Possible duplicate package. Seeking clarification on its handling.

[EZ4Stephen]

I recently noticed that libsigcplusplus and libsigc++ exist as 2 separate packages.

1. Do both need to exist separately?
   -I'm doubtful both need to exist. Currently, libsigcplusplus has support for windows whereas libsigc++ doesn't. They should be the same package after all, so I'm thinking the version of the xmake.lua file for libsigcplusplus should stay.

2. Does xmake currently have support for package aliases?
   -So that if someone tried adding libsigc++ or libsigcpp or libsigcplusplus, they'd all use the same xmake.lua file.
   -If such a feature doesn't exist, could such a feature be added? Or should it strictly be one name for one package?

Don't know about any other packages having this problem, but thought this should be brought up. I'm more focused on adding packages needed for building Ardour, so I haven't looked through the enture list of supported packages across xrepo.
