二、DeepStream GTK4环境安装
由于我使用的GTK4开发的GUI软件，而Jetson系统是Ubuntu20.04版本。Ubuntu20.04默认是不支持安装GTK4。

安装gtk-4.8.3
harfbuzz版本低错误
因为Ubuntu20.04最高支持安装harfbuzz=2.6.4
编译过程中出现的这两个未引用错误，是因为上面那两个函数出现在 2.6.8 以上版本。
我选择安装harfbuzz 2.9.1：https://github.com/harfbuzz/harfbuzz/archive/refs/tags/2.9.1.tar.gz
meson setup build --prefix=/usr/local/harfbuzz-2.9.1
cd _build && ninja -j 8 && sudo ninja install
