    Link against GIO_LIBS explicitly
    
    to avoid
    
    libtool: link: gcc -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -g -O2 
-fdebug-prefix-map=/build/gtk-vnc-0.6.0=. -fstack-protector-strong -Wformat -Werror=format-security -Wl,-z 
-Wl,relro
     -Wl,-z -Wl,now -o .libs/vncconnectiontest vncconnectiontest-vncconnectiontest.o  ./.libs/libgvnc-1.0.so 
-lz -pthread
    /usr/bin/ld: vncconnectiontest-vncconnectiontest.o: undefined reference to symbol 
'g_io_stream_get_output_stream'
    //usr/lib/x86_64-linux-gnu/libgio-2.0.so.0: error adding symbols: DSO missing from command line
    
    Also make the use of *_CFLAGS and *_LIBS match.
