Currently I don't think you can override a builtin target like "package".
What you can do is:

Do not include(CPack) but generate the CPackSourceConfig.cmake
in another way. If this file exists in the build tree the CMake generator
should "generate" a package_source target as usual.

Then define your own "package"  custom target.

Another way around is to define your own package and package_source
using custom command (which may call CPack with hand-crafted  config file).
