ofxOsc (and similarly structured addons -- no include dir) fail to compile w/o adding src to header search paths.

Hey there ... maybe I'm doing it wrong, but for whatever reason when I add ofxOsc via OFPlugin, compilation fails because the oscpack headers (which, unfortunately are in its src folder) are not in the header search paths. I'm not sure what the solution is (other than conditionally add the src folder if no 3rd party include folder is found). Anyway, again, maybe I'm using it wrong, but if not, I wanted to note that here. Thanks for all of your work on this supertool @admsyn.

Hey @bakercp, yeah ofxOsc is a bit of a confounding case for OFPlugin's header path logic. I haven't really had the heart to change the logic to "add all paths as include paths", but maybe that's the right way to go (or maybe just as a special case for ofxOsc).

Oops, should have searched closed issues :) yeah not sure what the best to do it is. As a core add-on, an exception may be justified.
