11Zip

11Zip (or EL_evenZip) is a dead simple zipping / unzipping C++ Lib

I didn't really wanted to make my own zipping / unzipping library but as I found nothing else, I made my own.

That's why I called this lib 11Zip, 11 is the atomic number of the sodium as it describes pretty well my salty feeling when searching for a zipping / unzipping C++ Lib.

By the same time it's also a reference to 7zip.

The lib is based on zlib & minizip : https://github.com/madler/zlib

It does also include some wrapper code from here : www.vilipetek.com/2013/11/22/zippingunzipping-files-in-c/

Installation

Clone this repository using the following command :

git clone --recurse-submodules https://github.com/Sygmei/11Zip.git

(don't forget about the --recurse-submodules part or dependencies are not going to be downloaded).

Once downloaded, put the content into your extlibs/ (or equivalent) directory and put the following lines in your CMakeLists.txt :

add_subdirectory(extlibs/elzip) # Path to the 11zip

target_link_libraries(YourTargetName elzip)
