Introduced a new callback osgDB::FindFileCallback that overrides the default behavior of findDataFile/findLibraryFile.
Introduced support for assigning ReaderWriter::Options directory to PagedLOD.
Introduced new osgDB::FileLocationCallback for assistancing the DatabasePager to know when a file is hosted on a local or remote file system.
Converted Present3D across from using libxml2 to using the new osgDB::XmlNode/XmlNode::Input classes from Xml Parsing.
This changes removes the dependency on libxml2, and allows the present3D application and p3d to work on all platforms.

Since this is a workaround for a bug in a beta OS (which may or may not be fixed, since it's mentioned in their release notes so they may just leave it as it is) I've marked the option as advanced, default to OFF, and clearly documented it as being useful for Windows 7 only. I'd like to be able to test for Windows 7 directly instead of the blanket IF(WIN32), but I can't figure out if this is possible in CMake.
Here's the modified CMakeLists.txt. It's a small change, with low impact, but will be useful to others who test out this OS and when it comes out. Note that I'm not familiar with this option in general, and didn't get any feedback to my questions in the above-mentioned thread, one of which was: Could we just add this option to all builds? What is the impact? That's still unclear to me, but without it OSG executables don't build, and the article I linked didn't seem to present any ill effects to enabling the option."
1. Makes IF/ELSE/ENDIF code blocks easier to read by replacing code like this:
IF(FOO)
MESSAGE("FOO is true")
ELSE(FOO)
MESSAGE(" ??? ELSE(FOO)??? ")
ENDIF(FOO)
with this:
IF(FOO)
MESSAGE("FOO is true")
ELSE()
MESSAGE("FOO is clearly false")
ENDIF()
2. Also adds an ELSEIF() where it makes sense to do so (safe to use as of CMake 2.4.4)"
talking about in the LIB_POSTFIX thread. It is a bit verbose perhaps
and the message I emit during the make install step flashes by and
gets burried under all "installing..." and/or "up-to-date..."
messages. I have posted on the cmake mail list on ways to do this
better.
The submission adds:
* message to user during configuration that s/he's eventually going o
install to ${CMAKE_INSTALL_PREFIX}lib${LIB_POSTFIX}
* if system has /etc/ld.so.conf.d and it is a dir generates
packaging/ld.so.conf.d/openscenegraph.conf and creates a custom target
for installing it (target must be run explicitly of course). User is
notified of this during configuration (may not be necessary)
* emit a message during installation that libraries are put in
<same-as-above>. This message unfortunately gets emitted to soon for
the user to see it
* I added "COMPONENT libopenscenegraph-dev" to the pkgconfig.pc's
install command
* Moved the section with OSG_CONFIG_HAS_BEEN_RUN_BEFORE as close to
the end of CMakeLists.txt as I dared. This is the intent of this
construct I think."
openscenegraph.pc and openthreads.pc files with OSG's installation values.
Then I install those files into the expected path for pkg-config (this can
also be modified through PKG_CONFIG_PATH environment variable). Therefore
those of us who are using pkg-config for linking can easily select which
version of OSG we want to use."
name of the top folder in each package to OpenSceneGraph-x.y.z
Noone else has had an opinion on whether compiler and it's version
should be part of the package filename on their platform/setup so I'll
leave it as is. That is - No action is taken for compilers other than
msvc but one can easily add this information to the cmake cache
regardless of platform.

streamlined for tgz and has most of the features that Robert, J-S and
Sukender requested in december. I have an idea of how to discover the
vc80 sp1 or not but haven't had time to implement. The script is
completely reworked and now doesn't include cmakes' bundled
CPack.cmake script at all. In summary:
* filenames are
<package>-<osgversion>-<platform>-<arch>[-compiler]-<configuration>.tar.gz,
ex. libopenscenegraph-2.7.9-Linux-i386-Release.tar.gz,
libopenthreads-dev-2.7.9-win32-x86-vc80sp1-Debug.tar.gz
* targets (projects in msvs) are generated for each specified
component, a target that packages everything that is installed
(openscenegraph-all) and there's a target for running all other
packaging targets (Package ALL on msvs, package_ALL in unix
makefiles).
* It is possible to set the compiler in ccmake (cmake-gui, whatever you use)
* the top folder in packages is the same for all packages (OpenSceneGraph-x.y)
* the packaging support is limited with cmake-2.6.0 and not as
dynamic. With cmake-2.6.1 and later building the gdal plugin (for
example) will create a package_libopenscenegraph-gdal target. With
cmake-2.6.0 only the ones that are always built (libopenscenegraph,
libopenscenegraph-dev, openscenegraph, libopenthreads,
libopenthreads-dev
* i found a better way to decide whether cpack is available to guard
the BUiLD_OSG_PACKAGES option"
of cmake-2.6.0. As a side note I just installed cmake from the ubuntu
repositories and got cmake-2.6.0-4ubuntu2 and this one produced the
currect CMAKE_CXX_FLAGS_RELEASE (-O3 -DNDEBUG). This CMakeLists is
tested on linux with cmake versions 2.4.8, 2.6.0, 2.6.2 and
2.6.0-4ubuntu2
* Added quotes around CMAKE_CXX_FLAGS var to help cmake-2.6.0 pick up
that it really is a string value
* Removed quotes around values that we set in
OSG_AGGRESIVE_WARNING_FLAGS. This makes OSG_AGGRESIVE_WARING_FLAGS be
of LIST type so the foreach constructs can behave as I planned."
that set aggressive warnings in CMAKE_CXX_FLAGS and the on that
processes the source tree(s) or the newly set flags wouldn't take
effect until second consecutive configure.
I also replaced the internally cached variables that managed the
aggresive warnings with explicit adding and removing of flags in
CXX_FLAGS
For apple we first required min cmake version 2.6.0 and then had code
warning about using 2.4.x"
* Removed processing of include/OpenThreads in the OpenSceneGraph refman
* Clears the mark_as_advanced property of the BUILD_DOCUMENTATION
cmake variable (so it gets visible in simple view).

