CMake 3 on aarch64, ppc64le and s390x

[ax3l]

Hi,

can we add a recent CMake to the ppc64le, aarch64 and s390x images?
While PyPI provides usable binary wheels for i686 and x86-64, these less popular architectures currently have to build a recent CMake 3 from scatch.

Hi, it'll probably benefit more people to ask for new wheels to be built over at https://github.com/scikit-build/cmake-python-distributions (e.g. scikit-build/cmake-python-distributions#96) rather than only supplying this in a manylinux image no ?

Yep, already following those, thanks! That would probably work if e.g. scikit-build/cmake-python-distributions#96 considers switching the CD framework for something like cibuildwheel.

But on the other hand it makes sense to me to add a modern build system generator together with the modern C/C++ compilers in the manylinux images.
