qt-5.15.2 源码编译 Linux

QT官方源码下载地址：https://download.qt.io/archive/qt/5.15/5.15.12/single/qt-everywhere-opensource-src-5.15.12.tar.xz

安装 Qt 所需的依赖：
sudo apt install build-essential libgl1-mesa-dev libxkbcommon-dev libnss3-dev libdbus-1-dev gperf flex bison

安装 xcb 相关：
sudo apt-get install '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev libxkbcommon-x11-dev
这一步比较关键，因为涉及到编译之后有 libqxcb.so，如果缺失会导致错误。

如果需要使用到 QWebEngine 模块，那么需要安装以下依赖库：
sudo apt install libxcursor-dev libxcomposite-dev libxdamage-dev libxrandr-dev libxtst-dev libxss-dev libdbus-1-dev libevent-dev libfontconfig1-dev libcap-dev libpulse-dev libudev-dev libpci-dev libnss3-dev libasound2-dev libegl1-mesa-dev gperf bison nodejs
