Cannot compile ofxOpenNI examples

Hi,

I just installed openframeworks in combination with codeblocks. I want to use the kinect camera for my programm, so I installed the addon ofxOpenNI and tried to compile the examples of this addon.

But with every example I get the following errors:

  
Compiling: ..\..\..\addons\ofxOpenNI\src\ofxOpenNITypes.cpp  
Compiling: src\main.cpp  
Compiling: src\testApp.cpp  
Compiling: ..\..\..\addons\ofxOpenNI\src\ofxOpenNI.cpp  
Linking console executable: bin\openNISample007.exe  
mingw32-g++.exe: ..\..\..\libs\poco\lib\win_cb\libPocoNetmt.a: No such file or directory

mingw32-g++.exe: ..\..\..\libs\poco\lib\win_cb\libPocoFoundationmt.a: No such file or directory  

I checked this folder, but there are only files without mt. I could not find any solution in this forum yet.
Thanks for your help.
