Including blosc2 shared libs in tables wheels

[FrancescAlted]

After my (failed) attempts to include the blosc2 shared libraries in the wheels (see latest commits in master), I am wondering if somebody more knowledgeable than me could give me a hand.

Locally, the tables package works well as the Blosc2 libraries are copied to tables directory, but including them inside wheels is a whole another story. Anyone @avalentino @matham ?

Sorry, I'm not an expert in this field.
In principle cibuildwheel, among other things, should address all the stuff related to shared libraries, but apparently it is not the case.
I will try to investigate.

I'll take a look when I get a chance. I'm not familiar with blosc in pytables, is there a simple way to test whether blosc2 is working properly? Would tb.which_lib_version("blosc2") do the trick?

Thanks @matham . Yes, tb.which_lib_version() should do the trick. FWIW, I have been able to correctly fixing wheels by copying blosc2 shared libs to /tmp/hdf5/lib. Agreed, this is kind of a hack, but at least it works! Now I am trying to fix the loose ends in CI.
