packaging support improvements

Browse source 
This grew out of my work creating an sfml port for macports, but should
be helpful for package maintainers of various distributions:

* add an SFML_USE_SYSTEM_DEPS option to ignore everything in extlibs/
  except for headers/stb_image, and use the system versions

* install pkg-config files if a pkg-config program is found
  and either lib/pkgconfig or libdata/pkgconfig exists under the
  INSTALL_PREFIX, or the SFML_INSTALL_PKGCONFIG_FILES flag is set
  explicitly

* install pkg-config files for static libs too, add the necessary
  Requires.private and Libs.private entries to the .pc files to support
  static linking

* on OS X, honor all INSTALL_NAME and RPATH related cmake variables and
  only set the INSTALL_NAME_DIR to "@rpath" if none of them is set, this
  preserves the default behavior of using @rpath but also allows
  overriding by the usual cmake mechanisms
