Postfix to append to the target file name for configuration <CONFIG>.
When building with configuration <CONFIG> the value of this property is appended to the target file name built on disk. For non-executable targets, this property is initialized by the value of the variable CMAKE_<CONFIG>_POSTFIX if it is set when a target is created. This property is ignored on the Mac for Frameworks and App Bundles.
