[Qgis-developer] CMake cleanup and OS X frameworks

[Tom Elwertowski]

Hi William,

I encountered the following error using your update:

CMake Error at images/icons/CMakeLists.txt:12 (ADD_SUBDIRECTORY):
   add_subdirectory given source "mac" which is not an existing directory.

It looks like icon files weren't moved from src/mac to images/icons/mac.

I also put all global header installation (qgsconfig.h, qgisplugin.h, qgsrendererplugin.h) in qgis_core, since in the OS X framework setup there is no place for random headers.

I couldn't make qgispython a framework because it's loaded dynamically and the Qt dyld functions expect standard file extensions, and a framework has none (the binary inside the framework, that is).  Really, grass and sqlanywhere don't need to be frameworks, maybe I got carried away there ;)

This gets around the potential problem of the internal relative path linking, and makes the libraries more accessible.  The cmake option is QGIS_MACAPP_INSTALL_DEV (bool).  They are installed by default in /Library/Frameworks, but this can be changed with QGIS_MACAPP_DEV_PREFIX.

(A proper framework header references other framework headers prefixed by the framework name, ie #include<qgis_core/qgis.h>.  Needs some discussion about reorganizing the headers in QGIS, if there is interest.)
