From Mathias Froechlich, "Attached the collected fixes I needed to compile with all of them.

Most notable the __hpux define stuff. The __hpux__ variant seems to be not
defined which resulted in a compile error at this time. Consequently I have
replaced all occurances of __hpux__ with __hpux. And huge surprise: now osg
plugins are found and loaded correctly ...
The next notable one is the MSVC_IDE fix which makes the nmake Makefiles cmake
generator target behave like the ide one. Showed up because I started to do
scripted builds with nmake instead of devenv...
The rest is the usual bunch of stuff that just happens during normal
coding ..."
