[Qt-interest] How should sources in subdir be compiled?

[André Somers]

I have no experience with CMake, but in QMake, I can suggest some options:

Simplest is to just add the files with the subdir included in the path:

HEADERS += GUI/mainwindow.h \
	GUI/init/initmainwindow.h
SOURCES += GUI/mainwindow.cpp \
	...

Another option, is to create a .pri file in each of the subdirectories. A .pri file is just like a .pro file, only it is mend to be included into another .pro file and is thus not a complete definition of a project by itself. In this case, you probably end up with something like this:

Project.pro:

SOURCES += main.cpp
include(GUI/gui.pri)


gui.pri:
HEADERS += mainwindow.h
SOURCES += mainwindow.cpp
include(init/init.pri)


init.pri:
SOURCES += initmainwindow.cpp


I use the second option often for some mini-components that I use in multiple applications. By just including the associated .pri file, I pull in the sources for these components and all that is needed into the application's project file. No need for an actual library in this case.

Coders,
could someone tell me how should a Qt project be compiled, when its structure is like:

project
-main.cpp
-GUI
--mainwindow.cpp
--mainwindow.h
--init
---initmainwindow.cpp

I just tried with CMake, but maybe you can suggest an example or give some advice (I like to make a tree of dirs/files rather than put them all into a single dir)?
