypes.hxx.

@xvallspl and I were discussing and we can diagnose this either in the cxx file or here. Alternatively, we should just enable builtin_vc, saving time and efforts :)

I made it such that builtin_veccore forces builtin_vc to be ON if vc is ON. However, it should be possible to use VecCore without Vc (that's the whole point of having VecCore), so I'm against forcing Vc and VecCore to be locked to be the same, or we will never be able to change the backend later to be either Scalar or UME::SIMD. The macro VECCORE_ENABLE_VC is in ${VecCore_DEFINITIONS} when the Vc backend is enabled, so targets should rely on that rather than turning it on by hand.

Concerning ${VecCore_DEFINITIONS} I just committed a change to hide this inside Math_vectypes.h otherwise is unworkable. It means that enybody including a ROOT Math header will need to define VECCORE_ENABLE_VC of ROOT was built with Vc and VecCore enabled.

Hi @peremato, I saw the commit and agree with you that everybody having to define it is not optimal, but the current solution is not great either, because it only works when both VecCore and Vc are enabled. We will need to fix it later to be able to use at least the UME::SIMD backend, which works much better on KNL. At some point, we should require that new developments work with both UME::SIMD and Vc, otherwise there is no point in not just using Vc directly. I think that using ${VecCore_DEFINITIONS} in combination with #cmakedefine to create a configuration header is the way to go in this case.
