Qt Development column: Tripartite library development techniques
preface
Qt uses the libzip library, which is the base of many other libraries.
libzip
Libzip is a C library for reading, creating, and modifying ZIP files. Files can be added from data buffers, files, or compressed data copied directly from other ZIP archive files. Changes made without closing the archive can be restored. The current version is 1.7.3, released on July 15, 2020. QQ group: 1047134658 (click “file” to search for “libzip”, update the group with the blog post)
Libzip compilation
Step 1: Decompress
Step 2: Cmake configuration (VS2017 X64)
Zlib needs to be compiled before vs2017 x64 zlib, import and configure
Step 3: Generate the project
Step 4: Open VS2017 compilation
Step 5: Install
