Subject: [PATCH] From Alberto Luaces, "I have modified CMakeLists.txt in order
 to make CMake fill the existent openscenegraph.pc and openthreads.pc files
 with OSG's installation values. Then I install those files into the expected
 path for pkg-config (this can also be modified through PKG_CONFIG_PATH
 environment variable). Therefore those of us who are using pkg-config for
 linking can easily select which version of OSG we want to use."
