[FEA] Enable CPack for packaging libcudf build

[jdye64]

The option for packaging the current cudf build should be available for end users. This should provide a flag in build.sh to enable the functionality to create a cpack package of a build. Release packages will help greatly once we start integrating with other third party applications that need the headers and share objects without anaconda.
