In python3.10, it cannot find elkai v0.1.2. Instead it tries v0.0.9

The other issue is that there is no source distribution for v0.1.2 on PyPI... That's why it's falling back to 0.0.9. I've just been bitten by this on an older Mac (macOS 11.7.3, Python 3.10), for which there is no wheel.

That one should be easy to fix :-)

I can't provide you a wheel for 3.10 and 3.11 using the new manylinux2014 image, because cmake fails with this:

libLKH.a(AddCandidate.c.o):(.bss+0x298): multiple definition of `FirstNode'; CMakeFiles/_elkai.dir/elkai/_elkai.c.o:(.bss+0x2b8): first defined here
libLKH.a(AddCandidate.c.o):(.bss+0x0): multiple definition of `MergeWithTour'; CMakeFiles/_elkai.dir/elkai/_elkai.c.o:(.bss+0x20): first defined here
libLKH.a(AddCandidate.c.o):(.bss+0x8): multiple definition of `BestSubsequentMove'; CMakeFiles/_elkai.dir/elkai/_elkai.c.o:(.bss+0x28): first defined here
...
...
libLKH.a(Best2OptMove.c.o):(.bss+0x138): multiple definition of `CandidateFileName'; CMakeFiles/_elkai.dir/elkai/_elkai.c.o:(.bss+0x158): first defined here

If anybody has time to fix this, I'd be thankful! Seems like elkai.c shouldn't include LKH.h because it generates global symbols that already exist in libLKH.
