Errors occur when #including "$(OutDir)"\include\fdk-aac\FDK_audio.h

[Kevin Barnes]

After building this project, FFmpeg or anything else that attempts to #include FDK_audio.h from the output directory will get an error like this:

Cannot open include file: 'syslib_channelMapDescr.h': No such file or directory (compiling source file ..\libavcodec\libfdk-aacdec.c) libavcodec d:\users\kevin\documents\code\ffmpeg\msvc\include\fdk-aac\fdk_audio.h

Context

This is happening because FDK_audio.h has this line:

#include "syslib_channelMapDescr.h"

This header is not copied to the output directory, so no other projects should be expected to find it.

Expected Behavior

The SMP FFmpeg project should be able to include fdk-aac headers without errors

Actual Behavior

The SMP FFmpeg project can't include fdk-aac

Steps to Reproduce

1. Configure FFmpeg with --enable-libfdk-aac
2. Build fdk-aac
3. Attempt to build ffmpeg

Your Environment

Visual Studio 2017
Windows 10, 1809
