As far as I understand I should put something like this in the opensse.pri
INCLUDEPATH += $$PWD \
C:/Program Files (x86)/PCL 1.7.2/3rdParty/Boost/include/boost-1_57 \
LIBS += -L/C:/opencv/build/x86/vc12/lib \
-lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_features2d -lopencv_ml \
LIBS += -L/C:/Program Files (x86)/PCL 1.7.2/3rdParty/Boost/lib \
I am sure, that this is wrong syntactically, but it should be something similar to this.
