osx / macos - templates and libs issues

[dimitre]

Today I was trying the projectGenerator with individual libs from osx / macos to see if libs are working and found some issues:

• osx template: doesn't work. libs are installing in "macos" folder instead, example: ofxOpenCv/libs/opencv/lib/macos
  I don't understand this one, it is the only apothecary libraries that are installing in a folder with a different name than the platform name. can you take a look on this @danoli3 ?

• macos template is not in json format, so it is not editable by PG.
  Updating the template shows that there is some new folders there, linking some missing files (swift?)

Apothecary action for "osx" template is called build-macos.yml. it can be easier if we keep the same as platform name
and "osx" libraries are using "macos" name inside "lib" in each addon. this is the only non standard name (different than platform / template name) for this folder