Updated all doxyfiles under doc/Doxyfiles. They are now all processed
by cmake but make targets are only generated for
OpenSceneGraphReferenceDocs and OpenThreadsReferenceDocs. The others
can be run with doxygen directly in <builddir>/doc.
Fixed a copy-paste in openthreads sproc and pthreads CMakeLists
Added the osg logo to the html footers
Added possibility to get generation of chm files.
CMakeLists (toplevel):
Added install of osg and ot reference docs. This also generates
packaging targets of openscenegraph-doc and openthreads-doc if you
have packaging enabled
Removed the unused USING_OP_OT_TRIPLE_SET since there was no way of
enabling it anyway
Removed BUILD_REF_DOCS. IMO it was redundant - BUILD_DOCUMENTATION
does the same thing and we get that anyway from including
Documentation.cmake.
OsgCPack.cmake:
Removed generation of PACKAGE_SRC for msvc
Added special handling for -doc packaging targets - they don't require
system, architecture or compiler"
Better package naming. example
openscenegraph-core-2.7.7-Linux-i386.tar.gz on my ubuntu laptop and
openscenegraph-core.2.7.7-win32-x86-vc80.tar.gz on winxp.
CMakers will not get options for selecting compression format. TGZ
goes for all platforms (on win32 I use 7zip)
The wrappers is now given the COMPONENT name
libopenscenegraph-wrappers. Feel free to change the name.
On windows with visual studio the OsgCPack script make some efforts to
discover the compiler used but support is a bit poor so I've given
CMake acces to OSG_CPACK_COMPILER to provide some mean to name the
compiler.
stop
The platform part is taken from CMAKE_SYSTEM_NAME and for windows I
change this to win32 or win64 based on CMAKE_CL_64. This might not be
necessary if the arch part has that information. This information is
taken from CMAKE_SYSTEM_PROCESSOR. I only have 32bit here so if some
of you could uncomment line 15,16 in OsgCPack.cmake and report what
cmake report it would be nice. I'm especially interested anything but
win32 and linux32"
consider these initial cpack support scripts. It is hidden behind a
BUILD_PACKAGES option so won't affect the normal user. The submission
1) set the COMPONENT attribute on all cmake install commands.
COMPONENT names are according to
http://www.openscenegraph.org/projects/osg/wiki/Community/Packaging
2) provide cmake script and a template for creating CPack
configuration files. It will generate target for creating packages
with everything that gets "installed" (make package on unx, project
PACKAGE in MSVC) plus targets for generating one package per COMPONENT
(i.e. libopenscenegraph-core etc.).
I have temporariliy uploaded some examples to
http://www.openscenegraph.org/projects/osg/wiki/Community/People/MattiasHelsing
If this submission makes it into svn we can develop it to generate
rpms, installers for windows and mac (I know at least J-S don't like
these but there may be others who do ;) and even DEBs (not sure if we
can make them "ubuntu-ready" but they eventually may - at least we
could put a deb on the website)"
I have not reverted added Compiler options. I assume that one may want to have warnings enabled for the application but may not want to see them while OSG libraries and examples compile.
Modified files:
osg/Export - now explicitly includes osg/Config to make sure OSG_DISABLE_MSVC_WARNINGS is read
osg/Config.in - declares OSG_DISABLE_MSVC_WARNINGS flag to be added to autogenerated osg/Config
CMakeLists.txt - declares OSG_DISABLE_MSVC_WARNINGS as option with default ON setting

I suggest moving the definition of OSG_DEFAULT_LIBRARY_PATH (which is responsible for this global rebuild) into osgDB/CMakeLists.txt which is the only library in the code where this definition is (and is likely ever to be) used. This way if the user changes it, only osgDB will rebuild."
set to off. But could be activated/decativated via CMake as well as system
environment variable. I also modified src\osgViewer\CMakeLists.txt to turn
off this workaround by default as suggested."
CMakeLists.txt changes: "I installed latest Cmake(2.6.1) on a new machine and got a CMP008
warning from cmake. This fix set up osg to use the old behaviour which
have worked before. We might set this to NEW but I need to do more
testing first. I'l be able to test this on winxp with msvc80/90 and
ubuntu hardy with gcc-4.2.

mode. Nevertheless, the code doesn't acknowledge that, so I had problems with
debug versions of the library not being able to open their plugins whereas
the release versions worked fine.
I have made the same changes in Registry.cpp that are available for the rest
of platforms appending that "d" to their plugins. I have also updated the
CMakeLists.txt file to get "_DEBUG" defined at compilation time. I have
copied the already existent conditional block because of cmake's bizarre
operator precedence. Since Cygwin defines both CYGWIN and WIN32, the
following would suffice:
IF(CYGWIN OR UNIX AND NOT WIN32 AND NOT APPLE)
Sadly, it actually doesn't work, so I wrote a new conditional block just for
Cygwin. I could join the two blocks when the parentheses support is added in
newer versions of cmake."
