    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.
