How do I use/install ICU and make use of it in my C++ Visual Studio 2022 project?

问题

我对C++相当新，最近几天一直在尝试使用ICU库。我已经按照ICU GitHub上的这个指南进行了操作，但成果不大。

我发现可以在本机中使用#include <icu.h>，但不确定它提供了什么功能，以及如何使用它，而且文件似乎已经剥离。这个页面讨论了在Windows上的使用情况，但不是特别具体。

我尝试按照GitHub上使用Cygwin的安装说明进行安装。安装VS2022似乎需要Cygwin。但是我未成功，输出如下：

PS C:\Users\user\Dev\ICU\icu\source&gt; bash ./runConfigureICU Cygwin/MSVC

It was created by ICU configure 73.1, which was
generated by GNU Autoconf 2.69.  Invocation command line was

I am quite new to C++ and have been trying to use the ICU library for the past few days. I have followed this guide on the ICU GitHub, to little avail.

I found that I can #include &lt;icu.h&gt; natively, but I am not sure what functionality that provides, and how to use it, and the file looks stripped. This page discusses how it is used on Windows, but it is not particularly specific.

I tried installing it following the instructions on GitHub with Cygwin. The installation for VS2022 seems to require Cygwin . I was unsuccessful, getting this output.

ICU已经作为Cygwin包可用。

请查看最新的开发包内容：https://cygwin.com/packages/x86_64/libicu-devel/libicu-devel-72.1-1

没有理由将"C++ Visual Studio 2022"与"Cygwin"混合使用，而且可能会很繁琐（我不使用Visual Studio）。

Cygwin已经包含了所有必需的开发包：

gcc-core
gcc-c++
make
cmake

还有许多其他包。请查看完整列表：https://cygwin.com/packages/package_list.html

英文:

ICU is already available as Cygwin package

See content of the last development packages
https://cygwin.com/packages/x86_64/libicu-devel/libicu-devel-72.1-1

There is no reason to mix C++ Visual Studio 2022 with Cygwin and it is likely cumbersome (I do not use Visual Studio).

Cygwin has already all needed packages for development:

gcc-core
gcc-c++
make
cmake
..

and many mores. See full list at
https://cygwin.com/packages/package_list.html
