I use similar approach, but I do qmake CONFIG+=sailfish
and then I can check for it in the .pro file like this:
sailfish {
DEFINES += Q_OS_SAILFISH
...
}
Looks shorter and cleaner to me :-)

Hi,
What Thomas said makes sense, I just want to add one more little thing.
You can, in the .spec file, add stuff to qmake, like this define. This
would make the necessary code shorter and as a bonus, it gives you
something you can even ifdef in C++.
# spec file
qmake DEFINES+=IS_SAILFISH_OS
# pro file
contains(DEFINES, IS_SAILFISH_OS) {
...
}
// C++ file
#if defined(IS_SAILFISH_OS)
...
#endif
Cheers,

In general, it might just be easier (and more maintainable) to have
a per-platform .pro file for your project and not litter your .pro
file with lots of conditionals (been there, done that - it will
become hard to read, understand and maintain as the number of
platforms grows). If there’s a lot of common things that you need in
each file, put that in a .pri file and include it in each
platform-specific .pro file. Then, in the sailfish .spec, you can
call qmake on the sailfish-specific project file, in the Maemo 5
debian/rules script, you call qmake on the maemo5 .pro file, etc…
With that said, you can use packagesExist[1] to do sailfish-specific
things if you are convinced that a single .pro file really is the
way to go:
packagesExist(sailfishapp) { .. do stuff .. }
Alternatively, set an environment variable in the qmake call in the
.spec file and check for that variable in the .pro file:
# In the .spec file:
IS_SAILFISH_OS=1 qmake
# In the .pro file:
IS_SAILFISH_OS = $$(IS_SAILFISH_OS)
contains(IS_SAILFISH_OS, 1) {
.. do stuff ..
}
HTH :)
