[Qgis-developer] Qgis Xcode project test

[William Kyngesburye]

My Xcode project is ready for some testing.  There is a readme in the  
project for configuration and building, and another readme for  
developers with some random notes on maintainance and the structure of  
the project.

Comments and suggestions welcome.  Especially on the configuration - I  
tried to make it as painless as possible, but it's still not automatic  
like running a configure command to search out dependencies.  There  
are layers of configuration for dependencies, and I think most people  
will only need the first 1 or 2 layers.  (See the Qgis install  
document for details on installing dependencies)


Other notes:

- a single-architecture (ie native) build should run faster than a  
cmake build.  This is because Xcode compiles sources in parallel,  
fully utilizing all processors and cores.  A universal build will be  
faster than in cmake if you have more than 2 processors/cores, for the  
same reason.

- I figured out how to get the bundled Qt frameworks to not get  
confused with an installed Qt: bundled frameworks (in general) must be  
installed in an application's Frameworks folder, otherwise the OSX  
linker loads installed frameworks over bundled copies.

This also applies to the help viewer app.  To get around this, I  
create a symlink in the qgis_help.app bundle pointing to the Qgis.app  
Frameworks folder.  qgis_help.app also needs the empty qt.conf file to  
fix the problem of loading the installed Qt plugins.

- In addition to using a Frameworks folder, I moved a few other things  
around: share/qgis stuff is in Resources, qgis plugins are in the  
package PlugIns folder, alongside the Qt imageformats, includes are in  
Headers.  I left the qgis libraries in MacOS/lib because the dynamic  
loading of libqgispython is hardwired to this folder, might as well  
keep all libraries there.

- there's a debug configuration which can be used in the Xcode debugger.
