Fix linking

Linking failed on my machine with error:
> /usr/lib/gcc/x86_64-pc-linux-gnu/4.8.3/../../../../x86_64-pc-linux-gnu/bin/ld: hdmi.o: undefined reference to symbol 'jpeg_CreateDecompress@@LIBJPEG_6.2'
> /usr/lib64/libjpeg.so.62: error adding symbols: DSO missing from command line

Adding -ljpeg fixed the issue for me
