39cecd2a72 From Philip Lowman, "Here's the promised cleanup of the OSG's CMakeLists.txt files for the src/ folder. I'll submit the others separately. 
Also, there was also a small bug in osgDB's CMakeLists.txt that was causing an error when I tested with CMake 2.4.4.

IF(${OSG_DEFAULT_IMAGE_PLUGIN_FOR_OSX} STREQUAL "quicktime")
was changed to
IF(OSG_DEFAULT_IMAGE_PLUGIN_FOR_OSX STREQUAL "quicktime")
"
