Poco C++ using Raspberry Pi and Qt

Question

Is it possible to compile Poco libs such that I can use them on Raspberry Pi with my Qt project? Currently I have my Qt project up and running on Raspberry Pi except for the functions using Poco. I thought that I could compile Poco directly on Raspberry Pi and just copy the compiled libs and header files to my Ubuntu machine, which does the compiling of my Qt project. I included

INCLUDEPATH += /path/to/poco/libs/compiled/for/raspberrypi/include  
DEPENDPATH += /path/to/poco/libs/compiled/for/raspberrypi/include  
LIBS += -L/path/to/poco/libs/compiled/for/raspberrypi -lPocoFoundation -lPocoNet  
target.path = /home/pi/path/to/my/executable  
INSTALLS += target

in my .pro file.

But I get the following error the first time the compiler encounters a Poco include:

Answer 1

Ensure that you have set up your include paths for the Poco library itself correctly. Poco internal headers may need other directories than the root '/path/to/.../include/' path to be included into the include path.

Answer 2

These are the include paths your compiler is looking at. Is Poco/Net in there somewhere?

-I/usr/local/qt5pi/mkspecs/devices/linux-rasp-pi-g++ 
-I../../../BeatQtPlayer/src/pocowebserverplugin 
-I../../../BeatQtPlayer/src 
-I/home/jon/tmp/BeatQtPlayer/src/pocowebserverplugin/../../external_tools/poco-1.4.6p2/lib_raspberrypi/include 
-I/mnt/rasp-pi-rootfs/usr/local/qt5pi/include 
-I/mnt/rasp-pi-rootfs/usr/local/qt5pi/include/QtNetwork 
-I/mnt/rasp-pi-rootfs/usr/local/qt5pi/include/QtCore 
-I. 
-I.
