Subject: Adding Albrecht's CMakeLists.txt patch

    Albrecht submitted this in issue 358.
    Tested the variations:

    	cmake ..		                               -- examples and cairo off
	cmake -D FLTK_BUILD_EXAMPLES=on                        -- examples on, cairo off
	cmake -D FLTK_BUILD_EXAMPLES=on -D OPTION_CAIRO=on ..  -- examples on, cairo on

    When examples are 'on', they build into the bin/examples directory.
