[Qt-creator] Shadow Build Folder Location in QMake

[Robert Caldecott]

Hi, long time no post.

I have installed the Qt Creator 2.0 beta and have decided to try
shadow builds (as they are enabled by default).  The problem I have is
that some of my qmake .pro files are assuming that targets will end up
in ./debug, ./release, etc. which no longer works.  For example, the
following snippet will set a dependency:

CONFIG(debug, debug|release):OUTDIR = debug
else:OUTDIR = release
PRE_TARGETDEPS += ../ProjectName/$${OUTDIR}/someLib.a

This will now fail as the shadow build path is different.

So, what I want to do is simple - I want to be able to get the shadow
build location from my .pro file.  I've tried every qmake variable I
can think of but none of them help.  DESTDIR is always blank for
example.  The closest I've found is OUT_PWD but I really need one that
specifies a folder a level about this.

Before I give up on what seems to be a useful feature can anyone offer
me some advice?  I store all my dependency information in the main
.pro files and want to avoid anything that requires a user to set (so
changing .pro.user is out of the question.)

QMAKE_SHADOW_BUILD_DIR would be great obviously.  :)

Thanks in advance.
