[Qt-creator] Build QT Creator with debug symbols

[Ion Ostafi]

Hi
     I am working on a QT Creator plugin and I am trying to build my 
plugin in Debug, but I have an error:
library not found for -lCore_debug. Consulting the output of the make in 
terminal , I found that this library is needed in the following path 
-L../qt-creator-build/bin/Qt\ Creator.app/Contents/PlugIns -lCore_debug.
It is not there, and I suppose that it is because I have built QT 
Creator in release mode. Trying to build Creator in Debug mode, the 
QTCreator itself is broken. How can I build creator in debug mode? or 
How can I build my plugin in debug mode ?
