+# This file allows to configure osgVisual with CMAKE to generate native build solutions.                #

+# Specify the following environment variables to use osgVisual and this CMAKE script:                   #
+#       * OSG_ROOT: Path to your 32 bit (x86) OSG, e.g. D:\OSG\OpenSceneGraph-2.9.8_x86                         # 
+#       * OSG_ROOT_X64: Path to your 64 bit (x64) OSG, e.g. D:\OSG\OpenSceneGraph-2.9.8_x64                     #
+#       * OSG: Path to your 32 bit (x86) OSG and 3rdParty binary folder,                                                        #
+#                e.g. %OSG_ROOT%\bin;D:\OSG\3rdParty\bin\x86                                                                                    #
+#       * OSG_X64: Path to your 64 bit (x64) OSG and 3rdParty binary folder,                                            #
+#                e.g. %OSG_ROOT_X64%\bin;D:\OSG\3rdParty\bin\x64                                                                                #
+#       * PATH: Extend with %OSG% or %OSG_X64% to use OSG and osgVisual from command line,                      #
+#                e.g. PATH=%PATH%;%OSG%                                                                                                                                 #

+#       NOTE:   On Visual Studio and x64 Arch, CMAKE uses the project settings to specify the           #
+#                       correct x64 OSG path, so you can use osg as 32 bit in your system path.                         #
