安装irrlicht-1.8.4.zip 的时候，提示下面的这个错误。

Irrlicht/CIrrDeviceLinux.h:33:10: fatal error: X11/extensions/xf86vmode.h: 没有那个文件或目录
   33 | #include <X11/extensions/xf86vmode.h>
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

解决办法：

apt-file search xf86vmode.h

libxxf86vm-dev: /usr/include/X11/extensions/xf86vmode.h

安装缺少的包：

sudo apt install libxxf86vm-dev

从github下载vcpkg源码包

git clone https://github.com/Microsoft/vcpkg.git

进入源码目录

cd vcpkg

执行./bootstrap-vcpkg.sh

./bootstrap-vcpkg.sh

编译好后，进行安装

./vcpkg integrate install

vcpkg创建软链接

sudo ln -s /home/const/vcpkg/vcpkg /usr/bin
