This adds zlib as dependency to make it possible to find in FindFFMPEG.cmake. Also FFmpeg likes to autodetect zlib for additional features on compilation. This removes the check for stdint.h, as it is included since MSVC 2010 and does not always find it. To enable static linking on windows, bcript had to be added: avutil.lib(random_seed.o) : error LNK2019: unresolved external symbol _BCryptOpenAlgorithmProvider@16 referenced in function _av_get_random_seed avutil.lib(random_seed.o) : error LNK2019: unresolved external symbol _BCryptCloseAlgorithmProvider@8 referenced in function _av_get_random_seed avutil.lib(random_seed.o) : error LNK2019: unresolved external symbol _BCryptGenRandom@16 referenced in function _av_get_random_seed
