Download error during build

I may be wrong, but I think that one of the target download is no longer valid:

Hello,

Thanks for reporting the issue and trying out SimpleITKPythonPackaging.

This error message indicates that your cmake does not support HTTPS. As CMake appears to be in "/usr/local", I'll assume that you built CMake yourself. You need to set "CMAKE_USE_OPENSSL" to true when building CMake.

Alternatively, you could install CMake in you Python environment with "pip install CMake".

Thank you very much for your help, and sorry for the silly question!

I will add this issue to the FAQ as it has come up a couple times and it's not clear what the underlying problem is.

On linux, you could simply run:

./scripts/dockcross-manylinux-build-wheels.sh
