Include a .pro file in Qt?

Question

I have a project which has lots of includepaths, source and header files. The project is run as a standalone application (it\'s not a library).

I would like to implement

You should perform two modifications:

1. Separate out all header files and build-specific settings into a *.pri file. This is what you need instead of including a *.pro.
2. Move all business logic into a library in order to be able to test it in a separate project.

E.g., you will have build.pri:

# build.pri
TOPDIR = $$PWD
INCLUDEPATH += . \
               $$TOPDIR/include

DEPENDPATH += $$TOPDIR

INCLUDEPATH += $$TOPDIR/additional/libararies

HEADERS += all.h \
           your.h \
           headers.h \
           of.h \
           interest.h

QT      += xml
# etc., etc.

and core.pro

# core.pro
TEMPLATE = lib

CONFIG  += dll thread create_prl
QT      += network xml xmlpatterns sql

include(../build.pri)

HEADERS  += \
            headers.h

SOURCES  += sources.cpp \
            many_of_them.cpp

TARGET     = core
# etc., etc.

(note the include(../build.pri)), and then make your main project app.pro as a subdirs project with core and gui as components of application, and test.pro with obligative core and as many tests as you want.
