Geoff McLane:

1. The variables  SIMGEAR_CORE_LIBRARIES and
SIMGEAR_CORE_LIBRARY_DEPENDENCIES are
no longer set... hence the need to hard-code 'SimGearCore'
in the target_link_libraries()

2. And -lfreetype means the linker must know the specific
link path to it, while the variable FREETYPE_LIBRARIES
contains the fully qualified path to the library.

3. Improved the 'found glut' message to show exactly what
was found, and being used... This is due to the user possibly
also have the near binary compatible glut32.lib found, which
will fail in the link due to some freeglut extensions have been
used.

4. Adding the define -DFREEGLUT_LIB_PRAGMAS=0  is
necessary to stop the freeglut headers from using a MSVC pragma
to declare the library, which will /not/ not be found...

5. In Windows the glew library is not -lGLEW, and even if it
was, it would not be found, without adding a link_directories(
path/to/library ),
while the GLEW_LIBRARIES variable has the fully qualified path.
