我正在尝试在现有应用程序上运行一个名为crest的工具。我的第一个目标应用程序是 Apache。输出（如下图）表明没有找到一些头文件。它们位于源文件夹中的其他目录中。其中之一是 \httpd-2.2.14\srclib\apr\include。我宁愿不更改 apache 的源代码，因为我希望对 Apache 中的大量文件运行此命令，然后将相同的技术应用于其他几个应用程序。
我的问题是：
1）我怎样才能做到这一点，以便在查找这些引用的包含文件时，它会找到它们所在的正确目录并将使用该目录。我可以定义目录。有朋友提到改变命令行输入，或者构建环境变量？
其他想法/建议将不胜感激。
谢谢大家。
运行 crest 的命令是： ../bin/ crestc ../../httpd-2.2.14/server/request.c -dfs
我得到以下输出：
