📦 A fork of https://github.com/stonewell/lib7zip allowing multiple-item extraction

lib7zip

This is a fork of https://github.com/stonewell/lib7zip.

The original description follows:

• A library using 7z.dll/7z.so (from 7-Zip) to handle different archive types.
• lib7zip is based on 7zip/p7zip source code, but NOT including any source code from 7zip/p7zip.

This fork includes the following changes:

• Port from autotools to CMake
• Add automatic downloading of 7-zip sources with cmake
• Work around "redefining GUIDs", see this discussion for an actual explanation
• Only look for 7z.dll or 7z.so in the executable's directory, as opposed to:
  • a bunch of paths on linux/mac (in /usr, /usr/local, and ".")
  • all entries of %PATH% on windows (which includes ".")
• Add a new API, ExtractSeveral
  • Pass a subclass of C7ZipExtractCallback
  • This allows extracting formats like .7z faster, otherwise it keeps re-extracting the same blocks

This fork was made for internal purposes, to expose the 7-zip API to https://github.com/itchio/butler.

As a result, I probably won't be accepting issues/PRs on this repo. Cheers!

Do you really need 7z sources instead of LZMA SDK?
