[maemo-developers] QtCreator, libraries, and multiple platforms

[From: Daniil Ivanov]

Hi all!

 I agree that three project files are the way to go:

 Main project file:
 TEMPLATE = subdirs
 SUBDIRS = library application
 CONFIG += ordered

 Then use TEMPLATE= lib
 and TEMPLATE=app
 in library and application subdirectories project files.

 This is how you declare your library for your application
 http://doc.qt.nokia.com/latest/qmake-project-files.html#declaring-other-libraries

Thanks, Daniil
