通过vcpkg安装cgal.

Question

我正在尝试使用vcpkg安装cgal.在此之前我没有vcpkg，是通过git安装的，所以这是我的第一个包(如果我理解正确的话)。我不知道什么是引导过程，我也没有尝试安装另一个包。

我在终端中有这样的错误：

Error: vcpkg was unable to detect the active compiler's information. See above for the CMake failure output.

运行此命令后：

./vcpkg.exe install cgal:x64-windows

但是如果我理解正确的话，它是在这个过程中安装的，因为在“./vcpkg/downloads”中有“ZIP-file cmake-3.20.1-windows-i386”。

为了让Python库中的一些函数正常工作，我需要安装这个cgal.所以我不完全理解发生了什么.在日志中，我看到了以下内容：

The system cannot find the path specified.
ninja: build stopped: subcommand failed.

通向什么的路径？到编译器？但是它是什么呢？

我想您使用的是Windows，如果是这样的话，首先您需要满足prerequisites。请确保按照here中概述的安装和设置步骤进行操作。其次，请尝试使用"--debug“选项进行安装，以获得完整的日志。

从PowerShell控制台运行它。
