使用OHOS SDK构建zziplib

参照OHOS IDE和SDK的安装方法配置好开发环境。

从gitee下载源码，当前最新的提交记录ID为6699e0fe8a0307b16dcc055eda04452e13abe63a。

执行如下命令：

git clone https://gitee.com/mirrors/zziplib.git

进入源码所在的目录，创建批处理文件ohos_build.cmd，内容如下：

@echo off
setlocal

set OHOS_SDK_HOME=D:\Tools\Huawei\OHOS\SDK\9
set CMAKE_HOME=D:\Tools\cmake-3.26.0-windows-x86_64
set PATH=%CMAKE_HOME%\bin;%PATH%

cmake --version
ninja --version

set SRC_ROOT=%CD%
set BUILD_ROOT=%SRC_ROOT%\build-ohos

set BUILD_TARGET=libzzip

    -DZZIPLIB_OPTIONS="-DZZIP_COMPAT=OFF;-DZZIP_PKGCONFIG=OFF"

cmake --build %BUILD_ROOT% --target %BUILD_TARGET% --config release --parallel

为了顺利通过编译，需要给现有的CMakeLists.txt打个补丁，内容如下：

diff --git a/zzip/CMakeLists.txt b/zzip/CMakeLists.txt
index c294c1f..aa4bd34 100644

进入CMD，在源码所在的目录下，执行如下命令：

call ohos_build.cmd

等待项目编译结束。

CMakeLists.txt有编码错误，导致配置项目的时候存在告警，不过不影响项目的编译。
