[CMake] Shipped modules that use -l

[Orion Poplawski]

It seems that there are still a lot of shipped cmake modules that use -l 
and so trigger the CMP0003 warning.  For example, FindThreads.cmake uses 
"-lpthread".


CMake Warning (dev) at src/osg/CMakeLists.txt:173 (ADD_LIBRARY):
   Policy CMP0003 should be set before this line.  Add code such as
     if(COMMAND cmake_policy)
       cmake_policy(SET CMP0003 NEW)
     endif(COMMAND cmake_policy)
   as early as possible but after the most recent call to
   cmake_minimum_required or cmake_policy(VERSION).  This warning appears
   because target "osg" links to some libraries for which the linker must
   search:
     -lpthread
   and other libraries with known full path:
 
/builddir/build/BUILD/OpenSceneGraph-2.4.0/BUILD/lib/libOpenThreads.so.2.2.1
   CMake is adding directories in the second list to the linker search 
path in
   case they are needed to find libraries from the first list (for backwards
   compatibility with CMake 2.4).  Set policy CMP0003 to OLD or NEW to 
enable
   or disable this behavior explicitly.  Run "cmake --help-policy 
CMP0003" for
   more information.
This warning is for project developers.  Use -Wno-dev to suppress it.
