It now points to sdk version 6.0 (I do intend to make this configurable my command line)
It also added a search for libtiff to Apple builds mainly for use with osg earth."
* avfoundation: added support for IOS (CoreVideo-support is still in development, works only for SDK >= 6.0, set IPHONE_SDKVER in cMake accordingly)
* zeroconf: added ZeroConf-device-plugin (Mac/Win only, linux implementation missing) to advertise and discover services via ZeroConf/Bonjour, on windows you'll need the Bonjour SDK from Apple
* osgosc: modified the example to demonstrate the usage of the ZeroConf-plugin (start the example with the command-line-argument --zeroconf)
* SlideShowConstructor: enable/disable CoreVideo via a environment variable (P3D_ENABLE_CORE_VIDEO)
* RestHttp: mouse-motion-events get interpolated
* RestHttp: unhandled http-requests get sent as an user-event to the event-queue, all arguments get attached as user-values to the event
* modified some CMakeModules to work correctly when compiling for IOS
* fixed a compile-error for IOS in GraphicsWindowIOS
* some minor bugfixes"

Which is fragile because XCode could be installed into another directory than /Developer. (In case XCode is not installed into the /Developer directory CMake can automatically resolve the path via command line utility ${CMAKE_XCODE_SELECT} --print-path)
This issue bites me currently because the latest XCode (Version 4.3.1 - 4E1019) installed through the Mac App Store is per default installed in "/Applications/Xcode.app/Contents/Developer" and hence the 10.7 SDK in "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk"
Searching the web to find the proper way to determine the version of the Platform SDK programmatically, I found no standard way. I came up with 2 options myself:
1) Parse the path string to extract the version number
2) Read a value from the SDKSettings.plist found in the root of each SDK (e.g., "defaults read ${CMAKE_OSX_ROOT}/SDKSettings.plist CanonicalName" gives "macosx10.7")
I implemented the last option and verified that at least the following Mac OS SDKs (10.3.9, 10.4, 10.5, 10.6, 10.7) support this method. It also looks reasonably future proof. An additional benefit of this method is that it also seems to be compatible with iOS and iOS Simulator SDKs (at least for version 5.1, but I assume this also applies to older versions). This is interesting because the CMake infrastructure to build OSG for iOS currently still contains similar hard-coded paths and even requires you to manually change the cmake file to build for another iOS SDK version. In the near future I hope to address these issues, but I haven't been able to try this yet."
I added AFAIK proper defaults for several Macos X Version API targets.
* In order to determine which defaults to apply, consult the CMAKE_OSX_SYSROOT variable pointing to the used SDK, not the pure existence of an SDK.
* Defaults are now:
10.7: Support Intel 32 and 64 Bit Cocoa with imageio picture reader
10.6 + 10.5: Support Cocoa with imageio on Intel and PowerPC
10.4: Carbon, Quicktime and PowerPC
Now OSG compiles out of the box for MacOSX 10.7. , tested with gcc and clang with FlightGear."
(http://gta.nongnu.org). This allows to read and write floating point
image data. Unlike other formats, GTA also allows very good compression
ratios for floating point data. The compression method can be selected
with the COMPRESSION option of the plugin.

2nd - Script to use a 3rd party directory with basic libraries: libjpeg,libpng,libtiff,giflib,freetype,curl,gdal.
3rd - Change in the GLES library loading for Android. That should make GLES2 work properly.
4rth- Included two defines RGB8_OES and RGBA8_OES as a substitute in GLES for RGB8 and RGBA8
5th - OpenGL and GLSL version identification changed to recognize GLES versions properly
"
I also modified the CMake and pkgconfig files to append the _POSTFIX extenstion based on the CMAKE_BUILD_TYPE.
Additionally I fixed packaging/ld.so.conf.d/openscenegraph.conf.in to add a '/' betweeen the arguments since the CMAKE_INSTALL_PREFIX can't end with a '/'.

This feature has been introduced to cmake in 2.8.3, on older versions it should be ignored silently. I tested on Visual Studio 2008 with cmake 2.8.3 and 2.8.4.
See the screenshots for comparison [img]osg_solution.png[/img]
This needs few changes:
activate on global cmakelist.txt:
[code]set_property(GLOBAL PROPERTY USE_FOLDERS On)[/code]
set appropriate folder names for project type in osgMacroUtils.cmake:
[code]SET_TARGET_PROPERTIES(${CORELIB_NAME} PROPERTIES FOLDER "OSG Core")[/code]
similar for examples, applications"
