pkgname_ADDED shows if the package is added in a iteration of CPMAddPackage (or CPMFindPackage) of the same package and currently works in next way:

• if first iteration:
  • if local : pkgname_ADDED STREQUAL ""
  • if downloaded: pkgname_ADDED STREQUAL "YES"
• if second or any later iteration:
  • pkgname_ADDED STREQUAL "NO"

This can be useful. Though, I need to understand in later iterations if the package is local or not.

I propose to add pkgname_LOCAL variable.
