Question

首先，我是这个领域的所有新手，所以如果我要事先提出一些愚蠢或毫无道理的事情，对不起，那么让我们说清楚一点吧...我正在尝试向ffmpeg添加功能，以及我要说些什么。知道我必须修改CONTROL文件和portfile.cmake，但似乎还不够，我不理解错误，而且我无法在互联网上获得有关此信息的更多信息，因此，如果您能给我一些信息，如何正确地做到这一点，就已经准备就绪了对我来说很重要我将保留部分代码和错误文件

**portfile.cmake:**
if("libxml2" IN_LIST FEATURES)
    set(OPTIONS "${OPTIONS} --enable-libxml2")
endif()

**CONTROL:**
Feature: libxml2
Description: Libxml2 is the XML C parser and toolkit developed for the Gnome project (but usable outside of the Gnome platform)
Build-Depends: zlib, libiconv, liblzma

**Command Prompt after (vcpkg install ffmpeg[libxml2]:x64-windows)**
CMake Error at scripts/cmake/vcpkg_execute_required_process.cmake:72 (message):

Error: Building package ffmpeg:x64-windows failed with: BUILD_FAILED
Please ensure you're using the latest portfiles with `.\vcpkg update`, then
submit an issue at https://github.com/Microsoft/vcpkg/issues including:
  Package: ffmpeg:x64-windows
  Vcpkg version: 2019.09.12-nohash**strong text**

**Log Error file:**
=== CONFIGURING === ERROR: libxml-2.0 not found using pkg-config

If you think configure made a mistake, make sure you are using the latest version from Git.  If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem.

感谢您的关注，问候佩德罗·库尼亚！
