Include ncurses with rr release on linux

[Karrenbelt]

I setup an empty virtual environment using python3.7 and installed libroadrunner, but I get an error on import. I'm using Ubuntu 19.10

Hi @Karrenbelt,

this is a common error I see on clean linux machines. Roadrunner requires the libncurses library installed on the system. This is not packaged as part of libroadrunner. Installing libncurses will solve the issue. See for instance https://www.cyberciti.biz/faq/linux-install-ncurses-library-headers-on-debian-ubuntu-centos-fedora/

@hsauro @luciansmith Any chance this can be packaged with roadrunner? Often users do not have admin rights on workstations so installing a system library can be problematic whereas a pip install normally works in user space.

Yes agree, we heard about his also from another group this morning.

Changed the issue: we should see if we can include ncurses with the linux release (perhaps by statically linking it?)
