等待一段时间编译，不错就行。
sudo make isntall
va/va_dricommon.h is only installed if libva ls build with -Dwith_x11=yes / --enable-x11. However the header is used here if X11_FOUND is defined. And this is defined if CMake found (some?) X11 libs and headers, regardless of the libva configuration.
So the missing include error can happen if the X11 devel packages are installed but libva is compiled with X11 support explicitly disabled.
在编译libva的时候, configure 打开 --enable-x11
类似./configure --enable-x11
错误信息：
error while loading shared libraries: libva-x11.so.2: cannot open shared object file: No such file or directory
原因是libva-x11.so.2在/usr/local/lib目录中。
将/usr/local/lib添加了/etc/ld.so.conf.d/libxa.conf
执行ldconfig 更新即可。
