That's pretty much exactly how I organise my code (except that I don't
distinguish between an "app" and "lib" folder - they live
side-by-side). In fact, starting with such a directory structure and a
"top-level" *.pro file with the SUBDIR template (you can also define
dependencies therein! It's manual work, yes, but it's worth the
effort: libraries upon which some binary/library depends are build
first - check the qmake documents!).
Here is another tip: I collect all my sources (for each library and
application) into "sources.pri".
For instance:
DEPENDPATH += $$PWD/GeneratedFiles \
$$PWD/src
HEADERS += $$PWD/src/UtilsLib.h \
$$PWD/src/PaintTools.h \
$$PWD/src/Settings.h
SOURCES += $$PWD/src/PaintTools.cpp \
$$PWD/src/Settings.cpp
I then have a top-level Translations.pro (at the same level as the
top-level *.pro file with the SUBDIRS template):
# Add all module sources here (except plugins)
include(Utils/Sources.pri)
include(Model/Sources.pri)
include(Resources/Sources.pri)
include(Kernel/Sources.pri
...
TRANSLATIONS = i18n/MyApp_fr.ts \
i18n/MyApp_de.ts \
i18n/MyApp_ru.ts ...
Once I run "lupdate Translation.pro" I get ONE *.ts translation file
per language (instead of multiple *.ts per library and executable).
That works because all my source.pri file have *relative* paths setup
with that funny $$PWD variable, which expands nicely relative to the
*.pro file which "includes" that sources.pri file (don't ask me how I
found out about that - I think it's an undocumented feature even - and
I always get confused when to use brackets (), or even {}, or double
{{}} - but in this case it seems to *only* work when using *no*
brackets: simply $$PWD ;)) It Simply Works ;)
In a similar way I also setup Common.pri and CommonLibrary.pri which
contains compiler directives common to all executables respective
libraries, a Build.pri which specifies DEBUG defines, version info
etc.. These *.pri files (all sitting in the top-level project folder)
are then included by the respective library/application *.pro project
files.
