Just checked today the IntroJucer, see how it could replace our custom tool and plugin wrapper.
Looks like there is no script to build the folder stuff of AAX on Windows.
Would it make sense to add something a bit like that this to the build system ?
CALL ..\..\..\SDKs\AAX\Utilities\CreatePackage.bat %OutDir% ..\..\..\SDKs\AAX\Utilities\PlugIn.ico
in Post Build
xcopy /E /I /H /K /Y /R PathToSrc $(Configuration)\$(ProjectName).aaxplugin\Contents\$(PlatformName)\
So when you select AAX build, you have something out of the box.
