Then I think you did not build the libraries via "src" folder. Right? Please 
build them.

You have not "cgalqt.lib". Also I recommend you build the "src" folder then 
add "cgalqt.lib" to "project properties->linker->input"

Did you add "cgalqt.lib", "qtmain.lib" and "qt-mt.lib" in "project 
properties->linker->input" section?
