[Qt-creator] build settings for cross platform? multiple svn checkouts on each development computer

[nobodyhere]

Is there information on how to (svn commit) cross platform (Windows, Mac, Linux) build settings for a Qt Creator project, that doesn't have any absolute paths?

I created a new project on Windows, then (svn commit) it.  Then I did (svn checkout) of the project on Mac OS.  Unfortunately, I had to create a new set of build settings to get it to build / compile?  But it seems to be storing this build settings stuff in the [project].pro.user file, with absolute paths?

How can I fix it so that I can simplify for anyone to do multiple fresh (svn checkout)'s of the project on each machine (regardless of OS), and have the build / compile just work (for Windows, Mac, Linux builds) (with multiple checkouts per machine, using relative paths)?

Why are there absolute paths in this [project].user.pro file (for example, the buildDirectory has an absolute path)?

thank you for any leads
