[Qt-creator] Avoid rebuilding debugger helper on Mac?

[Stephen Chu]

I've been following 1.3.83 snapshots for some time. It's been working 
great. But every time I update to a new version on the Mac, I have to 
rebuild the debugger helper. I don't have to do the same with Windows 
version.

It turns out that the debugger helper info on the Mac is created inside 
of the application bundle. So every time I update to a new snapshot, the 
data is gone.

Is there a way to set where the helper data is stored? Thanks.
