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

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.

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

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

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

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."
I needed a -DCMAKE_DEBUG_POSTFIX="d" not a -D"CMAKE_DEBUG_POSTFIX=d".
This corrects the build for the CMake 2.4 and 2.6 series

first post:
"I had the problem that debug and release version of the plugins had the same name under linux. These minors modification to Registry and the CMake support files enable to have both Release and Debug version of the plugins to coexist and be found by there respective runtimes."
follow up post:
"I've gone ahead and added a preprocessor directive with the editable CMAKE_DEBUG_POSTFIX. I modified Registry.cpp to take this new preprocessor directive called OSG_DEBUG_POSTFIX while looking for libraries in Debug mode for the windows (msvc) and the linux platforms.
MinGW, cygwin and Apple are still left out this proposal."
Notes from Robert Osfield, completed the work in change d entries to use OSG_DEBUG_POSTFIX
The reason is if you want to build an application that use a library that use openscenegraph you have to build the full chain in debug or in release.
On windows you have no choice, but on linux you can link with both version without rebuilding everything ...
The patch consist only to change the line on one line
SET(CMAKE_DEBUG_POSTFIX "d")
with
SET(CMAKE_DEBUG_POSTFIX "d" CACHE STRING "add a postfix, usually d on windows")"
"Here is a collection of changes which should fix issues building the OSG with CMake 2.6.0 (along with some other changes)
CMakeLists.txt:
* Set CMP0003 to supress warning about linking against -lpthread (which is a
non-absolute library location). (CMake 2.6.x fix)
* Modified the WIN32_USE_MP and a couple of other Visual Studio specific flags
to be in an IF(MSVC) block (minor tweak to reduce exposing this stuff on MinGW builds)
* Includes my second set of glu tesselator autodetection changes that you
seemed to want but haven't committed yet.
src/OpenThreads/pthreads/CMakeLists.txt:
* Eliminates warning when compiling on Linux about spaces in link line (CMake 2.6.x fix)
CMakeModules/OsgMacroUtils.cmake:
* Tweaks to make the macros behave properly under CMake 2.6.0 (doesn't change behavior under CMake 2.4.x)
CMakeModules/Find3rdPartyDependencies.cmake:
* Adds the NO_DEFAULT_PATH option to all of the search options so that things in C:\Program Files\OpenSceneGraph aren't accidently picked up during configure time and instead only things in the "3rdParty" folder are discovered. (general bugfix)

post 2:
"Ok, hold the presses. I just discovered that for some odd reason the osgdb_* plugins under Linux aren't getting put under the osgPlugins-2.5.0 folder. Not exactly sure why this broke, the folder was there, just empty. I'll have to look into it this evening."
post 3:
"Fixed, was caused by the switch to CMAKE_LIBRARY_OUTPUT_DIRECTORY and some code in osgPlugins/CMakeLists.txt that effectively overrides LIBRARY_OUTPUT_PATH on non-MSVC compilers to dump the plugins in the plugins folder. I tweaked it to override CMAKE_LIBRARY_OUTPUT_DIRECTORY as well. Seems to work fine."
in Microsoft compilers as discussed in osg-users. There is now an
advanced option called WIN32_USE_MP (which defaults to OFF) that will
enable the /MP switch for all builds. I tucked this code block safely
within a IF(WIN32) branch."
Introduced code in BoundgingSphere, BoundingBox, ProxyNode and LOD to utilise the above settings.
Added Matrix::value_type, Plane::value_type, BoundingSphere::value_type and BoundingBox::value_type command line
options that report where the types of floats or doubles.
This is caused by the OSG_MSVC_VERSIONED_DLL hack.
there are hard-coded paths to place the dll's in the bin /dir that normally would go
in the lib/config (release/debug) dirs. Nmake has different locations for the files (no config dir).
fix: change the macro's in OsgMacroUtils.cmake for the IF(NOT MSVC_IDE) situation.
Libs go in lib/, and DLLs and executables go in bin/
To accopmplish this for MSVC_IDE the targets get a "../../bin" prefix,
for nmake this should be "../bin" (because there are no config folders).
This fix mimics the behaviour of the MSCV_IDE (visual studio) build system when building with nmake.
Note:
A change in the main CMakeLists.txt creates the needed plugin directory in the binary dir.

CMake build system, enabling this option will build the OSG against the (...) version

One can also set the default value of this option via the DEFAULT_GLU_TESS_CALLBACK_TRIPLEDOT

this issue come from the CMake FAQ"
the osgsimpleviewerQt4 example in my Visual studio solutions... After
looking into it it seems that you cannot have both Qt3 and Qt4
enabled. After modifying the root CMakeLists.txt to use :
FIND_PACKAGE(Qt) which should ask you to choose betwwen Qt3 and Qt4
if you have both
instead of :
FIND_PACKAGE(Qt3)
FIND_PACKAGE(Qt4)
I had the project generated. But then due to the way CMake handles Qt4
I had to modify osgsimpleviewerQt4's CMakeLists.txt to have the binary
link with QtOpengl4. "
"
Here are more changes for the CMake scripts:
- I removed CMAKE_INSTALL_PREFIX in FindOpenThreads as a follow up to
the discussion thread.
- I introduced an experimental CMAKE_PREFIX_PATH to replace it.
- I added CMAKE_PREFIX_PATH, CMAKE_INCLUDE_PATH, and
CMAKE_LIBRARY_PATH to the CMake GUI so users can enter values there
instead of in the environment.
- I added OPENSCENEGRAPH_*_VERSION variables (MAJOR, MINOR, PATCH).
These should be kept up-to-date with the real version numbers. Mac
bundles like to have version information so users can find out the
version they are running through standard About panels and also
automated system reporters for troubleshooting/bug tracking. In
theory, this information could be used for library versioning.
We should do the same for OpenThreads, but I forgot about it.
- I added some Mac Info.plist stuff (which uses the version information).
"
I was using ${FOO_CONFIG_HAS_BEEN_RUN_BEFORE} instead of just
FOO_HAS_BEEN_RUN_BEFORE.
In this case, it happened to work out to still be correct, but in
general it shouldn't have the ${}. (I really hate this syntax.)"
a bug regarding when to set the debug version. It waited until both
include and library were set, but it shouldn't wait on include.
Also added a fix to the optional warning flags."
"
Changes include:
A internal cache flag that can be used to detect if this is the first
time running the CMake configuration. This is needed to work around
stupid CMake UI shortcomings about the UI not reflecting anything you
SET unless you use FORCE. But if you use FORCE, you override anything
the user may try to set/override unless you have an exception check.
It turns out the exception check you need is often the first-run
check. This flag is potentially useful for other things too.
An optional switch that turns on more aggressive warnings based on
your compiler.
Some Apple specific stuff for detecting the OS version and enabling
Universal Binaries (and some additional compiler flags that are good
but gcc version dependent). The version check code is unfortunately
really fragile. I need to lobby CMake to return the OS X version
number for us. FYI, building Universal will fail with the current
CMake release due to a bug, but is now fixed in CVS.
"
It should not be introusive to any other palatform apart MSVC, but in order to link to debug-specific libs
I had to change plugins CMakeLists to differentiate debug/release linkage, I have used the same macro used in core libs
Now the macro used for plugin and examples linking test for existance of TARGET_LIBRARIES_VARS
that holds the names of the variables that have to be used for linking"
