[BUILD] Fix cpack broken package version

[jafonso]

Changes

At the moment, when I follow the instructions for generating binary packages (link), I can create a rpm with the correct name, but it has the wrong version configured (e.g. 0.1.1 instead of 1.12.0):

$ rpm -qip opentelemetry-cpp-1.12.0-centos-7-x86_64.rpm
Name        : opentelemetry-cpp
