Build error in standalone Python wrappers

[lamyj]

The discrepancy between using setup.py and cmake is a bit weird: compiling with cmake should cause the same error as with setup.py. Do you have still have the cmake output?

Anyhow, the latest commits have added an extra dependency to xsimd to get SIMD operations on all EPG models, yielding quite a large speedup. I have not yet updated the README for this, but xsimd is rather simple to install: you can follow their instructions (basically clone and follow the usual cmake route), or run what I'm using in the macOS CI (https://github.com/lamyj/sycomore/blob/master/.ci/brew/install#L33-L37) from the root directory of sycomore.

All the off-resonance stuff is a bit experimental. If you have some examples to validate the results, I'll be glad to have a look at them.

This is the output after executing cmake and make from the build directory:

It seems good. I have already installed the xsimd dependency, but I tried again with your instructions. I obtain the same error when I try to run the setup.py.

Yes, If I will be able to build the library, I will surely share our results. And we will eventually help with the testing of this experimental implementation.

Latest commit (154096b) should solve this issue with setup.py. Can you retry and confirm?

[GiadaFallo]

Yes, it's working!
