Subject: [PATCH] From Philip Lowman, "If you change CMAKE_INSTALL_PREFIX in
 the cache editor after building the OSG, it causes the entire project to
 rebuild (at least with the CMake makefile generator due to changing
 preprocessor definitions applied across all targets).

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."
