[osg-users] [build] Can't build documentation

[Goj Ames]

Hi Alberto, 
Thanks for chiming in.  
I have no 'doc_' targets in my top level makefile, but I see the bits in CMakeLists.txt, so I tried:
cmake BUILD_DOCUMENTATION .

I get several messages about missing packages, (Freetype, JPEG, Jasper, ... ) which I will fix, but it gives no errors.  After this, I still have no doc_ targets in the Makefile.

....
-- Could NOT find PNG (missing:  PNG_LIBRARY PNG_PNG_INCLUDE_DIR) 
-- Could NOT find TIFF (missing:  TIFF_LIBRARY TIFF_INCLUDE_DIR) 
-- Could NOT find PkgConfig (missing:  PKG_CONFIG_EXECUTABLE) 
-- Configuring done
-- Generating done
-- Build files have been written to: /home/gjames/OpenSceneGraph

make doc_openscenegraph
  make: *** No rule to make target 'doc_openscenegraph'.  Stop.
grep doc_ Makefile
<nothing>

I'm up to date with:
commit a83a59fffe65e28ce110f542122dbf4137b93255
Merge: f013961 89fe663
Date:   Thu Mar 31 19:22:03 2016 +0100

Thanks for getting me a bit farther along, and thanks again for any other tips.
