在openkylin,debian下编译obs-studio

一、执行cmake --preset ubuntu会提示缺少不少包，可以用下面的命令一次补齐

sudo apt install uthash-dev qt6-base-dev libjansson-dev libx11-xcb-dev libpulse-dev libwayland-dev libxkbcommon-dev libdrm-dev libegl-dev libasound2-dev libxcb-randr0-dev libxcb-xinerama0-dev libxcb-composite0-dev libpipewire-0.3-dev libv4l-dev libudev-dev libavfilter-dev libavdevice-dev libva-dev libpci-dev libsrt-openssl-dev librist-dev libspeexdsp-dev libffmpeg-nvenc-dev libvpl-dev libqt6svg6-dev nlohmann-json3-dev libqrcodegencpp-dev libwebsocketpp-dev libasio-dev libx264-dev libcurl4-openssl-dev libvlc-dev swig4.0 libluajit-5.1-dev python3.12-dev qt6-base-private-dev

二、补齐相关包之后，cmake能通过，但是会有两个警告，我们也补齐

1.缺少xcb-xinput包，使用下面的命令补齐

sudo apt install libxcb-xinput-dev

2.缺少rnnoise库，这个库没有编译好的包，需要自己下载编译安装

编译安装是可能会缺少编译工具链，可以先安装

sudo apt-get install autoconf automake autotools-dev libtool

然后从官方库中下载源代码，并且编译安装
git clone https://gitlab.xiph.org/xiph/rnnoise.git
cd rnnoise
./autogen.sh        //需要下载一个库文件，时间较长
./configure
make
sudo make install

到这里，cmake --preset ubuntu就会全部通过了

最后cmake --preset ubuntu给出了这样的结果：
