QT path for Ubuntu

[Z.K.]

Where do I point CodeBlocks to find the QT directory.  I am not sure where it is in Ubuntu.

/usr/share/qt4/bin/
/usr/share/qt4/include/

Hi! I use Code::Blocks 10.05 on Ubuntu 12.04. I've installed Qt4 library files (through Synaptic).
When I was creating new Qt4 project, I had to set library location. Default it is a variable: $(#qt4), so I defined this variable as you can see at this picture: http://www.math.uni.wroc.pl/~wojak/cpp2/QtOrazCodeBlocks/GlobalVariableUbuntu.png
But I receive this information:

The macro you entered seems valid, but this wizard can't
locate the library directory based on this macro.
This wizard cannot continue.

I don't know what to do. Could you help me?
