 此项目仍在早期开发阶段, 且并没有考虑开始发行, Beta版都不! 不过如果您等不及了, 可以编译此库以使用它.  
 注意, 目前我们使用的编译工具*xmake不支持在ARM64上进行运行/编译*, 除非您在X86/X64机器上进行交叉编译, 否则您将无法使用ARM64版本的EASYCROSSPLATFORM.

 If you cannot wait to see it,

    b) If you are building under Linux / Unix / MacOS, Simply Install LibCurl and you should be good to go.  
 2) simply run xmake in the directory to generate a static/shared library that you can use.  
 Remeber that the lib file generated is not cross-platform betweeen Win and Linux, and between different versions of Linux.  
+*If you are running Linux, please read Linux_BuildOptions.txt  
 You need to generate lib file each time when you are switching platforms.
