Centos 7 Zeroc Ice Python 3 Builder

Builds Zeroc Ice wheel for CentOS 7 using SCL Python 3.8.

This can be used to create installable binary packages as an alternative to compiling from source using pip.

docker build -t builder .
docker run --rm -v $PWD/dist:/dist builder

To build a different version of IcePy:

docker run --rm -v $PWD/dist:/dist builder /build.sh VERSION

Packages will be copied to $PWD/dist.
