Not quite all there yet but made some progress and was able to build fine.

Hi, can you provide a description of the changes you have made ?

[megrimm]

Apologies for lack of description. It has been long enough that I have forgotten what I was doing but I think the basics are paving the way for an easier PD build that can load a model relative to the patch rather than having to provide an absolute path and a way to recursively embedding dependencies for packaging and deployment.

works very nicely.

[delmenhorst]

test it. works fine.
