I'm getting ERROR: libfdk_aac not found after it runs through a bunch of ffmpeg-4.2.1 files:

...
ffmpeg-4.2.1/tests/checkasm/vf_nlmeans.c
ffmpeg-4.2.1/tests/tiny_psnr.c
ffmpeg-4.2.1/COPYING.LGPLv2.1
ffmpeg-4.2.1/README.md
ffmpeg-4.2.1/CONTRIBUTING.md
ERROR: libfdk_aac not found

I don't notice any prior errors or issues with the build process before that.
Any suggestions?
(e.g., if it's a package we need, how come it's not included in the apt-get line that installs the other packages?)

@drscotthawley this script is quite old and no longer maintained.

In any case, did you have libfdk_aac?
It seems you may be skipping the clone part from the libfdk_aac repository.
