Set of fixes which had to be made in order to have dependencies built
on own laptop:
- Require bison as a dependent software. It is required by ISPC.
On macOS it is required to be installed via Homebrew. This is because Bison from Xcode toolchain is too old.
- Made sure Boost is compiled using clang.
Without this gcc was used, and some unsupported command line argument was passed to it.
- Modify OGG in a way which does in fact pull fixed sized types. They are defined in stdint.h.
Without this fix FFmpeg will not detect presence of OGG because the test program fails to compile.
- Force disable zstd compression and make wepb optional for the TIFF library. Without this TIFF might pick up development libraries from Homebrew.
