Hi Cristian,

thanks for reply. I also went the manylinux2014 path now and got the
extension to be manylinux2014 compatible except for the QT dependencies
(which are resolved by PySide2 and shiboken2 in the end). One potential
issue is llvm, which I currently bypass by using an up to date linux to
generate the binding cpp/h files. It looks like PySide2 might already be
compatible to manylinux2014 which is CentOS 7 based (but that's just a
guess from unexperienced me with these matters).

While digging into this I also learned about this PEP which has been
accepted for the future (following manylinux2014):
