Hi Robert,I have restored MSVC disabled warnings in osg/Export. Difference is they are now disabled only when OSG_DISABLE_MSVC_WARNINGS macro is defined. This macro is set through CMake options and autogenerated in osg/Config. Simon suggested that it would be cool if we had more control over selected warnings. I tried to learn how to make selection of individual warning numbers possible, but had to gave up as my cmake skills were not sufficient. The only way I saw this possible would be adding one define for each MSVC warning number. But many definitions seemed too be to much clutter for osg/Config file so I rejected thar idea. For this it would be cool if autogenerated Config entries could more powerful than simple #define/#undef flags. Maybe Cmake gurus know how to do it.
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
Cheers,Wojtek

# Okay, here's the problem: On some platforms, linking against OpenThreads
# is not enough and explicit linking to the underlying thread library
