-For Boost you will need the headers as well as the `iostreams`, `filesystem`, `date_time`, `system` and `program_options` libraries. Older Boost version may work but are not actively supported. The boost `iostreams` library needs to be build with zlib and bzip2 support.

 While innoextract can be built without liblzma by manually setting `-DUSE_LZMA=OFF`, it is highly recommended and you won't be able to extract most installers created by newer Inno Setup versions without it.
