QMake DEPENDPATH

Hello!

I have a project, an application, split into 2 directories, each containing sources and headers, like:

fet

engine

rules.h

rules.cpp

interface

fet.h

fet.cpp

interface.pro

I compile the project with

Code:

---

qmake interface.pro

---

interface.pro used to contain this:

Code:

---

INCLUDEPATH += . ../engine

---

The target is app (an application compiled with rules.cpp and fet.cpp from the engine+interface subdirectories).

But today I read that I should also add the directive:

Code:

---

DEPENDPATH += . ../engine

---

so that when I change a header file, the application is updated.

Am I right to add the DEPENDPATH directive this way?
