# OpenSceneGraph
#
# Using static OpenSceneGraph libraries requires some changes to your source:
# - Define OSG_LIBRARY_STATIC
# - Use the macro USE_GRAPHICSWINDOW() to explicitly reference your graphics system
# - Use the macro USE_OSGPLUGIN(<plugin>) to explicitly reference any plugin
#   you might want to use
#
# Look at OpenSceneGraph-2.8.2/examples/osgstaticviewer/osgstaticviewer.cpp
# for an example. This example can be compiled with:
#
# i686-pc-mingw32-g++ -W -Wall -o osgstaticviewer.exe					\
# 	examples/osgstaticviewer/osgstaticviewer.cpp					\
# 	-DOSG_LIBRARY_STATIC 								\
# 	-I/path/to/mingw-cross-env-2.10/usr/i686-pc-mingw32/include			\
# 	-L/path/to/mingw-cross-env-2.10/usr/i686-pc-mingw32/lib				\
# 	-L/path/to/mingw-cross-env-2.10/usr/i686-pc-mingw32/lib/osgPlugins-2.8.2	\
# 	-losgdb_ive -losgdb_freetype -losgdb_osg -losgdb_rgb -losgdb_openflight 	\
# 	-losgViewer -losgDB -losgText -losgGA -losgSim -losgTerrain -losgFX -losgUtil 	\
# 	-losg -lOpenThreads 								\
# 	-lfreetype -lz -lgdi32 -lopengl32 -lglu32
#
# If you use other plugins, you need to add them and their dependencies in the
# right places. For example, put -losgdb_png after the other plugins and -lpng
# before -lz for the PNG plugin.
