Hi Robert,

sorry for the long delay on my side. I am also swamped with jobs here. But 
Today I have taken some time for osg again ...

Well, this is required for out of source builds.
The generated config file will be put into the build directory during build 
time. The build directory might be different from the source directory. So to 
make the compiler find this configuration file, it will need that include 
path.
