PRIVATE / PUBLIC / INTERFACE

+

These modifier control where properties for a given target are visible.

+
    +
  • PRIVATE: Only for the target itself.
    • +
  • PUBLIC: For the target itself and anyone linking against it.
    • +
  • INTERFACE: Only for anyone linking against the target.
    • +
+

The following gives an example for preprocessor definitions specified on a +library target. This behaves in the same way for other properties like for +example include directories.
