ccextractor（オープンソースクローズドキャプション抽出プログラム）のビルドメカニズムをカスタムMakefileからAutotools生成Makefileに変換しようとしています。Makefileを使ってビルドして、スクリプトは動作しますが、同等のMakefile.amはありません（未定義の参照エラーを返します）

そしてまた、すべてはgpacmp4ディレクトリ内のファイルのようなsrcのサブディレクトリ内のフルパスで行われことと、 #include <gpac/avparse.h>。すべて-I flagsが提供されているメインのccextractor.cファイル以外のファイルです。
少しでも助けていただければ幸いです。 makeがちょうど未定義の参照のエラーを表示する前に呼び出されます

PS：appreciated.Iを含む多くのことを試しているすべてのヘルプここで
はmakeが呼び出すいくつかの初期の文ですコード内の#include <path/to/header>ステートメントのパスを変更してから-IステートメントをCPPFLAGSのパスに追加してもそれは役に立ちませんでした。定義されていない参照エラーのほとんどは、src/dir/subdirなどのディレクトリのサブディレクトリにあるヘッダで宣言された関数からのもので、src/dir/までのフラグは-Iまでしか追加されず、src/dir/のファイルは#include<subdir/filename.h>のような文を持ちます。
PPS：grep -r "<Name_of_function_leading_to_error>" .をsrcに使用して、宣言ヘッダーを確認しました。
