CPP compile error: included files not found

In my app.cpp file I have the following line: #include "indri/Repository.hpp"

However when I run make (makefile below): I get the following error:

indri/Repository.hpp:22:32: error: indri/Parameters.hpp: No such file or directory

The reason is that the Repository.hpp includes other hpp in the same folder but it uses "indri/*.hpp" instead of just "*.hpp".

What am I missing ? thanks

Did you forget to add the current directory?
