C++ libswscale/swscale.h：没有这样的文件或目录

在Ubuntu 16.04上安装Sumo-0.30.0时，make导致以下错误：

make[4]: Entering directory '/home/<path>/sumo-0.30.0/src/gui'
g++ -DHAVE_CONFIG_H -I. -I../../src  -I/home/<path>/sumo-0.30.0/./src  -I/usr/include/ffmpeg -I/usr/local/include -I/usr/include/fox-1.6 -I/usr/include/gdal  -I/usr/local/include -I/usr/include   -msse2 -mfpmath=sse -O2 -DNDEBUG  -MT GUIViewTraffic.o -MD -MP -MF .deps/GUIViewTraffic.Tpo -c -o GUIViewTraffic.o GUIViewTraffic.cpp

../../src/utils/gui/div/GUIVideoEncoder.h:58:32: fatal error: libswscale/swscale.h: No such file or directory
compilation terminated.
Makefile:449: recipe for target 'GUIViewTraffic.o' failed

我甚至在浏览之后也找不到libswscale目录和swscale.h

根据另一篇文章，有人提到Ubuntu上的问题是ffmpeg包没有安装swscale.h

如何修复此问题？

安装软件包。它提供了/usr/include/*/libswscale/swscale.h.
