[QGIS-Developer] MacOS packaging

[William Kyngesburye]

I created the Mac app bundle option.  I never fully extended it to 3rd party libraries because I don't have much interest in hiding the GDAL stuff.  Rather than do something new, I think this should be expanded.

Also, there is the problem of extra GDAL formats.  I include everything non-GPL or commercial that I can in my GDAL Complete, with extra plugins for the GPL and commercial stuff - ECW, MrSID, GRASS (not completely sure about that one, GPL-wise), FileGDB, GeoPDF (Poppler).

In a full bundled QGIS, I don't think bundling ECW or MrSID would work.  So you'd still need a plugin installer (not a QGIS plugin) to add those to QGIS in some sort of global application support location like I do with GDAL now.

By standalone I mean that there will be a single package (.pkg) file that will be extracted to /Application folder and will contain all dependencies (GDAL, Python3, PyQT, Qt libraries, ...) and will be working without any additional installation steps (similar to any application you install via App Store).

I hope I can wrap the last bits next week and be able to produce QGIS 3.4 release and QGIS master nightlies on some Mac Cloud server. I used osgeo4mac homebrew for dependencies, since it looks like it is the most maintained package manager with osgeo libraries for MacOS. Usage of Conda packages could be better, but the number of downloads and the activity in any available repositories is not convincing.

But it seems to me that only bundling of Qt libraries is actively maintained [QGIS_MACAPP_BUNDLE=1]and bundling of rest of libs (gdal, libzip, geos, etc.. ) [QGIS_MACAPP_BUNDLE=2 and 3] is not implemented/maintained. Also I am not convinced that CMake scripting language is best tool for such task. (due to reconfiguration on change, syntax/readability compared to python, tools available for path handling, ...)
